前交通动脉瘤破裂因素分析

目的:研究前交通动脉瘤的破裂因素,以提高临床诊治的疗效。方法:回顾性总结近年来经CTA及动脉瘤夹闭术确诊证实的110例破裂前交通动脉瘤,分析其破裂因素。结果:110例前交通动脉瘤患者中,男49例,女61例,男女比0.8∶1,年龄17~77岁,平均49.3岁。CTA提示,110例前交通动脉瘤患者中大脑前动脉A1优势征63例(57.2%),其中左侧A1优势征46例,右侧A1优势征17例;大脑前动脉A1对称47例(42.8%)。另外,110例前交通动脉瘤患者中已诊断为高血压的58例(53%),血压正常的52例(47%)。结论:大脑前动脉A1优势征及高血压等先天性及后天性因素与前交通动脉瘤的破裂有密切的关系。

Analysis on ruptured factors of anterior communicating artery aneurysms

Objective To explore ruptured factors of anterior communicating artery aneurysms （ACoAA） and improve effects of diagnosis and management. Method We retrospectively analyzed 110 patients with anterior communicating artery aneurysms, which were proved by CTA and surgery recently years,to study the ruptured factors of ACoAA. Results First,CT angiography（CTA） results showed that of the 110 patients, 49 patients were male,61 patients were female and the proportion between them was 0. 8： 1. The ages of them from 17 to 77 years and the average age was 49.3 years. Second,of the 110 cases who had ACoAA,63 cases（57.2% ） presented the dominance of A1 segement ,of which 46 cases on the left side, 17 cases on the right side ,and 47 （42. 8% ） cases presented A1 symmetry. Moreover,of these 110 patients ,58patients（ 53% ） had diagnosed hypertension, and 52 patients （47%） had normal blood pressure. Confusion It was closeconnection that the congenital and postnatal factors including the dominance of Al segement and hypertension led to ruptured anterior communicating artery aneurysms.
