A Preliminary Experience on Prefabricated Bovine Pericardium Grafts for Aorto-iliac and Infrainguinal Reconstructions

Surgical treatment of aortic and peripheral graft infections their prevention in case systemic infection requires the employment autologous material. If not available, other biological substitutes have been proposed. Among those, prefabricated bovine pericardium grafts (pBPGs) recently become commercially available for aorto-iliac reconstructions. Available literature on these prostheses is scarce. We evaluated short-term outcomes pBPGs infra-inguinal reconstructions management infections. A multicenter retrospective analysis all patients submitted to (Group 1) artery 2) revascularization with BPGs from August 2019 October 2022 was performed. Primary patency, freedom reinfection, mortality, complication rates, reinterventions were analyzed. Follow-up performed by clinical ultrasonographic evaluation at discharge, 6 months, yearly thereafter. Thirty-six included study, 23 (64%) group 1 (G1) 13 (36%) 2 (G2). The median age 73 years (interquartile range, 67.5-76.5 years). Patients predominantly males (83%). Indication surgery a previous vascular 17 cases (74%) G1 five (38%) G2 presence (22%) eight (62%) G2. One patient (4.4%) had an aortoenteric fistula. Technical success 100% both groups. Median follow-up months groups (range, 1-24 months). Thirty-day mortality 17.4% 8% Overall 25% no aortic- or graft-related deaths. primary cause death septic shock 33%. An iliac limb occlusion occurred three (19%) G1, requiring reintervention. common anastomotic pseudoaneurysm successfully managed endovascular exclusion.
