Abstract
AimsThe effect of carotid endarterectomy on the patency of the external carotid artery is unknown. We conducted a retrospective study to evaluate the long-term changes in the external carotid artery following carotid endarterectomy.MethodsData was prospectively recorded for all patients who had carotid endarterectomy between 1997 and 2006 in our vascular surgical unit. These patients had follow-up with carotid duplex ultrasound to assess the patency of the internal and external carotid artery. The data were retrieved and evaluated for patency and flow characteristic in both arteries before and after surgery.ResultsCarotid endarterectomy was performed on 255 occasions in 236 patients over the ten year study period. Immediate and long-term outcome of carotid endarterectomy is comparable to results at other major centers. Stenosis of the external carotid artery as detected by duplex scan occurred in 5.5% of patients and was totally asymptomatic.ConclusionOur results of carotid endarterectomy are comparable to other centers. Long-term follow up of the external carotid artery with duplex scan showed asymptomatic stenosis in a small percentage of patients.

During carotid endarterectomy, surgeons often perform avulsion endarterectomy to the external carotid artery
The aim of this study was to evaluate the long term anatomical changes that occur to the external carotid artery following carotid endarterectomy[1]
Summary
Surgeons often perform avulsion endarterectomy to the external carotid artery. Trans-catheter embolization and ligation the external carotid artery is often undertaken to cut the blood supply of large hypervascular tumours, and for bleeding in severe epistaxis and trauma [2]. This procedure is safely performed with no ischaemic consequences to tissues in the head and neck region. Some surgeons routinely performed endarterectomy of the external carotid artery during carotid surgery. Lack of data to support the necessity of that prompted vascular surgeons to do only limited external carotid endarterectomy regardless of its degree of stenosis[1]
