Improving outcomes for patients with ruptured abdominal aortic aneurysms (rAAA) remains a challenging paradigm despite the utilisation of rapid emergency medical transport systems and the development of improved intraoperative anaesthetic and surgical techniques.


To analyse the incidence of rAAAs and to compare mortality associated with open versus endovascular repair.


A retrospective analysis of patients presenting with rAAAs between January 2010 and March 2018 was conducted using data from the Australasian Vascular Audit (AVA). Patients who did not undergo a procedure, had a suprarenal, mycotic or isolated iliac aneurysm, or had a previous repair were excluded.


52 patients were identified, of which 87% were male with a mean age of 78.3 years. There were 7 deaths of which 14% had IHD, 71% had hypertension, 57% were ex-smokers and no patients were recorded to have a history of diabetes. 19 patients (37%) underwent open repair, 31 (60%) successful endoluminal repair and 2 (4%) required conversion to open repair. Mortality was 26%, 13% and 100% respectively. The median (IQ range) diameter was 8.0 cm (6.09.0) and in the three groups 8.5 cm (7.39.0), 7.0 cm (6.08.0) and 9.0 cm (8.59.5) respectively. Seven rAAAs were less than 6 cm in diameter.


Patients undergoing endoluminal repair for rAAA had significantly better survival than those undergoing open repair (P = 0.035). The mean diameter of rAAAs is higher than the threshold diameters usually suggested for elective repair. With rAAA still associated with a high morbidity and mortality, a protocol is being formulated at Royal North Shore Hospital to ensure expediated surgical intervention.
