Summary
Prosthetic patch infection after carotid endarterectomy (CEA) is rare, occurring in 0.85% of cases. Prompt management, including patch removal and reconstruction, is crucial for optimal outcomes and preventing complications like stroke.
Area of Science:
- Vascular Surgery
- Infectious Disease
- Surgical Outcomes
Background:
- Prosthetic patches are used in carotid endarterectomy (CEA) to reduce restenosis.
- Patch infection is a rare but serious complication following CEA.
- Understanding management strategies and outcomes is vital for patient care.
Purpose of the Study:
- To audit the management and outcomes of prosthetic patch infections after CEA.
- To review the existing literature on prosthetic patch infections post-CEA.
- To identify factors influencing patient outcomes.
Main Methods:
- Prospective audit of prosthetic patch infections at Leicester Royal Infirmary.
- Literature review of 43 identified cases of prosthetic patch infections.
- Analysis of causative organisms, management strategies, and patient outcomes.
Main Results:
- Prosthetic patch infection occurred in 0.85% of 936 CEA patients.
- Common organisms included MRSA, Staphylococcus epidermidis, and Staphylococcus aureus.
- Management involved patch removal, antibiotics, and surgical reconstruction (ligation, vein patch, or bypass).
- Autologous venous reconstruction yielded the best outcomes (91% freedom from stroke/death/re-infection at 2 years).
Conclusions:
- Prosthetic patch infection after CEA is infrequent.
- Close surveillance for early wound complications is essential.
- Surgical decisions, such as carotid ligation, benefit from intraoperative monitoring like transcranial Doppler.
