ABSTRACT
OBJECTIVES: Infected carotid prosthetic patches (ICPP) are a rare but catastrophic complication of carotid endarterectomy (CEA). Prevention and appropriate surgical management is essential. We report our experience of carotid artery reconstruction for ICPP. DESIGN: Single-center retrospective study. METHODS: 10-year review of the surgical treatment of ICPP. RESULTS: Twelve patients presented with patch infection following CEA. Three patients presented acutely with an expanding hematoma, eight with chronic complications (abscess/discharging sinus n = 5, carotid pseudoaneurysm n = 3). Mean age was 75 years. Replacement conduits included superficial femoral artery (n = 6), cadaveric homograft (n = 3), long saphenous vein (n = 2) and one patient had primary closure. Five patients had muscle flaps fashioned for carotid artery protection. Operative complications included hypoglossal nerve injury (1 patient), superficial skin infection (2 patients) and one patient was returned to the operating room for a neck haematoma. Five surgical specimens were culture positive for: Staphylococcus aureus (n = 3), Corynebacterium propionibacterium (n = 1) and Streptococcus anginous (n = 1). There were no 30-day mortalities. Mean hospital stay was 6 days. Median follow-up was 16 months (range 3-108 months). CONCLUSION: Carotid artery reconstruction in a contaminated wound represents a significant surgical challenge. Unlike previous reports that used venous conduits, this is the first series where cadaveric or autologous arterial conduits were preferred. Arterial conduits achieved durable short term follow-up.

BACKGROUND: Shortened trainingtimes duetothe European Working Time Directive (EWTD) and increased public scrutiny of surgical competency have led to a move away from the traditional apprenticeship model of training. Virtual reality (VR) simulation is a fascinating innovation allowing surgeons to develop without the need to practice on real patients and it may be a solution to achieve competency within a shortened training period. METHOD: A Medline search was performed to identify studies and commentaries on the use of VR simulators in endovascular training. FINDINGS: Three studies on carotid stenting and four on peripheral vascular angioplasty demonstrate that simulator training is a valid, feasible and acceptable training tool. One randomised study reports that these skills learned on simulators are transferable to the operating room. CONCLUSION: VR simulators have a role in competency based, structured training of vascular interventionalists and should improve patient safety.

We present a case of blunt trauma to the buttock resulting in an inferior gluteal artery pseudoaneurysm and arteriovenous fistula. The characteristic diagnostic features on CT angiography and digital subtraction angiography (DSA), along with the emergency percutaneous management of this traumatic vascular injury, are described. A review of the literature demonstrates inferior gluteal artery pseudoaneurysm is a rare condition, while successful treatment with glue embolization is previously unreported.
