Influence of anatomic distribution of XXXX on the outcome of revascularization with iliac stent placement.

@entity1 @entity731 @entity75 @entity65
PURPOSE: To determine the influence of clinical and angiographic variables, including the anatomic disease pattern, on the outcome of iliac stent placement. @entity1 AND METHODS: The 455 @entity1 of the study population were divided in three groups according to the anatomic distribution of their peripheral @entity731 lesions. Pattern type 1 (focal aortoiliac and/or common iliac lesion) included 180 @entity1 (39.6%), type 2 ( @entity75 ) comprised 58 @entity1 (12.8%), and type 3 (multilevel lesions) included 217 @entity1 (47.7%). RESULTS: Complete relief of symptoms immediately after revascularization was observed in 88.3% and 85.4% of @entity1 with pattern type 1 and 2, respectively, compared to 60.1% with type 3 (P < .05). The persistence of clinical benefit at 36-month follow-up was 91.6%, 97.9%, and 60.8% in disease patterns 1, 2, and 3, respectively. The overall 1-year mortality rate was 3% with type 1 lesions, 5.7% with type 2, and 9.7% with type 3. On multivariate logistic regression, the presence of a disease pattern type 3 was the most powerful indicator (P < .001) of early unsatisfactory clinical outcome in iliac stent placement. Unexpectedly, female gender was predictive of unsatisfactory clinical outcome (P < .01) and higher periprocedural complications (P < .001) following iliac stent revascularization. CONCLUSIONS: Pattern type classification helps identify @entity1 at higher risk for @entity65 and mortality. Ideal candidates for iliac stent placement are @entity1 with pattern type 1 or 2 disease.
