CompaRison of FEmorofemoral Bypass and Left-Heart ByPass Techniques in Open Thoracoabdominal AortIc Aneurysm Repair

Summary

The study is a multicenter, two-arm, open-label, randomized, parallel-controlled trial, which plans to enroll 236 participants diagnosed with TAAA from 4 hospitals in China. All patients receive TAAAR procedure and are randomized to control group (LHB) and experimental group (fCPB) in the ratio of 1:1. After a 1-year follow-up, the validity and safety of the different cardiopulmonary bypass for TAAAR is evaluated via the incidence of major adverse events including surgical mortality, RRT, stroke, and SCI, as well as intraoperative blood product transfusion volume, mechanical ventilation, and early mortality.
