Clinical Outcomes of Distal Tapered Restrictive Covered Stent Applied in Endovascular Treatment of Aortic Dissection Involving Zone 0

The safety and efficacy of a distal tapered restrictive covered stent (RCS) applied in the endovascular treatment of aortic dissection involving Zone 0 was evaluated. This study retrospectively analysed 43 patients with acute aortic dissection involving Zone 0 who received in situ laser fenestrated thoracic endovascular aortic repair with distal tapered RCS from January 2015 to February 2019. The indication for the distal tapered RCS procedure was an inappropriate distal size of the main stent graft. Technical success, aortic remodelling, and clinical outcomes were evaluated. Technical success was achieved in all patients. The 30 day post-operative mortality rate was 0%. All patients had complete false lumen thrombosis in the stent coverage segment. True lumen volume increased significantly (p
