Influence of Anatomic Distribution of Atherosclerosis on the Outcome of Revascularization with Iliac Stent Placement

Purpose To determine the influence of clinical and angiographic variables, including the anatomic disease pattern, on the outcome of iliac stent placement. Patients and Methods The 455 patients of the study population were divided in three groups according to the anatomic distribution of their peripheral atherosclerosis lesions. Pattern type 1 (focal aortoiliac and/or common iliac lesion) included 180 patients (39.6%), type 2 (external iliac lesion) comprised 58 patients (12.8%), and type 3 (multilevel lesions) included 217 patients (47.7%). Results Complete relief of symptoms immediately after revascularization was observed in 88.3% and 85.4% of patients with pattern type 1 and 2, respectively, compared to 60.1% with type 3 ( P P P P Conclusions Pattern type classification helps identify patients at higher risk for cardiovascular morbidity and mortality. Ideal candidates for iliac stent placement are patients with pattern type 1 or 2 disease.
