Abstract
ObjectiveBlood blister-like aneurysm (BBA) is a kind of dorsal wall aneurysm and it is small, sessile, fragile and hazardous because of its high mortality and morbidity. Many challenges tried to establish the management or strategy. But so far, there is no optimal treatment of choice for the BBA. In this article, 17 cases of the ruptured BBA in one institute were analyzed retrospectively. The operative options were correlated with surgical and clinical outcomes.Materials and MethodsDuring 14 years between October, 2002 and October, 2016, 23 patients were treated for subarachnoid hemorrhage with ruptured dorsal wall aneurysms. There were various strategies for treatment and different outcomes revealed. BBA were 17 (74%) cases and 6 (26%) cases were saccular aneurysm. By excluding saccular aneurysm, BBA was sorted and classified with its morphological characteristics, and the outcome of treatment in each case investigated retrospectively.ResultsAmong 17 BBA-cases, 8 cases get microsurgical operation by Sundt clip. 5 cases get operation by conventional Yasargil clip, 1 case treated by Yasargil clip with wrapping, and 2 cases underwent endovascular management with coiling, and 1 case was managed by endovascular trapping of involved internal cerebral artery. Clinical outcomes were analyzed with modified Rankin Scale, Glasgow outcome scale and post-operative complications.ConclusionAs the optimal management, operation using Sundt clip had much significance in treatment BBA. And, a thorough analysis of the angiography is essential to prepare for the treatment of BBA.
