“…The first successful anterior circulation microvascular extracranial-to-intracranial (EC-IC) bypass surgery was performed in 1967 1 and over the next 20 years several reports appeared docu-menting the ability of the procedure to result in long-term patency with low morbidity and mortality. [2][3][4][5][6][7][8][9][10] The history of diagnosis and management of posterior circulation ischemia parallels that of anterior circulation in terms of the development of pharmacological, endovascular, and surgical options. Low complication rates and excellent patency have also been reported for posterior circulation surgical revascularization, [11][12][13][14][15][16][17][18][19][20][21] as well as improvement of symptoms and regional cerebral blood flow (CBF) and a reduction of the risk of future strokes.…”

The primary objective of revascularization procedures in the posterior circulation is the prevention of vertebrobasilar ischemic stroke. Specific anatomical and neurophysiologic characteristics such as posterior communicating artery size affect the susceptibility to ischemia. Current indications for revascularization include symptomatic vertebrobasilar ischemia refractory to medical therapy and ischemia caused by parent vessel occlusion as treatment for complex aneurysms. Treatment options include endovascular angioplasty and stenting, surgical endarterectomy, arterial reimplantation, extracranial-to-intracranial anastomosis, and indirect bypasses. Pretreatment studies including cerebral blood flow measurements with assessment of hemodynamic reserve can affect treatment decisions. Careful blood pressure regulation, neurophysiologic monitoring, and neuroprotective measures such as mild brain hypothermia can help minimize the risks of intervention. Microscope, microinstruments and intraoperative Doppler are routinely used. The superficial temporal artery, occipital artery, and external carotid artery can be used to augment blood flow to the superior cerebellar artery, posterior cerebral artery, posterior inferior cerebellar artery, or anterior inferior cerebellar artery. Interposition venous or arterial grafts can be used to increase length. Several published series report improvement or relief of symptoms in 60 to 100% of patients with a reduction of risk of future stroke and low complication rates.

“…O tratamento medicamentoso do paciente com acidente vascular encefálico isquêmico (AVEI) está bem estabelecido [1][2][3] . Entretanto, existem situações em que, apesar do melhor manejo adotado, há recorrência do evento isquêmico 4,5 . Dentre estes, há casos de insuficiência vascular por obstrução total ou parcial de artérias calibrosas responsáveis pela irrigação encefálica que podem ser manejadas pela anastomose extraintracraniana (AEIC) [6][7][8] .…”

The extra-intracranial bypass may be used in selected cases of brain vascular insufficiency refractory to clinical treatment. We report a case of encephalic ischemia in the territory of the right middle cerebral artery due to occlusion of the ipsilateral internal carotid artery, with consequent reduction of the perfusion and vascular reserve in the parietal and frontal regions. Despite the clinical treatment, motor deficit improvement was directly related to the maintenance of high systemic arterial tension levels due to the use of vasopressor agent. After lateral-terminal extra-intracranial bypass between the superficial temporal and right middle cerebral artery, there was significant improvement of cerebral perfusion with remission of the motor deficit.
