随着低侵入性成像工具的广泛使用，如磁共振血管造影和计算机断层扫描血管造影，未破裂的脑动脉瘤比过去更常见。本回顾性研究旨在确定未破裂颅内动脉瘤患者手术干预的危险因素。METHODSOVER 5年期间，1,558例颅内动脉瘤患者在我们中心接受了手术。在310例未破裂动脉瘤患者中，292例（95%）预后良好，仅1例（0.3%）巨大椎动脉瘤患者死亡。动脉瘤尺寸大于15 mm和动脉瘤位于后循环是与不良结局相关的独立风险因素。单一动脉瘤的患者有一个更好的结果比患者多aneurysm. CONCLUSION我们的结果支持的论点，未破裂的颅内动脉瘤的手术治疗进行了低风险的发病率和死亡率，并可能改善患者的结果窝藏脑动脉瘤，防止蛛网膜下腔出血的破坏性影响。动脉瘤大小、位置和数量是未破裂动脉瘤患者手术发病率的风险预测因素。(C)2000年，Elsevier Science Inc.
BACKGROUNDWith the widespread use of less invasive imaging tools, such as magnetic resonance angiography and computed tomographic angiography, unruptured cerebral aneurysms are found much more often than in the past. This retrospective study was undertaken to determine the risk factors for surgical intervention in a patient with an unruptured intracranial aneurysm.METHODSOver a 5-year period, 1,558 patients with intracranial aneurysms underwent surgery at our center. Of these, 310 patients (20%) with unruptured aneurysms were included in this study.RESULTSOut of 310 patients with unruptured aneurysms, 292 (95%) had a favorable outcome, and only one patient (0.3%) with a giant vertebral artery aneurysm died. Aneurysm size larger than 15 mm and location of the aneurysm in the posterior circulation were independent risk factors associated with less favorable outcomes. Patients with a-single aneurysm had a better outcome than did patients with multiple aneurysms.CONCLUSIONOur results support the contention that surgical treatment of unruptured intracranial aneurysms carries a low risk of morbidity and mortality and may improve the outcome in patients harboring cerebral aneurysms by preventing the devastating effects of subarachnoid hemorrhage. Aneurysm size, location, and number were risk predictors for surgical morbidity in patients with unruptured aneurysms. (C) 2000 by Elsevier Science Inc.
