Endovascular treatment outcomes of chronic thoracoabdominal aortic dissection
Objective To evaluate the feasibility,safety and efficacy of endovascular treatment for chronic thoracoabdominal aortic dissection.Methods The patients with chronic thoracoabdominal aortic dissection who underwent total endovascular treatment at Shanghai City First People's Hospital between December 2021 and March 2024 were retrospectively analyzed.The patients were divided into single-trunk group and double-trunk group according to the treatment methods.Clinical data including demographic characteristics,preoperative risk factors,surgical details,postoperative complications and long-term follow-up data were collected.Outcome measures mainly included surgical success rate,in-hospital mortality,endoleak rate and incidence of branch restenosis.Results Thirty-four patients with thoracoabdominal aortic dissection were treat with total endovascular treatment.That success rate of operation was 100％.The in-hospital mortality was 2.94％.the incidence of paraplegia was 0.00％.the incidence of cerebral infarction was 2.94％.The incidence of type Ⅲ endoleak was 5.88％.The incidence of branch artery stenosis was 8.82％.The incidence of dissection progression was 8.82％.The reintervention rate was 14.71％.In the aspect of reconstruction of splanchnic artery branches,fenestration stent was the main method in the single-trunk group,and branch stent was the main method in the double-trunk group,the difference was statistically significant(P＜0.05).There was no significant difference in perioperative and mid-term follow-up results between the two groups(P＞0.05).Conclusion Total endovascular treatment is a safe and effective treatment option for patients with thoracoabdominal aortic dissection.
