title: Primary endovascular stent placement for focal infrarenal aortic stenosis: initial and midterm results.
abstract: The objectives of this retrospective study were to determine the technical success, safety, and midterm results of primary stent placement of infrarenal aortic stenosis. Eight stenoses and one occlusion were treated with stent placement after balloon pre-dilation. Primary technical success was achieved in all patients. Five patients showed reperfusion or restored normal direction of flow of the inferior mesenteric artery. No complications occurred. There was a mean follow-up of 12 months (range, 3-20 months). Primary clinical and hemodynamic patency rates were 100% on follow-up examinations. Stent placement after balloon pre-dilation in properly selected patients with isolated infrarenal aortic stenosis is a promising durable treatment.
