Management and Outcome of Prosthetic Patch Infection after Carotid Endarterectomy: A Single-centre Series and Systematic Review of the Literature

AbstractObjectivesOutcomes following prosthetic patch infection after carotid endarterectomy (CEA).MethodsRetrospective audit and systematic review.Results22 patients were treated between January 1992 and April 2012, 5 having undergone their original CEA at another institution. The commonest infecting organism was Staphylococcus. One patient was treated by antibiotic irrigation, one was stented, while 20 underwent debridement and patch excision plus; carotid ligation (n = 3), vein patching (n = 3) or vein bypass (n = 14). There was one peri-operative stroke, but no peri-operative deaths. There were no reinfections at a median follow-up of 54 months.A systematic review identified 123 patients with prosthetic patch infection in the world literature. Thirty-six (29%) presented <2 months, 78 (63%) presented >6 months after the original CEA. Seventy-nine of/87 patients (91%) with a positive culture yielded Staphylococci or Streptococci. Seventy-four patients were treated by patch excision and autologous reconstruction. Four (5%) developed reinfection
