Abstract：Objective To assess the curative effects of microsurgical clipping on the blister-like aneurysms(BLAs)of the internal carotid artery (ICA). Methods The clinical data of 15 patients with 16 BLAs of the supraclinoid ICA, who underwent microsurgical clipping under elctrophysiological monitoring from January, 2012 to June, 2016, were analyzed retrospectively, including the clinical characteristics,radiological features,and intraoperative findings.The treatment strategies were discussed.The prognoses in the patients were assessed by the modified Rankin scale(mRS) 1 year after the surgery. Results Morphologically, aneurysm growth before surgery occurred in two ruptured and one unruptured BLAs.A daughter bleb formation was observed on angiographic images in every one of two ruptured and five unruptured BLAs.Varied range of sclerosis on the supraclinoid segment of ICA existed in 9 patients.Sixteen BLAs were successfully occluded in 15 patients. The following-up 1 year after the surgery showed that of 15 patients 13 had favorable outcomes(mRS 0 score)and 2 unfavorable outcomes(mRS 3 and 5 scores respectively).Conclusions It is more likely that ruptured and unruptured BLAs have different evolving processes.Microsurgical clipping is relatively a concise and feasible method to treat ICA BLAs, and can bring good outcomes to most patients with ICA BLAs.However,it is extremely difficult and dangerous to adopt direct clipping, and an appropriate alternative solution should be determined in the ICA BLAs patients with severely atherosclerotic parent artery wall.
