BACKGROUND
Final events preceding aneurysm rupture are not completely known. The current study relates to incomplete aortic aneurysm wall lesions (i.e. malacia, dark staining and blebs or blisters) as possible sites of aneurysm rupture.
METHODS
162 abdominal aortic aneurysms, resected between 1988 and 1996, have been reviewed and 27 cases of aneurysms presenting wall thickness lesions are reported. The lesions were scheduled by operative reports and compared to ultrasound and CT scans.
RESULTS
The authors classify aortic aneurysms into three phases, depending on the degree of wall degeneration viz 1. Flawless wall aneurysms. 2. (a-b-c) Aneurysms with intraparietal lesions. 3. Ruptured aneurysms.
CONCLUSIONS
It is concluded that stage 2 aortic aneurysms must be urgently operated on. They carry a high surgical risk and, consequently, higher morbidity and mortality compared with stage 1 aneurysms.
背景
动脉瘤破裂前的最终事件尚不完全清楚。当前研究涉及不完全性主动脉瘤壁病变（即软化、深色染色以及小泡或水泡），将其视为动脉瘤破裂的可能部位。
方法
回顾了1988年至1996年间切除的162例腹主动脉瘤，并报告了27例出现壁厚病变的动脉瘤病例。根据手术报告对病变进行分类，并与超声和CT扫描结果进行比较。
结果
作者根据壁退变程度将主动脉瘤分为三个阶段，即1. 无缺陷壁动脉瘤。2. （a - b - c）伴有壁内病变的动脉瘤。3. 破裂动脉瘤。
结论
得出的结论是，2期主动脉瘤必须紧急进行手术。与1期动脉瘤相比，它们具有较高的手术风险，因此发病率和死亡率更高。
