Is debranching thoracic endovascular aortic repair acceptable as the first choice for arch aneurysm in the elderly?†
Abstract
This study aimed to assess differences in midterm outcomes between total arch replacement (TAR) and debranching thoracic endovascular aortic repair (d-TEVAR) and to evaluate the validity of d-TEVAR as the preferred treatment choice for aortic arch aneurysm in the elderly. We reviewed the case histories of 86 patients who had undergone TAR (64 men; mean age 78 ± 2.9 years) and 121 patients who had undergone d-TEVAR (90 men; mean age 82 ± 4.5 years) between 2007 and 2017; of these patients, 50 from each group were matched based on propensity scores to adjust for differences in patient characteristics. Rates of freedom from all-cause mortality at 2 and 4 years were similar between the 2 groups (88% and 77% in the TAR group vs 82% and 64% in the d-TEVAR group, P = 0.11), but rates of freedom from reintervention at 2 and 4 years were significantly higher in the TAR group (100% and 96%) than in the d-TEVAR group (97% and 88%) (P = 0.004). Propensity score matching yielded similar survival rates of 88% and 85% for TAR vs 86% and 71% for d-TEVAR (P = 0.53) and comparable freedom from reintervention rates (100% and 97% in TAR, 98% and 90% in d-TEVAR, P = 0.16) at 2 and 4 years. Cox regression analysis identified previous cerebral infarc...Continue Reading
