Midterm outcomes of the covered endovascular reconstruction of the aortic bifurcation for aortoiliac occlusive disease in a latinoamerican population.

Surgical approach of aortoiliac occlusive disease (AOD) with aorto-bi-femoral graft or endarterectomy, has been the first line treatment with patency rates up to 90%. Nevertheless, this procedure has an early mortality rate of 4%. Vascular complications of aorto-bi-femoral graft have an average incidence of 5–10% and development of incisional hernia in 10% of the cases. The Covered Endovascular Reconstruction of Aortic Bifurcation or CERAB technique, as a new approach is shaping up to be a promising approach. However, there are few studies in Latin America and the Caribbean. Retrospective multicenter study. All patients treated with the CERAB technique between February 2015 and June 2021 in three hospitals. A total of 9 patients (5 male and 4 female) were treated with the CERAB technique. Only one patient died. Of the total number of patients, 41.2% had a TASC II - C classification, and 58.8% had a TASC II - D classification. Complications included dissection in only 2 patients, massive bleeding in 1 patient and hematoma in 3 patients. The average number of days in critical care was 1.2 days and 2.6 in hospitalization. Two patients required endovascular reintervention. Primary patency was present in 66.7% of the patients. The CERAB technique presents a low morbidity and mortality with an 88.9% of technical success rate. None of our patients needed Chimney CERAB procedure. Our results are similar to those reported in the literature, where they report primary patency rates between 82% and 97%. • CERAB technique for TASC II C and D patients is safe and feasible. • CERAB technique is an alternative for open surgery in Latin America. • CERAB technique has primary patency rates between 82% and 97%.
