Aim:
A ruptured abdominal aortic aneurysm (rAAA) remains a significant threat to life, with a 30-50% in-hospital mortality rate. The recent introduction of emergency endovascular aneurysm repair (rEVAR) in New Zealand presents an alternative to open repair for rAAAs. The aim of this paper is to review the current experience in New Zealand in the repair of rAAAs.
Methods:
Data from the Australasian Vascular Audit (AVA) was reviewed, with data pertaining to rAAAs collected for the five-year period from January 2010 to December 2014.
Results:
Two hundred and eighty-five rAAAs were reported over the five-year period, with an overall mortality rate of 34.0%. There was no significant difference in in-hospital mortality rates alone after rEVAR vs open repair (rOR) (OR 0.39, 95% CI 0.14-1.06, P=0.065). Significant reductions in length of hospital stay (9.710.2 days vs 16.812.9 days, P=0.0125) and the combined in-hospital mortality/post-operative complication rate (35.7% vs 63.6%, OR 0.3, 95% CI 0.1-0.7, P=0.005) were observed after rEVAR vs rOR.
Conclusion:
A primary rEVAR approach is appropriate in selected patients and may represent a paradigm shift in the management of ruptured AAAs in New Zealand.
