Endovascular repair for ruptured AAA: a literature review

The reduced physiological impact of endovascular aneurysm repair (EVAR) compared with conventional open repair has been demonstrated. If this technique could be used routinely in patients with ruptured abdominal aortic aneurysm (AAA) it may reduce the high peri-operative mortality. This review of the literature identified the current experience with EVAR of ruptured AAA. Only a small number of case series with selected patients are reported. These patients were selected for their haemodynamic stability, and their suitable aneurysm morphology. The overall anatomic suitability rates for EVAR reported, suggest an applicability of 58% to 80% from an intent-to-treat experience. The average post-operative mortality rate was 24%, ranging from 9 to 45% and may reflect increasing experience and patient selection. Important lessons have been learned from these first experiences that help to define a clear position of EVAR as an additional therapeutic option for ruptured AAA.
