In-Hospital Outcomes in Autogenous Vein Versus Synthetic Graft Interposition for Traumatic Arterial Injury: A Propensity-Matched Cohort From PROOVIT

A retrospective review of the American Association for Surgery Trauma PROspective Observational Vascular Injury Treatment (AAST-PROOVIT) registry from November 2013 to January 2019. Of 460 patients 19 institutions, 402 were treated with autologous vein grafts (AVGs) and 58 prosthetic interposition (PGs) (45 polytetrafluorethylene grafts, 5 Dacron, 8 other). The PG group was more severely injured at admission gunshot wounds a higher mean Severity Score, lactate, transfusion requirements, along significantly lower systolic blood pressure, pH, hemoglobin. After propensity matching, 51 PGs matched 87 AVGs: rates reoperation, endovascular intervention, pseudoaneurysm, infection same, as hospital intensive care unit lengths stay. AAST-PROOVIT data demonstrated that used in critically ill patients. There no in-hospital difference rate repeat intervention or other outcomes between AVGs PGs.
