动脉瘤被定义为附近正常血管直径两倍的凸起。当动脉壁变得过于脆弱而无法承受内部血压时，动脉瘤就会破裂。由血管外科医生进行紧急临床检查，如果时间允许，在修复前进行超声或CT血管造影检查，可能会挽救生命。在爱普沃斯皇家墨尔本医院及时修复的结果是90-95%的成功率，而一旦动脉瘤破裂，只有50%的患者能存活下来。
Aneurysms are defined as bulges twice the diameter of the nearby normal vessel. Aneurysms burst when the artery wall becomes too weak for the blood pressure within. Urgent clinical examination by a vascular surgeon, then an ultrasound or CT angiogram if time permits before repair, may save life. The result of a timely repair at Royal Melbourne Hospital of Epworth is 90-95% success, while only 50% of patients survive an attempt to repair the aneurysm once it has burst.
