Thoracic endovascular aortic repair with laser in situ fenestration of aortic dissection involving the arch:a single-center clinical outcomes and criteria of stent selection
Objective To report the clinical outcomes of thoracic endovascular aortic repair with laser in situ fenestra-tion of aortic dissection involving the arch in a single center,and to summarize the clinical experience of stent selection criteria.Methods The clinical data of 330 patients with aortic coarctation involving arch branches treated with thoracic endovascular aortic repair with laser in situ fenestration in our hospital from January 2016 to April 2023 were retrospec-tively analyzed,including the general information of patients,surgical procedures,technical success rate,and surgical complications.The clinical outcomes were summarized and the selection criteria for aortic stents and branch artery recon-struction stents were analyzed.Results All patients underwent thoracic endovascular aortic repair with laser in situ fen-estration,with a mean operation time of(176±51)minutes and a fenestration technique success rate of 98.1%.There were 10 in-hospital deaths(3.03%),8 symptomatic strokes(2.68%),41 endoleaks(12.4%),2 proximal stent-in-duced new entries(0.61%),and no distal stent-induced new entries were observed.Follow-up CT angiography[(24±7.9)months]demonstrated a branch vessel patency rate of 96.58%.Conclusion Laser in situ fenestration with thoracic endovascular repair of aortic dissection involving the arch is a safe and effective technique with a high success rate and a low complication rate.
