• #1 Central nervous system vascular malformations: A clinical review

  https://pmc.ncbi.nlm.nih.gov/articles/PMC7886037/

  CNS vascular malformation is an umbrella term that encompasses a wide variety of pathologies, with a wide range of therapeutic and diagnostic importance. […] Advances in neurovascular imaging along with increased utilization of these advances, have resulted in more frequent identification of these lesions. […] In this review, we will outline epidemiological, clinical, radiological, and therapeutic features of intracranial and spinal cord vascular malformations and discuss syndromes associated with CNS vascular malformations. […] Understanding the pathophysiology, natural history, and characteristics predictive of the risk of rupture are all essential for clinicians when making appropriate therapeutic decisions. There are two main branches of therapy intervention or medical management. Medical management, or observation, includes treating risk factors for rupture such as hypertension and smoking cessation, and treating symptoms of the lesion itself, including headache and seizures. Surgical and radiologic interventions include endovascular therapy, surgery, and radiotherapy alone or in combination.

  Treatment of a central nervous system vascular malformation depends on the type of malformation, where it’s found, symptoms it causes and the risk of a bleed. Sometimes watching for changes in the malformation and for the risk of bleeding might be all that’s needed. […] Medicines that might be used for treating the symptoms of a venous malformation include anti-seizure medicines to treat seizures and pain relievers for headaches. […] Some central nervous system vascular malformations that pose a high risk of bleeding can be removed. The procedure depends on the malformation. […] Surgery. This involves cutting into the brain or spinal cord to remove the malformation. Surgery is most often used for an arteriovenous malformation that is small and in a place that’s easy to reach. […] Stereotactic radiosurgery. This uses radiation beams that are aimed exactly at the vascular malformation. The radiation damages the walls of the blood vessels of the malformation and causes it to go away over time.

• #3 Vascular Malformations: Symptoms, Treatment and Outlook

  https://my.clevelandclinic.org/health/diseases/23409-vascular-malformations

  Vascular malformations, or abnormal blood vessel changes, include venous malformations and arteriovenous malformations (AVMs). Treatments can close the affected blood vessels. […] Treatments for vascular malformations focus on minimizing symptoms and reducing potential complications. Malformations that dont cause problems may not need treatment and can just be observed over time. […] Treatments depend on the affected blood vessels. They often involve closing off or surgically removing affected blood vessels. Most malformations can be treated using minimally invasive techniques. Providers may use: Sclerotherapy. Catheter embolization. Laser treatments. Radiation therapy (radiosurgery). […] Due to the complexity and rarity of vascular malformations, its best managed using a team approach with health care providers of multiple specialties. […] Yes, vascular malformations can recur after treatment. You may need regular follow-up and testing to detect a recurrent malformation.

  Vascular malformations are frequent in the head and neck region, affecting the nervous system. […] We concluded that the correct anatomical, morphological, and functional characterization of cerebral vascular malformations by means of various imaging studies is highly relevant in determining the therapeutic approach, and that new lines of therapeutic approaches continue to depend on the imaging evaluation of these lesions. […] The way to approach these anomalies depends on the specific characteristics that they exhibit. […] Therefore, it is important to know the main characteristics of simple group vascular malformations, according to ISSVA criteria, which are present in the nervous system, to achieve correct identifications, characterizations, and therapeutic approaches. […] In general, sclerotherapy is the first-line treatment for symptomatic VMs.

  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. […] The proper treatment depends on your age, health, and the size and location of the brain AVM. […] Medicines may be used to treat symptoms caused by the AVM, such as headaches or seizures.

  The primary therapeutic intervention is endovascular therapy. […] The main therapeutic approach to DVAs is observation, given their function as normal venous channels, unless presenting with bleeding, infarct, or mass effects. […] Surgical resection with or without prior endovascular embolization is the only therapeutic option. […] Therapeutic strategies for cavernous malformations are largely based on symptoms and location. There are no large randomized clinical trials for resection versus observation for asymptomatic lesions. However, there are large observational studies to suggest consideration of surgical evaluation in patients with lesions in the brain stem, eloquent cortex, history of hemorrhage, and medically refractory epilepsy. […] If conservative therapy is not successful or symptoms are severe endovascular therapy is the first-line therapy with a range of 55-99% success rate in the literature.

  UT Southwestern Medical Center treats every kind of vascular malformation of the brain, including the rarest types of these blood vessel disorders. […] Every patients case is reviewed by all our cerebrovascular specialists before any treatment begins. In some cases, observation is the best strategy. In other cases, interventional treatment is warranted to minimize the risk of bleeding or stroke from a vascular malformation. […] Open surgery is the longest-established treatment for vascular malformations of the brain. […] This procedure involves injecting liquid glue or tiny metal coils via a catheter to block the blood supply to the malformation. […] Our experienced neurosurgeons now have the ability to combine endovascular and surgical procedures in the same operative suite. […] This procedure involves directly targeting a single treatment of high-energy radiation delivered by a linear accelerator (or Gamma Knife or CyberKnife) to cause the abnormal vessels to close over time. […] In some cases, immediate treatment might not be necessary or recommended because the vascular malformation might not be in danger of rupturing or bleeding, or there are no symptoms, or surgery might be considered too dangerous.

  Treatment may be conservative or interventional depending on lesion features, clinical presentation and patient specific factors. Treatment options include endovascular embolization via catheter delivery of liquid embolics or coils, microsurgical resection, and stereotactic radiosurgery (e.g., Gamma knife). Embolization alone rarely represents a curative treatment. However, a reduction in the size of the nidus or AVM flow may enable the performance of stereotactic radiosurgery or facilitate surgical removal. The risk of all treatment modalities should be weighed against the natural history risks of AVMs. The Spetzler-Martin (SM) grading scale is utilized as a decision tool to estimate the risk of surgical resection by evaluating the AVM size, pattern of venous drainage and eloquence of brain location, with higher grades of 4 and 5 being associated with greater surgical morbidity and mortality. Generally, AVMs with high grades are managed with conservative management due to rupture risk and worse prognosis with operative treatment including partial resection. Further, there is evidence that medical management alone of unruptured AVMs of the brain is superior to interventional therapy or medical plus interventional therapy at 5 year follow up.

  Acute: Observation, medical management and emergent surgical intervention may be warranted based on AVM characteristics and clinical presentation. With acute hemorrhagic presentation, prompt life saving measures to prevent further neurologic compromise are essential. Definitive treatment may be delayed to allow for characterization, healing, or adjuvant therapy as part of a staged treatment plan due to the size, location and complexity of the lesion. However, despite variances in clinical courses, treatment outcomes, and complications, pediatric patients with AVMs who underwent acute inpatient rehabilitation saw improvement in their WeeFIM scores upon discharge. […] Subacute: Depending on the location and type of vascular malformation, subsequent monitoring of the lesion with symptom presentation and imaging studies is done. This will guide further need for surgical intervention with a goal of lesion obliteration and prevention of re-bleeding and further neurologic sequela. In some asymptomatic AVMs that are incidentally found, clinical observation with monitoring is appropriate.

Importantly, in addition to the angiographic change, the patient had no new neurological signs or symptoms referable to the cord AVM. […] A planned trial will evaluate this strategy for patients with non-CNS AVMs in the near future (NCT04258046). For CNS cases, there may be a role for trametinib for patients with inoperable lesions and/or larger lesions that could be downsized to improve radiosurgical or microsurgical treatments.

  Physiotherapy (PT) plays an important role among the conservative therapy methods, as it has a corrective effect on functional disorders of the locomotor system. PT should therefore be used early and consistently. […] Analgesics, anticoagulants and in selected cases immunomodulators as well may be indicated in the treatment of venous malformation. Painkillers should be prescribed when a pain-free daily routine cannot be achieved by other measures such as compression, exercise and cooling. […] Anticoagulation with coumadin, direct oral anticoagulants (DOACs) or heparin are indicated in cases of recurrent thrombophlebitis or thromboembolism. […] The immunosuppressant drug sirolimus has been used in selected cases of venous malformations for a few years. It can potentially prevent progression of the clinical picture in the case of rapidly progressive segmental overgrowth and bleeding of large-volume vascular malformations that cannot be controlled in any other way.

  Surgeons create an opening in the skull (a craniotomy) with computer imaging guidance (usually MRI-based). Using a high-power microscope, surgeons remove the AVM and cauterize (or burn) its feeder blood vessels. Complete removal is confirmed with cerebral angiography. This procedure can provide an immediate cure by eliminating the risk of future bleeding and it is often the preferred option for ruptured AVMs. […] Computer imaging is used to guide a single high dose of radiation directly to the AVM. No incision is required. This procedure is typically used for AVMs that cannot be reached by surgery. […] We are experts in minimally invasive techniques that repair veins and arteries, reduce brain bleeding, and restore healthy blood flow. These options have less risk than traditional open surgery and are much better tolerated.

  Treatment depends on the size, location, and symptoms of the arteriovenous malformation. Your doctor may recommend one or a combination of the following treatments: […] Neurosurgery – The arteriovenous malformation is removed from the brain using microsurgical techniques that close the abnormal feeding arteries, separate the tangle from the adjacent brain, and cut the veins draining the AVM. […] Endovascular embolization – In this minimally invasive technique, a catheter is guided through the network of arteries until the tip reaches the site of the AVM. Various branches of the AVM are then plugged with a material such as glue or polymer cast. Embolization is usually used as a precursor to surgery to reduce the blood flow through the AVM, but can be used as a stand-alone treatment in some cases.

  Radiosurgery – In this noninvasive procedure, focused beams of radiation are targeted at the AVM and, over the course of 2-3 years, the arteries respond by scarring and closing down. Radiosurgery can be curative or can shrink an AVM down to a size that is more favorable for surgery. Gamma Knife and Cyberknife radiosurgeries are offered at Barrow. […] An AVM can be completely cured by surgical resection. If the entire AVM is successfully removed by surgery, then it is considered cured. An AVM can also be completely obliterated by radiosurgery over time (2-3 years), but efficacy rates are lower (50-80% depending on its size). Embolization can cure a smaller number of carefully selected AVMs. […] However, if a non-bleeding AVM converts to a bleeding AVM, the resulting complications and neurological deficits that might require treatment.

  The risk of AVM rupture was evaluated in the A Randomized trial of Unruptured Brain Arteriovenous malformations (ARUBA) trial. This study revealed a decreased risk of stroke and mortality in patients managed conservatively versus patients who underwent interventional therapy. […] The Spetzler-Martin AVM Grading System was developed in 1986 to determine the risk of morbidity and mortality of open surgical resection of intracranial AVMs. […] Endovascular embolization can be used to decrease the AVM nidus volume prior to stereotactic radiosurgery. […] The ultimate goal of intervention is to obliterate the AVM nidus and all arteriovenous shunt locations. […] The risk of perioperative morbidity and mortality increases with increasing Spetzler-Martin grade. […] AVMs smaller than 3cm in diameter with deep draining veins within the eloquent cortex are ideal for stereotactic radiosurgery as the morbidity and mortality of open surgical resection of these lesions are the highest. […] The complications of SRS for AVM treatment include seizure and hemorrhage. […] The prognosis of an intracranial AVM is dependent on a history of rupture.

  https://www.intechopen.com/chapters/69610

  In 2014, ARUBA (a randomized trial on cerebral Arteriovenous Malformation AVM) found patients treated using prevalent interventional strategies are three times more likely to suffer a stroke/die compared with those treated conservatively (blood pressure reduction). […] Thus, a clear accord emerges. There is a lacuna/weakness of interventional modalities when addressing high SM grade AVMs. This lack of a clear treatment choice originated our review. We attempt to identify the advantages and challenges of each present treatment/evaluation modality and highlight core requirements for future strategies. We conclude that existing modalities provide substantial recent improvements, yet the core challenge persists. Finally, we advocate testing a novel modality intraluminal radiotherapy (active implants) by exploiting the candy wrapper or edge effect. If proven effective, this approach could offer gradual vessel occlusion with minimal abrupt hemodynamic changes known to induce hemorrhage, the lowest recurring session number (reduced costs), minimally invasive attributes and very low radiation (dose/dose rate) kinetics minimizing potential Adverse Radiation Effects (AREs).

  The risk of AVM rupture was evaluated in the A Randomized trial of Unruptured Brain Arteriovenous malformations (ARUBA) trial. This study revealed a decreased risk of stroke and mortality in patients managed conservatively versus patients who underwent interventional therapy. […] The Spetzler-Martin AVM Grading System was developed in 1986 to determine the risk of morbidity and mortality of open surgical resection of intracranial AVMs. […] Endovascular embolization can be used to decrease the AVM nidus volume prior to stereotactic radiosurgery. […] The ultimate goal of intervention is to obliterate the AVM nidus and all arteriovenous shunt locations. […] The risk of perioperative morbidity and mortality increases with increasing Spetzler-Martin grade. […] AVMs smaller than 3cm in diameter with deep draining veins within the eloquent cortex are ideal for stereotactic radiosurgery as the morbidity and mortality of open surgical resection of these lesions are the highest. […] The complications of SRS for AVM treatment include seizure and hemorrhage. […] The prognosis of an intracranial AVM is dependent on a history of rupture. Unruptured AVMs have a 2.2% annual risk of rupture, and previously ruptured AVMs have a 4% annual risk.

  Surgery is the most common treatment for brain AVMs. […] Surgical removal, known as resection. Surgery may be recommended if the brain AVM has bled or is in an area that can easily be reached. […] Endovascular embolization is less invasive than traditional surgery. It may be performed alone but it’s often used before other surgical treatments to make them safer. It does this by reducing the size of the brain AVM or the likelihood of bleeding. […] Stereotactic radiosurgery (SRS). This treatment uses precisely focused radiation to destroy the AVM. This type of surgery doesn’t require cuts in the body the way other surgeries do. […] Sometimes healthcare professionals decide to monitor a brain AVM rather than treating it. This may be recommended if you have few or no symptoms or if your AVM is in an area of your brain that’s hard to treat. Monitoring includes regular medical checkups with your healthcare team. […] Ongoing advances in embolization, radiosurgery and microsurgery techniques also are making it possible to use surgery to treat brain AVMs that were hard to access in the past. Advances also are making it safer to remove brain AVMs during surgery.

  CNS vascular malformation is an umbrella term that encompasses a wide variety of pathologies, with a wide range of therapeutic and diagnostic importance. […] Advances in neurovascular imaging along with increased utilization of these advances, have resulted in more frequent identification of these lesions. […] In this review, we will outline epidemiological, clinical, radiological, and therapeutic features of intracranial and spinal cord vascular malformations and discuss syndromes associated with CNS vascular malformations. […] Understanding the pathophysiology, natural history, and characteristics predictive of the risk of rupture are all essential for clinicians when making appropriate therapeutic decisions. There are two main branches of therapy intervention or medical management. Medical management, or observation, includes treating risk factors for rupture such as hypertension and smoking cessation, and treating symptoms of the lesion itself, including headache and seizures. Surgical and radiologic interventions include endovascular therapy, surgery, and radiotherapy alone or in combination.

  Treatment options depend on your type of AVM, its location, noticeable symptoms, and your general health. […] Whenever an AVM is detected, the individual should be carefully and consistently monitored for any signs of instability 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 to individuals largely on a case-by-case basis.

  The choice of therapy is based on the appearance and symptoms of the particular venous malformation and can therefore be different over the course of a life. Complete removal is usually not possible. The starting point of treatment is a comprehensive assessment of the vascular malformation by the physician and detailed consultation of the affected person. Only then can a strategy be agreed upon and, depending on the extent of the venous malformation, this should be pursued throughout the individuals lifetime. […] Although smaller venous malformations can be adequately treated by one invasive treatment, a large number of patients require repeated treatments. Patients are often young play a central role because over time they get to know their body, their very specific malformation and the effects of the therapy methods. The more extensive the malformation is, the more important it is that the patient takes an active role in determining therapeutic steps.
