Safety and Efficacy of Surgical Treatment of Intracranial Aneurysms: The Experience of a Single Brazilian Center (original) (raw)

Nowadays, the use of microsurgery for clipping aneurysms has decreased considerably. To demonstrate the safety and effectiveness of surgical treatment of intracranial aneurysms even in less developed countries. Retrospective review of the medical records of 320 patients with 416 aneurysms treated with microsurgical clipping from 2008 to 2016 in a single neurosurgical center in Brazil. This study evaluated postoperative outcome, using the modified Rankin Scale (mRS) on hospital discharge, treatment efficacy, assessed by digital subtraction angiography (DSA) performed postoperatively, and mortality. Among 320 patients with aneurysms, 228 patients presented with ruptured aneurysms and 92 patients with unruptured aneurysms. Overall, 81 (26,3%) presented poor outcome (mRs>2) while 227 (73,4%) showed good outcome. The presence of a ruptured aneurysm was a statistically significant factor for poor outcome (p<0,001) and mortality (p<0,015). Giant and large aneurysms were also assoc...
