Clinical features of ruptured middle cerebral artery aneurysm and endovascular embolization therapy

Objective To summarize clinical features of middle cerebral artery aneurysms and the techniques and treatment effect of endovascular embolization with Guglielmi detachable coils(GDC).Methods A total of 32 cases with middle cerebral artery aneurysms were treated with GDC to embolize the aneurismal sac via femoral artery approach.Early intervention of hemorrhage was performed post-operation.Results All 32 patients were cured,in which 30 cases recovered clinically and 2 patients died.The mortality was 6.3%.The 100% embolization were achieved in 27 sacs of aneurysms,95% embolization in 3,and 90% embolization in 2.Aneurysms had not ruptured during the embolization.Cerebral vasospasm happened in 4 cases and cerebral infarct in 1 case.One case of recurrence was cured by second GDC embolization.The technique-related complications presented in 4 cases.No re-bleeding occurred during the follow-up of 3 to 72 months.Conclusion The endovascular embolization is a safe and effective treatment for the middle cerebral artery aneurysms.Early embolization of aneurysms and efficient treatment in post-operation are the important methods to improve the curative rate.
