Ruptured abdominal aortic aneurysm:: endovascular treatment

Background: This report describes our preliminary experience in endovascular management of 25 ruptured abdominal aortic aneurysms (rAAAs). Methods: In the past 3 years we treated 46 patients who had rAAA, and 25 (54.3%) were treated with an endovascular approach. Patients' mean age was 76 +/- 9 years. The diagnosis was confirmed by computed tomographic angiography in 23 patients (92%). Mean aneurysm diameter was 73 +/- 17 mm. We used an infrarenal bifurcated device in 17 patients (68%), a suprarenal bifurcated in four patients (16%), and an aortomonoiliac graft in four patients (16%). Overall, nine patients (36%) required intensive care. Every patient underwent radiologic follow-up according to the Eurostar register, with concomitant evaluation of the D-dimer level (cut-off <200 mu g/L) as a biological marker for endoleaks. Results: The primary technical success rate was 100%. Overall in-hospital mortality rate was 20%. Mean hospitalization was 7 days (range, 3-30), and mean follow-up was 7 months. One occlusion (4%) of the iliac limb and two type 11 endoleaks (8%) occurred. The mean D-dimer level in type I endoleak was 1045 mu g/L (range, 459-2021). Conclusions: In our experience, endovascular management of rAAA is feasible and safe and produces better results than conventional surgery, provided the morphology is suitable and the procedure is carried out by an experienced endovascular team.
