Abstract

BACKGROUND:

Thoracic endovascular aortic repair (TEVAR) is used in patients with thoracic aortic aneurysms (TAA) and uncomplicated type B acute aortic dissection (B-AAD) to reduce morbidity and mortality. Limited data are available for comparing outcomes of TEVAR in TAA vs B-AAD.

METHODS: 49 patients with TAA and 37 patients with B-AAD between January 2005 and January 2015 were retrospectively identified. Baseline characteristics, thrombosis status of the false lumen with the extent of dissection, aortic pathologies including prior aortic surgeries, emergent vs elective procedures, landing zone location, extra anatomical major vessel bypass, types of grafts and outcome variables were reviewed by two physicians. T-test, Wilcoxon rank-sum test and chi-square test were used to generate pvalues.

RESULTS: The sample population with TAA had a higher median age than those with B-AAD (72 years vs 59 years, p¼0.0001) (Table). Early events, 30-day mortality and 5-year outcomes were not significantly different between groups. Endoleak and all-cause mortality with TEVAR were not significantly different in the groups (Fig).

CONCLUSION: This study confirms the feasibility of TEVAR for uncomplicated type B aortic dissection in the acute setting with no difference in short- or long-term outcomes of TEVAR between TAA and B-AAD populations.
