We have treated 43 ruptured aneurysms in 42 patients with Guglielmi Detachable Coils (GDC) in acute period. Thirty-one patients (74%) were independent on discharge. Among the patients of Hunt and Hess Grade I, II and III, 27 patients (84%) were independent. Acute rerupture occurred in two elderly patients with insufficient embolization and another patient experienced rerupture 45 days after the embolization. Symptomatic vasospasm was reported in 16% of patients and its permanent morbidity rate resulted in 3.1%. Although the long term results remain to be determined, embolization with GDC is a safe and promising treatment for acutely ruptured aneurysms.
