Prospective evaluation of automated vascular analysis for ilio-femoral artery lesions before and after percutaneous endovascular aortic repair.

ABSTRACT

BACKGROUND: This study was conducted to evaluate the differences between pre- and postoperative access conditions in percutaneous endovascular aortic repair (PEVAR). METHODS: Between December 2021 and October 2023, PEVAR was performed on 61 patients using the Perclose ProStyle (Abbott Vascular). Enhanced computed tomography and ankle-brachial index tests were performed preoperatively and postoperatively. The inner diameter and area of the iliofemoral artery were automatically measured, and the pre- and postoperative values were compared (114 legs). The same analysis was performed on 12 legs with previous groin operations; open surgical EVAR was performed in 9 legs, an endarterectomy of the femoral artery in 1, and a femoropopliteal bypass in the other leg. RESULTS: All patients were discharged without surgical site infections, lymphatic fistulas, or retroperitoneal haematomas. There were no significant differences between the pre-and postoperative inner diameter and inner area of the external iliac artery and common femoral artery. There were no significant differences between the preoperative and postoperative ankle-brachial index tests. In 12 legs with a previous groin operation, the postoperative ankle-brachial index tests and inner diameter and area of the external iliac artery and common femoral artery were statistically equal to the preoperative values. CONCLUSIONS: This study can support the safety of percutaneous endovascular aortic repair, even in patients with redo groin operations.
