OBJECTIVE: Bovine pericardial patches (BPP) are frequently used for arterial reconstruction, but little data exist regarding their ability to resist infection. We hypothesize that BPP would provide a reasonable alternative to autologous vein patches in infected fields. METHODS: We used BPP to repair 51 arteriotomies (25 brachial, 23 femoral, three popliteal) in 48 consecutive patients (mean age, 68 years; 65% men, 75% diabetic, 67% dialysis dependent) undergoing removal of infected (33 gram-positive, three gram-negative, eight mixed flora, and four culture-negative) polytetrafluoroethylene grafts (35 arteriovenous grafts, nine femoral-distal bypasses, and four femoral patch angioplasties) between January 2007 and January 2011. Patient records were retrospectively reviewed and outcomes, including death, rupture, secondary reconstruction, and infection, were recorded. RESULTS: Over a mean follow-up of 2.1 years (range, 3-48 months), 50 of 51 patches remained in place without evidence of recurrent infection, rupture, or revision. One patient had acute rupture of a popliteal arteriotomy 1 week postrepair and had subsequent ligation and above-knee amputation. Eight of the 48 patients died from unrelated causes during follow-up (three withdrew from dialysis, three myocardial infarction, and two unknown). CONCLUSIONS: BPP provide a durable alternative to saphenous vein for arterial reconstruction following removal of infected arterial grafts.
