This study states that Vascular surgical groin wound infection (VS-GWI) has multiple causes and frequently is manifested as a limb- or life-threatening problem, resulting in significant morbidity and mortality. For patients undergoing operative extirpation, in situ repair, extra-anatomic bypass, or ligation can be used; however, limited data exist describing comparative results of the different operative choices or conduit subtypes. Therefore, we sought to describe our experience with management of VS-GWI and to detail outcomes of the different strategies.

Patients (2003-2017) undergoing surgical treatment of VS-GWI (Szilagyi grade III) secondary to primary infectious arteritis or infected pseudoaneurysm after percutaneous intervention as well as previous prosthetic graft placement were reviewed. The primary end point was major adverse limb events (MALEs; major amputation, graft occlusion, or unplanned reintervention). Secondary end points included 30-day mortality, wound healing, amputation-free survival (AFS), and all-cause mortality. Cox proportional hazards modeling was used to determine relative risk of end points; Kaplan-Meier methodology was employed to estimate freedom from outcomes.
