Middle cerebral artery revascularization: anatomical studies and considerations on the anastomosis site

Abstract: In the surgical management of skull base lesions and vascular diseases such as giant aneurysms, involvement of the internal carotid artery may require the resection or the occlusion of the vessel. The anastomosis of the external carotid artery and the middle cerebral artery with venous graft may be indicated to re-establish the blood flow. To determine the best suture site in the middle cerebral artery, an anatomical study was carried out. Fourteen cerebral hemispheres were analysed after the injection of red … Show more

“…If bifurcation occurs, the superior trunk typically gives rise to the OfA, prefrontal, precentral and central arteries. With the trifurcation pattern, the superior trunk usually gives rise to the OfA and prefrontal arteries, while the precentral and central arteries can originate from either the superior or the middle trunk (5,39,47,63,72,84).…”

“…A era das anastomoses microvasculares surgiu com o bypass da carótida externa/carótida interna, ACE-ACI, na forma dos shunts artéria-temporalsuperficial-artéria-cerebral-média , ATS-ACM, como proposto por Yasargil na década de 70 3,5 . Essas pontes anastomóticas, consideradas, mais tarde, de baixo fluxo, além de apresentarem predisposição à oclusão por trombose pelo fluxo lento 6 , não eram capazes de suprir o território vascular envolvido 2,3,4,6 , mais uma vez resultando em morbidade e mortalidade relacionada a eventos isquêmicos.…”

“…O enxerto utilizando a veia safena entre a circulação extracraniana e intracraniana foi realizado inicialmente para promover fluxo colateral de alto volume 1 em pacientes com doença cérebro-oclusiva avançada 6 , mais tarde se estendendo como alternativa viável na revascularização cerebral para o tratamento de aneurismas gigantes ou das lesões neoplásicas da base do crânio que requeriam a oclusão da carótida interna 5,6 . Esse tipo de anastomose, assim como os enxertos venosos utilizados em cirurgia cardiovascular, se correlaciona com maior índice de falha durante o primeiro ano após a cirurgia, 43% dessas falhas ocorrendo nas primeiras 24 horas.…”
