Abstract

Purpose To investigate the midterm outcomes of thoracic endovascular aneurysm repair (TEVAR) with the use of the Seal stent graft for four categories of thoracic aortic disease. Materials and Methods This retrospective multicenter study evaluated the records of 216 Korean patients who underwent TEVAR with the Seal stent graft during 2007–2010. The study outcomes were (i) perioperative death, (ii) endoleak, (iii) repeat intervention, (iv) aortic-related death, and (v) all sudden unexplained late deaths. Results The overall technical success rate was 94% (203 cases), and the disease-specific rates were 97% (88 cases) for aneurysms, 96% (71 cases) for dissections, 82% (32 cases) for traumatic aortic disease, and 100% (12 cases) for intramural hematoma and/or penetrating aortic ulcer. There were 6 acute surgical conversions (2 for aneurysms and 4 for dissections). There were 18 endoleaks, 4 retrograde ascending aortic dissections, and 6 stent graft–induced new entries. The 1-, 3-, and 5-year overall survival rates were 93% ± 3, 90% ± 4, and 90% ± 4, respectively. Conclusions TEVAR with the Seal thoracic stent graft provided a high technical success rate and low mortality and complication rates during midterm follow-up. However, additional long-term studies are needed to evaluate the durability and late complications associated with this device.
