Impact of Aneurysm Projection on Intraoperative Complications During Surgical Clipping of Ruptured Posterior Communicating Artery Aneurysms.

摘要: Background Surgical clipping of ruptured posterior communicating artery (PCoA) aneurysms is a well-established procedure to date. However, preoperative factors associated with procedure-related risk require further elucidation. Objective To investigate the impact direction aneurysm projection on incidence complications during surgical PCoA aneurysms. Methods A total 65 patients who underwent were retrospectively analyzed from single-center, prospective, observational cohort database in this study. The categorized into lateral and groups, depending dome. Characteristics operative findings each group identified. We also evaluated any correlation complications. Results Patients more likely presented good-admission-grade subarachnoid hemorrhage (P = .01, χ test) less have intracerebral hematoma .01). These found be higher intraoperative rupture .02), complex fenestrated clips dense adherence or its perforators .04) by univariate analysis. Aneurysms correlated complications, including postoperative cerebral infarction formation (odds ratio, 5.87; 95% confidence interval, 1.11-31.1; P multivariable Conclusion Ruptured carried than those projection.
