  Arteriovenous malformations can happen anywhere in your body, but occur most often in the brain, head, or neck. […] There are many options for AVM treatment. For this reason, it is important to be evaluated by a multidisciplinary cerebrovascular team capable of performing all of these possible treatments for an AVM. At Mount Sinai, we take a multidisciplinary approach to AVM treatment. Treatment options include observation, microsurgery, endovascular embolization, stereotactic radiosurgery, or a combination of these. […] Embolization, is the most common treatment for AVMs and consists of injecting a substance inside the abnormal arteries to block them off and decrease blood flow to the AVM. […] Microsurgery is a term for the surgical resection of an AVM. This is a common treatment option for AVMs that are surgically accessible and often provides a complete cure. […] Stereotactic radiosurgery is a noninvasive method to treat an AVM using targeted radiation in the radiation oncology department.

  Brain arteriovenous malformations (bAVMs) are complex, heterogeneous, and uncommon intracranial lesions. They can be treated by one or a combination of the following treatment modalities, namely embolization, radiosurgery, or microsurgical resection. […] A hybrid OR is always a better option while operating AVM. An experienced neurosurgical team is a prerequisite, and the armamentarium should include high end operating microscope, ultrasonic Doppler, indocyanine green (ICG), dual-image videoangiography, and endoscope to look beyond the nidus and confirm. These will add to the completion of surgery. Immediate check angiography is needed to check for residual nidus. […] Stereotactic radiosurgery (SRS) offers an acceptable risk to benefit profile for patients with unruptured bAVMs. SRS appears to be best suited for small-to-moderate-volume bAVMs that are generally 12 cm3 in volume or 3 cm in maximum diameter.

  In endovascular embolization, a long, thin tube called a catheter is inserted into a leg artery. The catheter is threaded through blood vessels to the brain using X-ray imaging. The surgeon positions the catheter in one of the arteries that feeds the AVM. An embolizing agent, such as small particles or a gluelike substance, is injected. The embolizing agent blocks the artery and reduces blood flow into the AVM. […] There are several treatments for brain arteriovenous malformation (AVM). The main goal of treatment is to prevent bleeding, known as a hemorrhage. Treatment also can help control seizures or other brain symptoms. […] Surgery is the most common treatment for brain AVMs. There are three surgical options: […] Surgical removal, known as resection.

  Treatment depends on the type of AVM, its location, symptoms, and the individuals general health. […] Whenever an AVM is detected, the individual should be carefully and consistently monitored for any signs that may indicate an increased risk of hemorrhage. […] There are several options for treating AVMs. Although medication can often lessen general symptoms such as headache, back pain, and seizures caused by AVMs and other vascular lesions, the definitive treatment for AVMs is either surgery or focused radiation therapy. […] Because so many variables are involved in treating AVMs, doctors must assess the danger posed on a case-by-case basis. A hemorrhage from an untreated AVM can cause serious neurological problems or death. For that reason, many doctors recommend surgical intervention whenever an AVM appears to pose a higher-than-usual risk of significant bleeding. However, surgery on any part of the brain or spinal cord carries some risk of serious complications or death.

  Brain arteriovenous malformations are a type of intracranial high-flow vascular malformation composed of enlarged feeding arteries, a nidus of vessels closely associated with the brain parenchyma through which arteriovenous shunting occurs and draining veins. […] Treatment options and rate of complications are dictated in part by the Spetzler-Martin grade. In general, the three options available are: microsurgical resection, endovascular occlusion, and radiosurgery. […] Occasionally, arteriovenous malformations have been known to spontaneously resolve, usually in the setting of intracranial hemorrhage, resulting presumably in venous compression and thrombosis. […] The annual risk of hemorrhage for an untreated arteriovenous malformation is 2-3%, resulting from a flow-related aneurysm, intra-nidal aneurysm, or venous thrombosis (rarely). […] Following hemorrhage, the risk of a further bleed in the next 12 months is up to 18%.

  https://www.bafound.org/understanding-brain-aneurysms/arteriovenous-malformations/

  The goal of AVM treatment is to prevent hemorrhage, with an annual risk of 2-4%, higher if previously occurred. The risk exists even without symptoms. Treatment decisions consider the patient’s age, health, AVM location and size, and symptoms. […] Major Treatments: Surgery (microsurgical resection): Invasive procedure to remove the AVM, performed under general anesthesia. Hospital stay is typically four to six days, with at least one day in the ICU. […] Stereotactic Radiosurgery: Non-invasive, uses focused radiation beams to destroy the AVM over about three years. Effective for small AVMs or those in critical brain areas. Completed in one to three sessions with a 70-80% success rate. […] Embolization (endovascular surgery): Minimally invasive, uses materials to plug blood vessels supplying the AVM via a catheter. Often combined with surgery or radiosurgery to reduce AVM size. […] Medical Management: Regular monitoring and symptom management, suitable for patients with high surgical risks or large AVMs in critical brain areas.

  https://www.ninds.nih.gov/health-information/disorders/arteriovenous-malformations-avms

  Three surgical options are used to treat AVMs: conventional surgery, endovascular embolization, and radiosurgery. The choice of treatment depends largely on the size and location of an AVM. Endovascular embolization and radiosurgery are less invasive than conventional surgery and offer safer treatment options for some AVMs located deep inside the brain. […] Conventional surgery involves entering the brain or spinal cord and removing the central portion of the AVM, including the fistula, while causing as little damage as possible to surrounding neurological structures. […] Endovascular embolization involves guiding a catheter though an artery until the tip reaches the site of the AVM. The surgeon then injects a substance (such as fast-drying glue-like substances, fibered titanium coils, or tiny balloons) that will travel through blood vessels and create an artificial blood clot in the center of the AVM.

  The obliteration rate of endovascular embolization alone does not exceed 60%. […] Surgery is curative and definitive. […] Any form of treatment directed for AVMs should have complete obliteration of the nidus. Alternatively: Complete occlusion of AVM is the only acceptable target of any treatment. […] Presurgical embolization helps in reducing the size of the nidus and the risk of hemorrhage during surgery. […] Microsurgical resection allows a high rate of complete nidus obliteration and immediately eliminates hemorrhage risk with a long-term durability when compared to other treatment options.

  https://www.aaroncohen-gadol.com/en/patients/arteriovenous-malformation/survival/recovery-outlook

  Arteriovenous malformations (AVMs) are abnormal blood vessels with improper artery-to-vein connections. Most people do not experience symptoms until the AVM ruptures. […] Fortunately, AVMs can be cured through surgery, sometimes in combination with other treatment options such as endovascular embolization and radiosurgery. […] AVM treatment options include surgery, endovascular embolization, and/or radiosurgery. The decision to pursue one treatment option over another is dependent on characteristics of the patient and the AVM. […] Prevention of AVM rupture is the primary goal of treatment, but the risk of AVM rupture is different for each patient. […] Surgery: The AVM is surgically removed, and blood flow is rerouted to healthy vessels. Because AVMs do not usually regrow, complete removal of the AVM results in an immediate and permanent cure.

  Endovascular embolization is a minimally invasive approach that involves inserting a tiny flexible tube (catheter) into the groin. […] Despite having surgery in its name, radiosurgery is actually just a type of radiation therapy that uses targeted radiation beams to shrink, scar, and eventually choke off blood flow to the AVM over a period of time. […] Prevention of AVM rupture and these potential neurological complications is the primary goal of treatment. However, treatment comes with its own risks. […] In general, all treatment options have low neurological complication (morbidity) rates of less than 10% and very low death (mortality) rates of 1-2%. […] When comparing treatment methods in isolation, surgery offers the best chance of a cure.

  Arteriovenous malformation treatment options often include one of three types of AVM surgery but may start with careful monitoring. Following an AVM diagnosis, which will show a group of non-cancerous blood vessels forming incorrectly, doctors will discuss AVM treatment options. These include endovascular embolization for AVM, stereotactic radiosurgery for AVM (also known as Gamma Knife surgery for AVM) and microvascular neurosurgery. […] The best AVM procedure option is determined based on the location of the AVM, patient symptoms, patient health and other risks. With any surgery near or at the brain, including brain surgery for AVM, precaution is needed, as an AVM may be in a location that increases risk of tissue damage. If an AVM is growing or shows a risk of bleeding, AVM treatment options may be needed. The goal of any AVM treatment is to either cure the AVM or reduce its impact.

  https://www.uclahealth.org/medical-services/radiology/interventional-neuroradiology/diseases-treated/arteriovenous-malformation

  Embolization is a procedure to block abnormal blood vessels in the nidus of the AVM. In other words, the shunts in the nidus are blocked one by one during the embolization procedure. This is an angiogram based procedure and not a surgical procedure. It is referred to as a minimally invasive procedure, as unlike surgery, no cutting in the head or skull or manipulation of the brain is involved. […] The role of embolization in treatment of AVMs? Embolization is rarely curative on its own. It usually does not replace surgery or radiations which are needed to completely cure the AVM. The embolization procedure is very helpful when performed before surgery or radiation. For instance, before surgery, embolization is useful as it blocks the shunts, so that there isn’t as much bleeding during surgery. Prior to radiation, by blocking the shunts, the size of the AVM can be reduced and hence the area that has to be radiated is smaller. The smaller the area radiated the less chance that the radiation can damage the brain tissue around the AVM.

  Superselective endovascular treatment includes delivery of thrombosing agents such as quick-acting acrylate glue (N -butyl cyanoacrylate [NBCA]), thrombus-inducing coils, Onyx liquid embolic fluid, or small balloons into the AVM nidus. […] The goal of embolization is to block the high-velocity shunting of blood from the high-pressure arterial system into the venous system. […] Radiosurgery is an option that is generally used to treat AVMs that are approximately 3 cm in diameter or less. […] Controversies are noted in regard to the sequence of combined treatment commonly advocated to treat large AVMs. […] Treatment of arteriovenous malformations (AVMs) is best achieved with a multispecialty team comprising a neurologist, neuropsychologist, neurosurgeon, interventional neuroradiologist, and neuroanesthesiologist.

• #24 Endovascular Treatment of Cerebral AVMs – Endovascular Today

  https://evtoday.com/articles/2005-july/EVT0705_F4_Gailloud.html

  Successful management of cerebral arteriovenous malformations has become a reality. […] The modern management of cerebral AVMs is based on three therapeutic modalities: conventional microneurosurgery, endovascular embolization, and stereotactic radiosurgery. […] Combined AVM therapy by embolization and surgery has even proved superior to surgery alone in cost-effectiveness analyses. […] When not primarily curative, embolization facilitates subsequent radiosurgery by reducing the volume of the nidus (in particular for AVMs larger than 10 mL), prepares the resection of surgically accessible AVMs, and immediately addresses the risks related to associated intra- and extranidal aneurysms and arteriovenous fistulas. […] Although many AVMs can, from a technical standpoint, be totally embolized, partial embolization followed by surgery or radiosurgery may be ultimately more satisfying in terms of functional outcome.

  https://www.bcm.edu/healthcare/specialties/neurosurgery/cerebrovascular-and-stroke-surgery/brain-arteriovenous-malformations-avms

  Neurosurgery is often the best option for small to medium size AVMs in favorable areas of the brain because it allows for the immediate and complete cure of the AVM, with a good safety profile. […] It is rare to cure an AVM with embolization alone. This strategy is often used prior to neurosurgery to decrease the blood flow in the AVM, making neurosurgery safer. […] Stereotactic radiosurgery, also known as radiosurgery, involves aiming multiple focused beams of radiation that converge at the AVM. Ultimately, a high dose of radiation is absorbed by the AVM, but very little radiation is absorbed by the surrounding brain. Over time, this radiation exposure narrows and shrinks the AVM blood vessels until they go away. However, the downside of this treatment is that it may take two to three years for the AVM vessels to shrink away, and during this time, there is still a risk of bleeding. Furthermore, only approximately 70-80 percent of patients are ultimately cured with this technique.

  This less-invasive form of treatment is a one-day outpatient procedure in which beams of radiation are precisely focused on the AVM, causing it to shrink over time. In most patients, the AVM will be cured in 1-3 years after treatment. Such radiosurgery is most useful for smaller AVMs, but can be used selectively for the treatment of larger AVMs. […] Endovascular embolization is primarily used in preparation for surgery or radiosurgery to make the treatments safer and more effective.

  What happens during an embolization procedure? Patients undergoing embolization procedure at our institution are placed under general anesthesia. This means that the patient will be completely unconscious during the procedure. The embolization procedure is performed as described above. The patient is then awakened after the procedure and will spend one night in the hospital for observation. Patients are then discharged home the next day. We would recommend one additional day of rest at home prior to resuming normal pre-procedure activities. Sometimes, due to the size of the AVM, several embolization sessions are necessary. Each session would be performed separately perhaps separated by days or one or two weeks and each session would proceed as described above with one night stay at the hospital.

  Embolization is effective for treating these intranidal aneurysms, which represent a likely site for AVM rupture, and should constitute a primary target of endovascular therapy. […] Complications potentially associated with endovascular therapy of cerebral AVMs using any type of embolic agent comprise the risks of ischemic and hemorrhagic stroke leading to transient or permanent neurologic deficits, including death. […] Although reviews with significant complication rates have recently been used to caution against transarterial embolization, numerous series reporting low morbidity and mortality rates have now established the safety and efficacy of endovascular therapy, even for AVM in challenging locations such as the rolandic cortex or the basal ganglia. […] Partial, noncurative embolization can be used as a form of palliative treatment either to improve the patient’s clinical condition or to reduce the risk of hemorrhage.

  The risk of normal perfusion breakthrough phenomenon (ie, the occurrence of postprocedural edema and hemorrhages in cerebral tissue adjacent to the AVM nidus) is more concerning. […] It is believed that the perfusion breakthrough phenomenon corresponds to a disruption of the chronically ischemic capillary bed that surrounds the AVM secondary to the sudden increase in perfusion pressure resulting from nidus resection or embolization. […] As a rule of thumb, we tend to avoid embolizing more than one third to one half of a large nidus in a single treatment session, keeping a 4- to 6-week interval between successive procedures. […] The importance of having the embolic agent penetrate the AVM nidus rather than simply occlude its feeders was recognized early by Vinuela et al as a key factor in preventing nidus recanalization.

  Arteriovenous malformation treatment options often include one of three types of AVM surgery but may start with careful monitoring. Following an AVM diagnosis, which will show a group of non-cancerous blood vessels forming incorrectly, doctors will discuss AVM treatment options. These include endovascular embolization for AVM, stereotactic radiosurgery for AVM (also known as Gamma Knife surgery for AVM) and microvascular neurosurgery. […] The best AVM procedure option is determined based on the location of the AVM, patient symptoms, patient health and other risks. With any surgery near or at the brain, including brain surgery for AVM, precaution is needed, as an AVM may be in a location that increases risk of tissue damage. If an AVM is growing or shows a risk of bleeding, AVM treatment options may be needed. The goal of any AVM treatment is to either cure the AVM or reduce its impact.

  The goal of AVM treatment is to prevent hemorrhage, with an annual risk of 2-4%, higher if previously occurred. The risk exists even without symptoms. Treatment decisions consider the patient’s age, health, AVM location and size, and symptoms. […] Major Treatments: Surgery (microsurgical resection): Invasive procedure to remove the AVM, performed under general anesthesia. Hospital stay is typically four to six days, with at least one day in the ICU. […] Stereotactic Radiosurgery: Non-invasive, uses focused radiation beams to destroy the AVM over about three years. Effective for small AVMs or those in critical brain areas. Completed in one to three sessions with a 70-80% success rate. […] Embolization (endovascular surgery): Minimally invasive, uses materials to plug blood vessels supplying the AVM via a catheter. Often combined with surgery or radiosurgery to reduce AVM size.

  When deciding on whether to treat an un-ruptured AVM, it is necessary to consider the estimated lifetime risk of rupture compared to the estimated risk of treatment. […] The size, location, and venous drainage of an AVM are taken into account when determining the risk from surgical removal. […] With some AVMs the estimated risk of surgical removal is significantly smaller than the lifetime risk of rupture and therefore surgical removal is a recommended option. Whereas other AVMs are too risky to resect surgically and it may be safer not to operate on them. […] Micro-surgery is still considered the best treatment option when its performed safely. This is because it carries around 95% chance of instant cure. In some cases, microsurgery is too risky and other treatment options can be considered. These include stereotactic radiosurgery (SRS) or embolisation.

  The preferred treatment of Spetzler-Martin grade 1 and 2 AVMs in young, healthy patients is surgical resection due to the relatively small risk of neurological damage compared to the high lifetime risk of hemorrhage. Grade 3 AVMs may or may not be amenable to surgery. Grade 4 and 5 AVMs are not usually surgically treated. […] Radiosurgery has been widely used on small AVMs with considerable success. The Gamma Knife is an apparatus used to precisely apply a controlled radiation dosage to the volume of the brain occupied by the AVM. […] Embolization is performed by interventional neuroradiologists and the occlusion of blood vessels most commonly is obtained with ethylene vinyl alcohol copolymer (Onyx) or n-butyl cyanoacrylate. These substances are introduced by a radiographically guided catheter, and block vessels responsible for blood flow into the AVM. […] Embolization reduces the size of the AVM and during surgery it reduces the risk of bleeding. However, embolization alone may completely obliterate some AVMs.

  Successful management of cerebral arteriovenous malformations has become a reality. […] The modern management of cerebral AVMs is based on three therapeutic modalities: conventional microneurosurgery, endovascular embolization, and stereotactic radiosurgery. […] Combined AVM therapy by embolization and surgery has even proved superior to surgery alone in cost-effectiveness analyses. […] When not primarily curative, embolization facilitates subsequent radiosurgery by reducing the volume of the nidus (in particular for AVMs larger than 10 mL), prepares the resection of surgically accessible AVMs, and immediately addresses the risks related to associated intra- and extranidal aneurysms and arteriovenous fistulas. […] Although many AVMs can, from a technical standpoint, be totally embolized, partial embolization followed by surgery or radiosurgery may be ultimately more satisfying in terms of functional outcome.

  The multidisciplinary evaluation and treatment of brain AVMs continues to evolve. Recommendations include: (1) Digital subtraction catheter cerebral angiography (DSA) including 2D, 3D, and reformatted cross-sectional views when appropriate is recommended in the pre-treatment assessment of cerebral AVMs. (I, B-NR). (2) It is recommended that endovascular embolization of cerebral arteriovenous malformations be performed in the context of a complete multidisciplinary treatment plan aiming for obliteration of the AVM and cure. (I, B-NR). (3) Embolization of brain AVMs before surgical resection can be useful to reduce intraoperative blood loss, morbidity, and surgical complexity. (IIa, B-NR). (4) The role of primary curative embolization of cerebral arteriovenous malformations is uncertain, particularly as compared with microsurgery and radiosurgery with or without adjunctive embolization. Further research is needed, particularly with regard to risk for AVM recurrence. (III equivocal, C-LD). (5) Targeted embolization of high-risk features of ruptured brain AVMs may be considered to reduce the risk for recurrent hemorrhage. (IIb, C-LD). (6) Palliative embolization may be useful to treat symptomatic AVMs in which curative therapy is otherwise not possible. (IIb, B-NR). (7) The role of AVM embolization as an adjunct to radiosurgery is not well-established. Further research is needed. (III equivocal, C-LD). (8) Imaging follow-up after apparent cure of brain AVMs is recommended to assess for recurrence. Although non-invasive imaging may be used for longitudinal follow-up, DSA remains the gold standard for residual or recurrent AVM detection in patients with concerning imaging and/or clinical findings. (I, C-LD). (9) Improved national and international reporting of patients of all ages with brain AVMs, their treatments, side effects from treatment, and their long-term outcomes would enhance the ability to perform clinical trials and improve the rigor of research into this rare condition. (I, C-EO) […] Although the quality of evidence is lower than for more common conditions subjected to multiple randomized controlled trials, endovascular therapy has an important role in the management of brain AVMs. Prospective studies are needed to strengthen the data supporting these recommendations.

  There are several ways to treat brain or spinal AVMs. The neurosurgeon will discuss available options for each patient depending on the location and size of the AVM, as well as the patients age and overall health. If appropriate, noninvasive or minimally invasive methods will be considered. Treatment options for AVMs include: […] Observation and medication may be appropriate in some cases, and some AVMs dont need to be treated at all. The doctor may decide to observe the patient and watch for any changes. The patient may need to take anticonvulsant medication to prevent seizures or medication to lower blood pressure. In children, an AVM grows as the childs body grows, so monitoring AVM growth is especially important to prevent complications and relieve symptoms. […] Stereotactic radiosurgery uses targeted radiation to destroy the AVM without entering the skull. The radiation causes the blood vessels in the AVM to regress (go back to their previous state) slowly during the months or years after the treatment. This noninvasive therapy works best for small AVMs or an AVM that has not already caused considerable bleeding.

[…] For postoperative treatment, patients are divided to three groups, based on the AVM characteristics and surgical complications (SMG and whether or not the AVM had ruptured preoperatively). […] According to the Helsinki protocol, good collaboration between neuroradiologist, neurosurgeon and neuroanesthesiologist is essential when deciding the postoperative treatment. […] The Helsinki protocol used for all the patients in this study focuses on patients blood pressure and intravenous fluid regimen. […] The benefits of simpler protocols are multifarious such as making the implementation of the protocol easier, decreasing the chance for treatment personnel error and reducing the risk for treatment related adverse event. […] Further study with greater study size would be required to produce more rigorous evidence for postoperative treatment of microsurgically resected bAVMs; however, thus far Helsinki protocol seems to perform adequately.

  However, when using embolization or radiosurgery alone, the likelihood of obtaining a cure is lower than that of surgery. Endovascular embolization may also be used with palliative intent to alleviate AVM symptoms. […] While living with an AVM, these are some things you can do to manage your condition: Stay on top of your medical care. This means attending all appointments and taking any medications prescribed by your doctor. […] Fortunately, most patients living with an AVM can live long and full lives. Some individuals live with an AVM for life without it ever being detected. Cure rates after surgery are as high as 100% in patients with low-grade AVMs, and a combination of treatment options are available for more complex cases. […] Each treatment and outcome are unique to every patient, but a skilled neurosurgeon and medical team can make a world of difference. Seek an experienced neurosurgeon for a comprehensive evaluation and discussion of how to best manage your AVM.

• #70 AVM Surgery Procedure Types, Risks, and Recovery

  https://www.healthline.com/health/avm-surgery

  All types of AVM surgery may have the following side effects and risks: headache, nausea, fatigue, infection, stroke or seizure, artery damage. […] The three types of AVM surgery range from radiosurgery, which is noninvasive, to resection, which is the most invasive type. […] The recovery depends on the type of AVM surgery. […] After AVM surgical removal that has no complications, you’ll probably stay in the hospital for 4-6 days and spend at least the first day in the intensive care unit (ICU). […] In a small 2021 study with 44 people whose AVMs were surgically removed, researchers found that 88% of them had a good outcome 3 months later. […] The only way to completely remove an AVM is through resection, but it’s a high risk surgery. […] Less invasive surgeries are endovascular embolization and radiosurgery. They both reduce the size of the AVM and may obliterate it over time.

  Arteriovenous malformation treatment options often include one of three types of AVM surgery but may start with careful monitoring. Following an AVM diagnosis, which will show a group of non-cancerous blood vessels forming incorrectly, doctors will discuss AVM treatment options. These include endovascular embolization for AVM, stereotactic radiosurgery for AVM (also known as Gamma Knife surgery for AVM) and microvascular neurosurgery. […] The best AVM procedure option is determined based on the location of the AVM, patient symptoms, patient health and other risks. With any surgery near or at the brain, including brain surgery for AVM, precaution is needed, as an AVM may be in a location that increases risk of tissue damage. If an AVM is growing or shows a risk of bleeding, AVM treatment options may be needed. The goal of any AVM treatment is to either cure the AVM or reduce its impact.

  Sometimes an arteriovenous malformation (AVM) is found incidentally, meaning that it hasnt caused any symptoms but is found during a CT or MRI scan performed for another reason (for example, after an accident or injury). […] A neurosurgeon evaluating the diagnostic angiogram will discuss treatment options with the patient and make a recommendation based on the risk of a rupture or other complications balanced against the risks of surgical intervention. The recommended treatment plan will be based not only on the angiogram but also on the patient’s clinical history, age, symptoms, and a physical examination. […] The decision to treat a cerebral AVM depends on its location, the risk of future complications if it is left untreated, and the risk of neurological deficits that may be associated with its treatment.

  Surgical extirpation is strongly suggested as the primary treatment for Spetzler-Martin grade I and II if surgically accessible with low risk. […] Radiation therapy alone is recommended for Spetzler-Martin grade I or II if the AVM is less than 3 cm in size and surgery has an increased surgical risk based on location and vascular anatomy. […] Brain AVM of Spetzler-Martin grades III can often be treated by a multimodal approach with embolization followed by surgical extirpation. […] AVMs of Spetzler-Martin grade IV and V are often not amenable to surgical treatment alone because of the high procedural risk. […] In general, embolization should only be performed if the goal is complete AVM eradication with other treatment modalities. […] Surgical resection is the mainstay of definitive treatment and is most effective with more easily accessible lesions of smaller size.

• #76 Cerebral arteriovenous malformation – Wikipedia

  The preferred treatment of Spetzler-Martin grade 1 and 2 AVMs in young, healthy patients is surgical resection due to the relatively small risk of neurological damage compared to the high lifetime risk of hemorrhage. Grade 3 AVMs may or may not be amenable to surgery. Grade 4 and 5 AVMs are not usually surgically treated. […] Radiosurgery has been widely used on small AVMs with considerable success. The Gamma Knife is an apparatus used to precisely apply a controlled radiation dosage to the volume of the brain occupied by the AVM. […] Embolization is performed by interventional neuroradiologists and the occlusion of blood vessels most commonly is obtained with ethylene vinyl alcohol copolymer (Onyx) or n-butyl cyanoacrylate. These substances are introduced by a radiographically guided catheter, and block vessels responsible for blood flow into the AVM. […] Embolization reduces the size of the AVM and during surgery it reduces the risk of bleeding. However, embolization alone may completely obliterate some AVMs.

  Our AVM Program includes national leaders in the diagnosis and treatment of AVMs. We are skilled in treating AVMs that others have deemed difficult or inoperable. […] Every week our team of cerebrovascular neurosurgeons, neurologists and interventional radiology specialists meets to discuss patients with cerebrovascular diseases, including AVMs, so we can determine the best AVM treatment options. […] The goal is to cure the brain AVM with the least overall risk and best overall outcome for each person. […] Endovascular Embolization is a technique performed by our endovascular neurosurgeons. The purpose of this procedure, which uses a catheter to insert a glue-like substance, is to prevent blood flow to the AVM. This AVM treatment option is used in conjunction with surgery or as a stand-alone treatment.
