Objective To summarize our experience on the endovascular treatment of pseudoaneurysm of abdominal aorta.Methods From January 2011 to November 2012, 9 patients[7 men; mean age (66.7±11.0) years, range 43-78] came to our department because of abdominal aortic pseudoaneurysm.Carefully analysis of the images before the operation was necessary, and the stent-graft was implanted totally percutenously or by femoral incision.20 stent-grafts were implanted successfully in 9 abdominal aortas(1 with fenestration stent-graft, 5 with unibody bifurcated stent-graft, 3 with tube stent-graft).Follow-up CTA was performed at approximately 1、 3 、 6 and 12 months to observe whether there is endoleak or complete thrombosis.Results Stent-grafts were implanted successfully for all patients.The technical success rate was 100.00%(n=9).Perioperative mortality was 0%(n=0).Follow-up ranged from 1 month to 23 months.One patient was converted to surgery because of recurrent infection of abdominal aorta and another died of respiratory failure 5 months postoperative during follow-up.Complete thrombosis of the aneurysm occurred in all the other patients.Mortality and morbidity during follow-up was 11.1% (1/9) and22.2% (2/9).Conclusion It is safe and effective to perform endovascular repair for pseudoaneurysms of the abdominal aorta, which presents with good short-term result.
