Evaluation of the Castor Single Branch Stent Graft in Treatment of Acute Aortic Syndrome

Real-world Experience With the Castor Single Branch Stent Graft in the Management of Acute Aortic Syndrome

The objective of this study to evaluate the safety and effectiveness of the Castor single branch stent graft for endovascular repair of acute aortic syndrome patients without an inadequate proximal landing zone (<15mm)

The goal of this observational, ambispective, and multicenter cohort study is to evaluate efficacy and safety of the Castor single branch stent graft.

205 patients who received thoracic endovascular aortic repair by meant of the Castor single branch stent graft from June 2018 to June 2022 were enrolled in our study. All enrolled patients have an inadequate proximal landing zone (<15mm) , and they underwent routine follow-up after thoracic endovascular aortic repair at 1-month, 6-months, and 1-year for the following, but not limited to assessment: physical examination, laboratory test and the CT angiography.

Meanwhile, the enrolled patients will come for continuous follow-up at 2-years, 3-years, and annually to 10-years post-procedure.

Inclusion Criteria:

• Patients with acute Stanford type B aortic syndrome who received thoracic endovascular aortic repair by meant of Castor single branch stent graft from June 2018 to June 2022

Exclusion Criteria:

• Patients with acute type B aortic syndrome with an adequate proximal landing zone (≥15mm)
• Previous endovascular repair of the aorta
• Patients with missing data and loss of follow-up
