The purpose of this multicenter study was to assess the long-term outcome of endovascular treatment of isolated @entity731 of the infrarenal abdominal aorta on the basis of clinical and ultrasound examination. Clinical, ultrasound, and angiographic findings from 36 @entity1 and 50 @entity1 (mean age, 53.2 years) treated for @entity731 of the infrarenal abdominal aorta were reviewed. @entity1 had @entity613 in 74 cases and @entity158 in 4. Seven @entity1 presented trophic manifestations and one had @entity9971 . Mean preoperative systolic index was 0.71. Mean diameter reduction was 77%. Circumferential calcification was partial in 36 cases (41%) and complete in 30 cases (35%). Percutaneous transluminal angioplasty was performed using the single-balloon technique in 60 cases and double-balloon technique in 26 cases. A stent was placed in 76 cases (88%) by necessity in 34% of cases (22 residual stenoses, 4 dissections). Completion angiographic findings were considered good in 82 cases (95%). The remaining four @entity1 had residual stenosis with a diameter reduction >30%. One @entity1 died during the immediate postoperative period from septicemia unrelated to treatment (early mortality, 1.2%). Aortic angioplasty was complicated by stent detachment from the angioplasty balloon in two @entity1 , retroperitoneal @entity1410 in one, @entity1897 in two, puncture-site @entity1410 in three, @entity583 in one, and @entity2268 of deep femoral artery in one @entity1 (early morbidity, 9.3%). All @entity1 underwent follow-up with clinical and hemodynamic evaluation (mean follow-up, 31 months). Actuarial survival at 3 years was 91%. Primary actuarial patency was 94% at 1 year, 89% at 3 years, and 77% at 5 years. @entity2333 occurred in seven @entity1 and was treated by angioplasty in two, aortobifemoral bypass in four, and surveillance in one. Mean systolic index was 0.89. Statistical analysis of patency demonstrated no factor predictive of long-term complication. From the long-term follow-up findings in this study, we conclude that aortic angioplasty is a reliable minimally invasive technique for treatment of isolated @entity731 of the infrarenal abdominal aorta.
