Why carotid endarterectomy is method of choice in treatment of carotid stenosis

Abstract

Procedures used in treatment of carotid stenosis are endarterectomy, PTA with stent implantation, resection with graft interposition and by-pass procedure. Segmental lesions are found more often and treated by the first two mentioned procedures. In case of longer lesions and extension to the greater part of the common carotid artery, the other two procedures are performed. For the past few years, the main dilemma has been whether to perform carotid endarterectomy or PTA with stent implantation. Both early and long-term results speak in favour of carotid endarterectomy, regardless of an increased number of PTA and carotid stenting. At the same time, PTA and carotid stenting are more expensive procedures. Both methods have their defined and important roles in treatment of segmental occlusive carotid lesions. Severe cardiac, pulmonary and renal conditions, which increase the risk of general anaesthesia, are not an absolute indication for PTA and stenting, since endarterectomy can be done in regional anaesthesia. Main indications for PTA with stent implantation are: surgically inaccessible lesions (at or above C2; or subclavian); radiation- induced carotid stenosis; prior ipsilateral radical neck dissection; prior carotid endarterectomy (restenosis).
