Abstract

Objective: To evaluate the mid-term outcomes of the covered endovascular reconstruction of the aortic bifurcation (CERAB) technique in patients with bilateral aortoiliac occlusive disease treated at Cho Ray Hospital. Methods: This retrospective descriptive study included 20 patients diagnosed with bilateral aorto-iliac artery stenosis who were treated with the CERAB technique at the Department of Vascular Surgery, Cho Ray Hospital from May 2022 to January 2024. Evaluation criteria included the success rate of the technique, perioperative complications, vascular patency rate, and clinical improvement during the medium-term follow-up period.Results: The mean age of the study group was 67.5 ± 9.2; males accounted for 75%. The technical success rate was 95% of the study sample. The ABI index improved from 0.44 ± 0.11 before intervention to 0.65 ± 0.12 after intervention (p<0.001). There was one case of perioperative thrombotic embolism immediately after intervention, which was promptly managed. The mean follow-up time was 19.4 ± 6.2 months. The rate of primary circulation at 24 months was 80%; the rate of secondary circulation was 89%.Conclusion: The CERAB technique is a safe, minimally invasive, and effective treatment option for bilateral aortoiliac occlusive disease. Mid-term results demonstrated high technical success, significant hemodynamic and clinical improvement, and favorable patency outcomes.
