Midterm Results of the Treatment of Penetrating Abdominal Aortic or Iliac Artery Ulcer with the BeGraft Balloon-Expandable Covered Stent—A Single-Center Experience

Abstract

The purpose of the study was to evaluate the feasibility and efficacy of the novel BeGraft covered stent for the treatment of abdominal penetrating aortic ulcer (PAU) or penetrating ulcers of the iliac arteries (PUIAs). This was a single-center observational study, which included 24 consecutive patients who underwent endovascular surgery due to abdominal PAU or PUIA between June 2017 and September 2019. Demographics of patients, lesion characteristics, diameter and length of the BeGraft stents, and postoperative events were prospectively collected and retrospectively analyzed. Follow-up examinations were performed at 1, 6, 12, and 24months with clinical and hemodynamic evaluation. Outcome measures included technical success, perioperative complications, and stent patency. A total of 24 patients (13 men and 11 women), with a median age of 67years (range, 42-81years), were analyzed. Among them, 20 patients were symptomatic, and 4 patients underwent elective surgery because of the size of PAU. A total of 54 BeGraft stents (26 aortic and 28 peripheral) were successfully delivered and deployed to cover 13 aortic and 13 common iliac artery ulcer lesions. The technical success rate was 100%. The average procedural time was 53.8±12.8min. Complications included one case of the access-site pseudoaneurysm, which was successfully treated by thrombin injection. During a median follow-up of 20.5months (range, 6-33months), all stents remained patent, without endoleak or ulcer recurrence. BeGraft stents used during endovascular treatment of abdominal PAU and PUIA lesions are associated with favorable outcomes regarding technical success and patency. The primary use of BeGraft covered stents provides a valid option for patients with abdominal PAU. Long-term follow-up is required to confirm these promising results.
