    Abstract:
    OBJECTIVE: The aim of this study was to describe single-center intraoperative details and early outcome of the new GORE TAG conformable stent graft with ACTIVE CONTROL (C-TAG ACTIVE CONTROL; W. L. Gore & Associates, Flagstaff, Ariz). METHODS: Between September 2017 and June 2018, a consecutive 30 patients underwent thoracic endovascular aortic repair with C-TAG ACTIVE CONTROL. This new system provides an intermediate deployment step at 50% and optional angulation control of the proximal part of the stent graft. Indications for thoracic endovascular aortic repair varied widely, including chronic postdissection and degenerative aneurysms, complicated acute dissections, and intramural hematomas, among others, in an elective (63.3%), urgent (13.3%), or emergent (23.3%) setting. The proximal landing zone (LZ) was LZ 2 in 23.3%, LZ 3 in 43.3%, and LZ 4 in 33.3%. Data were collected retrospectively and analyzed for technical and clinical success. RESULTS: In all patients, the stent graft was successfully introduced and deployed at the intended position, with complete exclusion of aortic disease and without intraoperative mortality (primary technical success, 100%). One emergent patient died at 2 days of ongoing septic shock (clinical success at 30 days, 96.6%). Median follow-up was 107 days (range, 33-271 days); late mortality was 3.4% (one patient died of stent graft infection at 40 days). Freedom from type I and type III endoleak at the early follow-up was 100%. No patients required other surgical or endovascular procedures for the primary treated aortic disease. CONCLUSIONS: Our reported initial experience in 30 patients with the C-TAG ACTIVE CONTROL showed excellent early results, with high deployment accuracy and conformability. The additional features of staged deployment and angulation control may be of great help in challenging aortic arch diseases, allowing precise positioning and preventing bird-beak effect.
