Patch Infection Following Carotid Endarterectomy: A Single-Center Audit and Literature Review.

Introduction: Carotid endarterectomy (CEA) is a surgical procedure that carries a rare but serious risk of patch infection. This study examines the management and outcomes of patch infections in CEA patients treated in our department over 23 years. A literature review of studies on prosthetic patch infection following CEA published from January 1992 up to December 31, 2022 was also carried out.

Methods: We conducted a retrospective audit of patients who underwent CEA in a hospital in Athens, Greece, between January 1, 1999, and December 31, 2022.

Results: Between January 1999 and December 2022, we treated seven patients with carotid patch infections who had their original CEA at our department. and were the most common infecting organisms. One patient (14%) died from hemorrhagic shock before surgery, while the remaining six (86%) underwent debridement, patch excision, and great saphenous vein patching. No peri-operative deaths or strokes occurred, and there were no re-infections during a median follow-up of 159 months.

Conclusions: Excision of infected material followed by revascularization using a vein graft remains the prevailing treatment.
