BACKGROUND: Ruptured descending thoracic aortic aneurysm (rDAA) is a rare but devastating condition. Open aortic surgery which uses cardiopulmonary bypass is associated with a high mortality. Thoracic endovascular aortic repair (TEVAR) is a less-invasive approach for which it remains unclear whether outcomes are superior or equivalent to open aortic surgery. In this study, we report our early and midterm outcomes with TEVAR for rDAA.

METHODS: This is an observational, retrospective, single-center study which included patients with rDAA and treated by TEVAR. The main objective was the 30-day in-hospital mortality. Secondary end points were 30-day in-hospital morbidity, 2-year mortality, and technical problems encountered during procedures.

RESULTS: Twenty-five patients were included: 14 men and 11 women with a median age of 76 years (69-82 years). Thirty-day in-hospital mortality rate was 36% (95% confidence interval [CI], 20.6-57.9; n = 9), and the 2-year mortality rate was 44% (95% CI, 27.94-66.72; n = 11). Fifteen patients (60%) presented at least 1 major complication, and 8 of those patients had a second surgery because of it. There were 9 technical problems encountered that required additional open procedures to successfully deploy the aortic stent graft: lack of vascular access in 2 cases (8%), short proximal neck in 3 cases (12%), and short distal neck in 4 cases (16%).

CONCLUSIONS: Mortality and morbidity remain high in patients treated for rDAA by TEVAR. Nonetheless, TEVAR remains an interesting alternative to open aortic surgery especially for older patients with a poor general health and functional status.
