Analysis of Clip-induced Ischemic Complication of Anterior Choroidal Artery Aneurysms

摘要: OBJECTIVE The surgical approach is typically similar to those used for other supraclinoid internal carotid artery (ICA) lesions. However, the clipping of this aneurysm complicated and as a result, can result in postoperative ischemic complications. We studied clarify clip-induced complication risk AChA get benefits helping decision making. METHODS retrospectively investigated 53 cases (4.0%) AchA treated surgically. divided 3 subtype according origin aneurysmal neck; A type originating from itself, J junction ICA, I ICA itself. evaluated brain CT about 1 week post-operative day confirm low density territory. RESULTS Ruptured was 26 unruptured 27 cases. A, J, 13, 17, 23 Of who performed neck clipping, twelve (22.6%) had distribution infarcts. Increased infarct after statistic significance non-I (p=0.005). CONCLUSION It easy classify "easy" surgery. But surgery aneurysms carries with it significant stroke. Don't always stick only, especially incidental small aneurysm, which has high post-clip
