context: BACKGROUND: Endoluminal repair of thoracic aortic pathology has become established in clinical practice, but is associated with significant @entity16 . The aim of this study was to identify factors that were predictive of @entity64 and @entity451 . METHODS: Prospective data was collected for a cohort of 293 consecutive @entity1 having thoracic aortic endovascular repair between August 1997 and September 2009. @entity1 and procedural characteristics were related to the incidence of @entity64 and @entity451 using multivariate logistic regression analysis. RESULTS: The median age was 68 years (18-87), there were 191 @entity1 and 102 @entity1 . Mortality was 5.1% for 195 elective and 13.4% for 98 urgent @entity1 . @entity64 affected 16 (5.5%) @entity1 : 11 affected the anterior and 5 the posterior circulation. Coverage of the left subclavian artery with no revascularisation was the only significant factor predictive of @entity64 (OR 5.34 (1.42-20.40) P = 0.01). @entity451 affected 16 @entity1 (5.5%) but no independent risk factor was identified: 12 were identified perioperatively and 4 were delayed by up to 6 months. CONCLUSION: Covering the left subclavian artery without revascularisation increases the risk of @entity64 following endoluminal repair of thoracic pathology. @entity451 appears to be more complex and no independent precipitating factor was identified.
