  Moymoya is treated with surgery to fix the narrowed arteries in the brain and decrease the risk of stroke. While surgery is the only viable treatment for moyamoya disease in the long term, your doctor may also recommend medication to manage some of your child’s symptoms. These may include aspirin (to help prevent blood from clotting) and calcium channel blockers, such as verapamil (to help lower blood pressure). […] Several surgical treatments for moyamoya are effective at bypassing narrowed arteries and creating a new blood supply for the affected areas of the brain. […] There are several types of surgical treatments for moyamoya: […] Pial synangiosis. This is a type of surgery that reroutes the healthy scalp blood vessel to the brain, bypassing the narrowed vessels. […] EDAS (encephaloduroarteriosynangiosis). In this procedure, the superficial temporal artery in the child’s brain is laid over an opening in the cortex. The artery is then sewed to the dura (the firm layer of tissue that covers the brain). Over time, small new arterial vessels begin to develop.

  It is important to keep in mind that there is no curative treatment for moyamoya disease. Early diagnosis of moyamoya disease coupled with timely surgical intervention is of utmost importance as medical therapies act only as secondary prevention and do not halt disease progression. Both, medical and surgical treatments are directed towards improving cerebral blood flow. Acute therapy for strokes and/or intracranial bleeding is performed as per standard protocols. […] Conservative management is mainly directed towards maintaining cerebral blood flow and preventing further strokes. Aspirin has been conventionally used among patients of moyamoya disease to prevent further strokes. However, there is no evidence of a potential benefit of antiplatelet use to stroke prevention since the mechanism of MMD does not involve an endothelial damage and thereby platelet adhesion. Nevertheless, many neurologists around the world use aspirin towards mitigating the chances of further strokes in light of other risk factors and as a maintenance therapy to prevent thrombosis and thromboembolism from the stenosed portion of vessels after surgical revascularization. The usual dose of 50-100 mg is recommended.

  Surgical moyamoya treatment consists of restoring blood flow to the brain with procedures known as revascularization procedures. There are two main types of revascularization procedures: direct and indirect. […] In a direct revascularization, the surgeon directly sutures a healthy extracranial blood vessel to an incision made in the wall of a blood-deprived intracranial vessel, giving the intracranial vessel a full blood supply. […] The main advantage of a direct revascularization is that the new blood supply is immediate. […] In an indirect revascularization, a surgeon places an existing blood supply on the surface of the oxygen-deprived region of the brain. […] EDAS and pial synangiosis are excellent options for pediatric moyamoya patients, and for adult patients who cannot undergo an EC/IC bypass.

  Revascularization surgery can restore blood flow to the brain, and decrease pressure on the moyamoya vessels. In these delicate procedures, specialized surgeons connect blood vessels on the outside and inside of the skull to bypass blocked arteries. […] Direct revascularization surgery. In this procedure, a blood vessel from the scalp (superficial temporal artery) is surgically attached to a brain blood vessel (middle cerebral artery), which immediately provides additional blood to the starved brain. […] Direct bypass is what we do for 99% of adult patients with Moyamoya disease, says Dr. Dehdashti. The procedure typically takes about four hours, and patients need to stay in the hospital for about three days after surgery. […] In children, however, direct bypass may be difficult due to the smaller size of their blood vessels.

  Surgical revascularization: This is the only main treatment for MMD with deteriorating cerebral hemodynamics to improve the cerebral blood flow and prevent further strokes. Main indications for surgical revascularization are apparent cerebral ischemia, reduced regional cerebral blood flow and decreased cerebral vascular reserve in perfusion studies. However, every case is evaluated separately as decisive factors may vary from case to case. Surgery is more beneficial for children since the pediatric form of MMD is usually rapidly progressive. […] Indirect revascularization: This is an easier method to perform but the time to improve the cerebral blood flow is longer than the direct revascularization. Major techniques used under this method are encephalomyo synangiosis (EMS) where the supply comes from the deep temporal artery and encephalo-duro-arterio synangiosis (EDAS) with the supply comes from superficial temporal artery. […] Direct revascularization: Superficial temporal artery is used as the main supply vessel in direct bypass. Direct vascularization is technically more difficult to perform and requires a highly skilled surgeon but the improvement in the cerebral blood flow is noted immediately following the surgery.

  Moyamoya disease is a rare cerebrovascular disease that occurs due to narrowing and blockage of the internal carotid arteries and their associated branches resulting in the development of additional collateral vessels. […] Endovascular techniques have emerged as a potential option for managing MMD, particularly for individuals who are unsuitable candidates for direct surgical revascularization or have already undergone such procedures. Various endovascular techniques, such as coiling, stenting, and angioplasty have been used in managing Moyamoya disease. […] Comparatively, embolization, particularly onyx embolization remains the gold standard for MMD treatment as it provides a more definitive and long-term solution by addressing MMD-associated complications with little to no adverse events. Overall, endovascular techniques showed varying results with some interventions being safer and more effective than others.

  Surgery is the preferred treatment for moyamoya disease. However drug therapy may be used as an alternative when surgery is not an option. […] The goal of surgery is to go around the blockage and allow new blood vessels to develop to bring blood and oxygen to the brain. With experienced neurovascular surgeons, such as those at Cedars-Sinai, the risks of this surgery generally are low and the long-term outlook for children who have been treated for the disease is good. […] Full recovery from surgery may take six to 12 months, though many patients see an improvement in their symptoms almost immediately. If a patient has had major bleeding into the brain, the damage may be permanent, and prompt treatment is important to preserve as much brain function as possible. […] Surgical procedures used to treat moyamoya disease include: Encephaloduroarteriosynangiosis (EDAS): This procedure requires freeing up, without severing, a scalp artery over a course of several inches and then making a small temporary opening in the skull directly beneath the artery. The artery is then sutured to the surface of the brain and the bone replaced.

  Moyamoya angiopathy (MMA) is a peculiar cerebrovascular condition characterized by progressive steno-occlusion of the terminal part of the internal carotid arteries (ICAs) and their proximal branches, associated with the development of a network of fragile collateral vessels at the base of the brain. […] The available treatment strategies are currently shared between idiopathic MMD and MMS, including pharmacological and surgical stroke prevention treatments and symptomatic drugs. […] Surgical revascularization techniques, which are currently the best available treatment in symptomatic MMA, are associated with good long-term outcomes and reduced ischemic and hemorrhagic risks. […] To date, no curative treatment allowing regression of the occlusive arterial lesions has been found for MMA.

  The surgical procedures are designed to help re-establish the blood supply to the brain by diverting the scalp blood supply to the brain surface and in that way bypass the progressive loss of brain hemisphere blood flow. […] Long-term results following surgery of either type have been quite good, with long-term prevention of strokes seen in published series of both pediatric and adult patients. […] The modified direct anastomosis and encephalo-myo-arterio-synangiosis play a role in this improvement by increasing cerebral blood flow (CBF) after the operation. […] The treatment results are usually permanent.

  Moyamoya is a progressive intracranial vasculopathy that can lead to neurologic complications due to impaired cerebral circulation, including ischemic stroke and intracranial hemorrhage. There is no curative treatment for moyamoya. However, supportive management may reduce the risk of complications, and imaging surveillance can help to identify patients who are at the highest risk for future ischemic and hemorrhagic complications and would benefit from surgical revascularization. […] Surgical revascularization for moyamoya is typically indicated both for patients who are symptomatic and for asymptomatic patients with neuroimaging findings suggestive of severe impairment of resting blood flow or impaired hemodynamic perfusion reserve. These patients are at high risk for future complications, and surgical revascularization may reduce the risk of subsequent morbidity. However, the final decision to pursue surgical revascularization for moyamoya depends on individual risks and benefits of surgery and patient values and preferences.

  If you have been diagnosed with Moyamoya disease, you should be evaluated by a neurosurgeon who specializes in this disorder. […] At MedStar Health, our Moyamoya disease specialist will carefully evaluate you and counsel you about the safest and most effective treatment. […] Bypass surgery, otherwise known as cerebral revascularization, allows more blood to be delivered to the brain. This significantly reduces the risk of stroke. […] Our Moyamoya disease specialist has expertise in the various kinds of bypass surgery and can determine the most appropriate one for you. […] One such procedure involves the use of microsurgical technique (using a high-powered microscope and specialized tools) to connect and sew an artery of the scalp to an artery of the brain. This allows the scalp artery to deliver blood to the brain, improving blood flow to the brain and reducing the risk of strokes. The procedure is called the STA-MCA bypass (superficial temporal artery to middle cerebral artery bypass) or EC-IC bypass (extracranial to intracranial bypass). […] During the STA-MCA bypass surgery, or STA-MCA anastomosis, the neurosurgeon connects the open end of a scalp artery to the sidewall of a brain artery. […] At MedStar Health, we successfully perform this procedure with expert microsurgical techniques and state-of-the-art specialized technology.

  Moymoya is treated with surgery to fix the narrowed arteries in the brain and decrease the risk of stroke. While surgery is the only viable treatment for moyamoya disease in the long term, your doctor may also recommend medication to manage some of your child’s symptoms. These may include aspirin (to help prevent blood from clotting) and calcium channel blockers, such as verapamil (to help lower blood pressure). […] Several surgical treatments for moyamoya are effective at bypassing narrowed arteries and creating a new blood supply for the affected areas of the brain. […] There are several types of surgical treatments for moyamoya: […] Pial synangiosis. This is a type of surgery that reroutes the healthy scalp blood vessel to the brain, bypassing the narrowed vessels. […] EDAS (encephaloduroarteriosynangiosis). In this procedure, the superficial temporal artery in the child’s brain is laid over an opening in the cortex. The artery is then sewed to the dura (the firm layer of tissue that covers the brain). Over time, small new arterial vessels begin to develop.

  EMS (encephalomyosynangiosis). In this procedure, small portions of the temporalis muscle in the jaw are attached in a parallel direction to the surface of the child’s brain. The transplanted muscle gradually generates new blood vessels, forming a supplementary source of blood flow to the brain. […] Omental transposition/transfer. In this procedure, the child’s omentum, the blood-rich lining that surrounds the organs in the abdomen, is laid over the surface of the brain. New vessels eventually develop and grow into the brain. […] Dural inversion. In this procedure, neurosurgeons invert the flaps of fibrous dural tissue on the child’s meningeal vessel, a large artery within the skull. This places the outer dural surface, which has plentiful blood vessels, in direct contact with the parts of the brain that were previously deprived of essential blood flow.
