The purpose of this study is to report our early experience with endovascular treatment of patients with symptomatic non-ruptured (sAAA) or ruptured (rAAA) abdominal aortic aneurysms. Between September 2005 and September 2008, all patients with a diagnosis of sAAA or rAAA were evaluated for endovascular suitability. We did not consider hemodynamic instability to be a contraindication for endovascular aneurysm repair (EVAR). Patients whose aneurysm anatomy was not suitable for EVAR received open repair (OR). A total of 46 patients with sAAA or rAAA underwent emergency EVAR: in particular, 18/46 patients were treated for sAAA and 28/46 for rAAA. Successful stent-graft deployment was achieved in 44 patients (96%); we had two open surgical conversions. The 30-day mortality rate was 19.5%. Nine patients died during the first 30 postoperative days: four patients died within 24 hours because of severe hypovolemic shock, two died of respiratory failure, one died as a result of bowel ischemia and two because of myocardial infarction after hospital discharge. Complete follow-up data were available for 35 patients (median 185 days; range 30-730 days). In conclusion, endovascular treatment is feasible and the early experience is promising. The capability of offering EVAR and OR for sAAA and rAAA according to our experience suggests that EVAR and OR should be regarded as complementary techniques to improve outcome of patients with acute AAA.
