【摘要】 目的 探讨血管内治疗颅内动脉瘤围手术期并发症的原因及护理对策。 方法 对2007年3月-2011年1月收治的365例采用血管内治疗动脉瘤患者中22例围手术期出现并发症者的临床资料进行回顾性分析。 结果 22例患者围手术期出现并发症，占6%。动脉瘤破裂再出血6例，其中发生于术前2例，术中3例，术后1例；脑血管痉挛 10例；脑血管血栓形成 4例，穿刺部位血肿 2例。 结论 血管内治疗颅内动脉瘤围手术期，采取预见性护理措施预防及观察主要并发症的发生和正确处理并发症，可降低其病死率和致残程度。【Abstract】 Objective To study and discuss the reasons for and clinical nursing of perioperative complications for patients undergoing endovascular treatment for intracranial aneurysms. Methods Twenty-two of 365 aneurysm patients who had undergone endovascular treatment between March 2007 and January 2010 in our hospital had perioperative complications. We retrospectively analyzed their clinical data. Results Twenty-two patients had perioperative complications, accounting for about 6%. The aneurysm was ruptured in 6 cases, which occurred before surgery in 2 patients, during the surgery in 3, and after the surgery in 1. There were 10 cases of cerebrovascular spasm, 4 cases of cerebrovascular thrombosis, and 2 cases of puncture site hematoma. Conclusion During the perioperative period of endovascular treatment for intracranial aneurysms, prognostic prevention measures, observation of the occurrence of major complications and proper management of complications can effectively reduce mortality and the degree of disability.
