Abstract

Objective: The purpose of the study is to evaluate the short-term outcomes of the on table fenestration method in endovascular aortic intervention. Subjects and methods: This is a retrospective study conducted from January 2020 to July 2023 and a prospective study from July 2023 to September 2024. A total of 51 patients with acute aortic syndrome were treated with endovascular stent graft placement with on table fenestration. Patients were diagnosed, underwent computed tomography (CT) of the aorta, and received endovascular aortic intervention using the on table fenestration method to maintain subclavian artery perfusion. The success rate of the procedure, procedural complications, and survival rates over time were evaluated. Results: The planned procedure success rate was 92.2%. Some procedural complications included acute renal failure (9.8%), death (3.9%), acute blood loss (3.9%), and stroke (2%). The clinical success rate was 88.2%. The survival rate was 95.9% after 1 month, 93.9% after 3 months, 85% after 24 months, and 78.4% after 26 months, remaining stable after 26 months. The incidence of cardiovascular events was 4.1% after 1 month, 12.8% after 6 months, 15.2% after 24 months, and 28.3% after 27 months, stabilizing after 27 months. Conclusion: Endovascular aortic stent graft placement with on table fenestration to maintain subclavian artery perfusion is a minimally invasive procedure with a high success rate and a relatively low complication rate.
