Intraoperative Evaluation for Endoleaks Using the SCORPION Procedure During Endovascular Aortic Repair
VASCULAR(2024)
摘要
Objectives Endoleaks are important complications of endovascular aortic repair. Usually, endoleaks are judged indirectly by aortography or postoperative computed tomography. However, findings from these modalities are difficult to distinguish because of the divergency of endoleaks. Few studies have reported direct visualization of endoleaks. Herein, we introduce a direct procedure for intraoperatively evaluating endoleaks using angioscopy.Methods From April 2023, consecutive patients with an abdominal aortic aneurysm, except emergency cases and those of narrow access, seen at Sunagawa City Medical Center were enrolled in our study. Endoleaks were detected by intraoperative angioscopy using a novel endovascular procedure.Results Seven patients underwent endovascular aortic repair of an abdominal aortic aneurysm with intraoperative angioscopy. None of the enrolled patients experienced complications. The procedure revealed types 2, 3a, and 4 endoleaks.Conclusions This is the first study to demonstrate intraoperative visualization of endoleaks using angioscopy. Direct findings observed by this novel procedure might provide information on the velocity and volume of the endoleak, providing comprehensive insights into the intra-sac hemodynamics after the endovascular aortic repair.
