| Popis: | We sought to assess the effectiveness of endovascular abdominal aortic aneurysm (AAA) repair (EVAR) through a retrospective review of 6 years' experience at a single centre.From April 2005 to August 2011, 222 patients affected by abdominal aortic aneurysms underwent EVAR. We evaluated primary technical success, postprocedural mortality, intraprocedural and postprocedural complications with contrast-enhanced computed tomography (CT) and contrast-enhanced ultrasound (US) follow-up at 1, 6 and 12 months and annually thereafter.The procedures were elective in 75.7% and urgent due to symptomatic or ruptured aneurysm in 24.3%. Technical success was 98.6%; three patients (1.4%) required conversion to open surgery. Postoperative mortality rate was 24% for urgent and 2.3% for elective procedures. During a mean follow-up period of 29.6 months, no cases of stent-graft migration were observed; the overall incidence of endoleaks was 27% (60/222) and comprised four type I (1.8%) and one type III (0.45%), all treated by stent-graft extension, and 55 type 2 (24.8%), eight of which (14.5%) were treated by percutaneous injection of thrombin. In 10/222 cases (4.5%), thrombotic occlusion of the iliac extension was detected, which was successfully treated by transcatheter intra-arterial thrombolysis. One patient developed stent-graft infection requiring surgical explantation. Average hospital stay was 4 days, and average time in intensive care was 2 days.Consistent with the literature data, our study confirms the safety and long-term efficacy of EVAR for treating AAA. |
