Carotid artery pseudoaneurysms are a rare complication of carotid endarterectomy, with few recorded in the literature. We describe a case of a 56-year-old man who presented with symptoms of left hemispheric transient ischemic attack and subsequently underwent a carotid endarterectomy. The patient returned to Accident and Emergency department with an ipsilateral neck swelling found to be an extracranial pseudoaneurysm. Doppler ultrasound imaging was used throughout the management of this patient from preendarterectomy to postpseudoaneurysm bypass. This report discusses the importance of ultrasonography in the diagnosis and follow-up of carotid pseudoaneurysms.
