Endovascular Treatment of Acute Abdominal Aortic Aneurysm with a Bifurcated Stentgraft

Abstract

Objectives

To analyse the results of emergency endovascular aneurysm repair (eEVAR) for acute abdominal aortic aneurysms (AAA), in comparison to open repair, and to evaluate suitability and application rate.

Patients and methods

All patients treated for an acute AAA between January 1998 and August 2004 were included. The primary outcome measure was in-hospital mortality. Secondary outcome measures were procedure time, intra-operative blood loss, transfusion requirement, intensive care unit, and hospital length of stay. Suitability and application rate for eEVAR were assessed in a subgroup of patients, from January 2003.

Results

A total of 253 patients were treated. eEVAR was performed in 40 patients, 5 (13%) died in-hospital. Open repair was performed in 213 patients, 64 (30%) died in-hospital. Secondary outcome measures were all significantly improved in the eEVAR subgroup.

From January 2003, 56 patients were treated. Of the 44 (79%) patients who were evaluated for eEVAR, 16 (36%) patients were anatomically suitable. Eventually, 15 out of the 56 (27%) patients were treated by eEVAR.

Conclusion

The results of eEVAR in a selected group of patients are promising, but suitability and application rate were low.
