大脑前动脉A_1段动脉瘤的临床特点及治疗(附8例分析)

Clinical characteristics and treatment of aneurysms arising from anterior cerebral artery A_1 segment

目的探讨大脑前动脉A_1段动脉瘤的临床特征以及治疗方式。方法回顾性分析2010年1月至2014年3月收治的8例大脑前动脉A_1段动脉瘤的临床资料。结果蛛网膜下腔出血6例,未破裂2例;栓塞治疗4例,夹闭4例。术后随访12~36个月;6例可正常工作生活,2例生活基本能够自理;改良Rankin量表评分2分2例,1分2例,0分4例;8例DSA或CTA复查均未见复发。结论大脑前动脉A_1段动脉瘤破裂可主要表现为蛛网膜下腔出血,血管内栓塞治疗及显微夹闭术均是可行并有效的治疗方法。

Objective To explore the clinical characteristics and treatment of intracranial aneurysm arising from anterior cerebralartery(ACA) A_1 segments.MethodsThe clinical data of 8 patients with ACA A_1 segment aneurysms confirmed by cerebral DSA wereanalyzed retrospectively, including clinical and imaging characteristics, therapeutic method and so on.ResultsOf 8 patients with A_1 segment aneurysms, 6 had subarachnoid hemorrhage and 2 not. Four patients were treated by endovascular embolization and 4 bysurgery. All the patients had good curative effects.ConclusionsThe mainly clinical manifestation of the intracranial aneurysm arisingfrom ACA A_1 segment is SAH. DSA is the golden standard of diagnosis of A_1 segment intracranial aneurysms, which can be treated byendovascular embolization or microsurgery. The curative effects of endovascular embolization and microsurgery on A_1 segmentaneurysms are good.
