Superior Temporal Gyrus Approach to Middle Cerebral Artery Aneurysms

Authors experienced 36 cases of middle cerebral artery aneurysms in 35 patients. Among 36 cases, M1 aneurysms were 4 cases, M1 bi-or trifurcation aneurysms 30 cases, and distal aneurysms 2 cases. The majority of M1 bi-or trifurcation aneurysms were operated upon by the superior temporal gyrus approach. Trans-sylvian approach was used only in M1 aneurysms, in cases of short M1, in associated anterior circulation aneurysms, and in second operation to the unruptured middle cerebral artery aneurysms. Our results were encouraging. Mortality was 5.6%, and morbidity was also 5.6%.
