Common femoral artery (CFA) endarterectomy usually requires patch plasty using great saphenous vein (GSV) or occluded superficial femoral artery (SFA) .Alternatively xenografts like bovine pericardium patches may be implanted to reduce operating time as well as to prevent additional incisions and risk of impaired distal wound healing whilst preserving veins for future revascularization. Aim of the prospective study was to investigate the influence of the three different patch materials regarding wound complications and 5-year patency.

All patients with isolated CFA endarterectomy performed in 2016 and 2017 were included. 5-year patency was assessed by ultrasound.

In 129 patients, lymphatic fistulas occurred in 5.4% (7/129), wound infection 4.7% (6/129), wound necrosis or dehiscence 10.9%, negative pressure wound dressing 1.6% (2/12). Significant correlations to wound complications were observed for gender (27.8% men vs. 9.4% women, p=0.03), and operated side (31.8% right vs. 14.3% left, p=0.02). The average operating times were 113.7 minutes for bovine pericardium, 120.4 minutes for venous and 116.7 minutes for SFA patches showing no statistical differences. Surgeries shorter than 120 minutes showed a significant lower complication rate (13.1%) than surgeries longer than 120 minutes (42.4%). At 5 year follow-up, ultrasound examination in 18 patients did not show any significant restenosis.

No significant difference in wound complications or restenosis were observed. Further studies with a larger patient number are warranted to clarify the effect of patch materials in the groin on wound healing and patency.
