Cerebral Vasospasm after Surgical Clipping Versus GDC Embolization in Ruptured Intracranial Aneurysm

Objective : The purpose of this study is to analyze the influence of the treatment modality(surgical cilpping versus GDC embolization) on development of cerebral vasospasm in a non-randomized retrospective analysis of 93 patients of aneurysmal subarachnoid hemorrhage. Methods : The following parameters were retrospectively reviewed in our institution's data base and analyzed in association with vasospasm-related ischemic infarctions : 1) Hunt and Hess(H&H) grade, 2) Fisher group, 3) location of aneurysm, 4) treatment modality(surgical cilpping versus endovascular treatment). Results : Of the 93 patients, 39 (41.9%) patients suffered delayed ischemic infarctions. The incidence of delayed ischemic infarctions were increased as higher H&H grade and Fisher group but was not related with the location of aneurysms and the treatment modalities. Conclusion : Even with vigorous removal of the subarachnoid blood clots in the surgical clipping group, there is no statistical differences in the incidence of cerebral vasospasm between the two treatment modalities.
