Case Report: Management challenges of late presentation Dacron patch infection after carotid endarterectomy

摘要

An 83-year-old man presented 4 years after right carotid endarterectomy (CEA) with an infection of his prosthetic Dacron patch. Initial scans (CT angiogram and whole body labelled white cell scan) were clear with no infection or collection noted. Systemically, the patient presented well with no recorded fevers. With an occluded left internal carotid artery and severely stenosed vertebral arteries, surgery presented a high risk of major stroke due to the lack collateral supply and this was discussed extensively. The patient subsequently declined surgical management, and he was monitored closely on an outpatient basis. He presented again a year later with ongoing haemoserous ooze from the CEA site. Subsequently a two-stage procedure was performed, where initially a stent was inserted, followed by patch excision and debridement. A muscle flap was then mobilised over the opening. This new approach to carotid patch infections should gain traction over time as a safer alternative for high-risk patients.
