ABSTRACT
<p><b>OBJECTIVE</b>To evaluated the feasibility, efficacy, and outcome of endovascular repair for descending aortic pseudoaneurysms.</p><p><b>METHODS</b>From April 2007 to November 2010, 20 patients of descending aortic pseudoaneurysm were treated. There were 18 male and 2 female, aged from 28 to 82 years with a mean of (58 ± 16) years. In this group, 4 patients were diagnosed as Behçet's syndrome, 6 patients as mycotic pseudoaneurysms with positive blood culture, 6 patients as suspected mycotic pseudoaneurysms, 1 patient with iatrogenic pseudoaneurysm and 1 patient with chronic grain-mononuclear cell leukemia, the other 3 patients with unknown reasons. The 88.5% of aortic pseudoaneurysms were located at abdominal aorta. Fifteen patients underwent endovascular therapy and 2 patients were treated by traditional open surgery. The other 3 patients underwent conservative treatments. The data of treatments and follow-up in the 15 patients who received endovascular repairs were retrospectively analyzed.</p><p><b>RESULTS</b>Endovascular therapy was performed successfully on the 15 patients, and the technique successful rate was 15/15. Total 15 stents were transluminal placed including 6 bifurcate stent-grafts, 6 abdominal straight stent-grafts, 2 thoracic straight stent-grafts and 1 abdominal bare stent. One patient was treated by stent assisted embolization. Perioperative mortality rate was 0. Only 2 primary type IV endoleaks were found. Fourteen patients were successfully followed up. During a mean follow-up of 538 days, 8 (57.1%) patients were uneventful. Six (42.9%) patients were complicated by aneurysm related events, including 4 (28.6%) aneurysm-related deaths, 1 (7.14%) with delayed endoleak and 1 (7.14%) with recurrent pseudoaneurysm which was retreated by another stent-graft.</p><p><b>CONCLUSIONS</b>Endovascular therapy for descending aortic pseudoaneurysms is a feasible and mini-invasive option with high technique success rate and low perioperative mortality rate. However, risk of recurrence and rupture to death of pseudoaneurysm remains high during follow-up. Treating the underlying reasons and intensively follow-up may be good for improving the prognosis of descending aortic pseudoaneurysms treated by endovascular therapy.</p>
