Comparative Study of Cerebral Vasospasm between Endovascular Treatment and Conventional Surgery of Acutely Ruptured Aneurysms: Clinical Study / 대한뇌혈관외과학회지

ABSTRACT

OBJECT Generally, it seems like that the incidence of vasospasm of vasospasm in endovascular coil embolization is higher than clipping in aneurysmal subarachnoid hemorrhage. But endovascular coil embolization in our study group was not associated with higher incidence of symptomatic vasospasm than direct clipping and we made an analysis of that cause. METHODS: The authors reviewed 220 patients with aneurysmal subarachnoid hemorrhage who had been treated with either neck clipping or coil embolization by a single surgeon between January 1997 and December 2002. Poor initial grade (Hunt & Hess grade IV & V) patients were excluded. Finally 171 patients were enrolled in this study. 126 patients(74%) underwent direct surgical clipping and 45 patients (26%) underwent endovascular treatments of their aneurysms. RESULTS: Overall symptomatic vasospasm occurred in 32 (19%) patients, 4 of 45 patients (9%) were coiling group and 28 of 126 (22%) were surgically treated group. There was no difference between two groups in age, initial Hunt & Hess grade, Glasgow coma scale, operation time, treatment initiation time, patient's medical status. CONCLUSIONS: Patients who underwent coil embolization were not more likely to suffer from symptomatic vasospasm than aneurysm neck clipping in better clinical grades (Hunt & Hess grade of I to III) patients in our institute.
