Microsurgery for Intracranial Aneurysms (a Report of 302 Cases)

Objective To summarize the experience in treating intracranial aneurysms by microsurgery. Method The clinical data of 302 patients with intracranial aneurysms treated in our department from October, 1994 to May, 2006 were analysed retrospectively. Results Of 302 patients with intracranial aneurysms, 252 were treated by clipping aneurysmal necks, 19 by removing body after clipping the aneurysmal necks, 24 by coating the aneurysm and 7 by trapping the aneurysm. There were good outcome in 258 patients (85.4%), bad in 25 (8.3%) and 19(6.3%) died. Conclusions The operation should be performed as early as possible once the aneurysm is found. They are the key to the successful microsurgery to open cerebral cistern fully and to clip aneurysm neck correctly. The disabled and death rates may be decreased by positive prevention of cerebral vasospasm.
