The role of carotid endarterectomy in the endovascular era.
OBJECTIVE
Carotid artery angioplasty and stenting (CAS) has been proposed as an alternative to surgery for patients with high-grade symptomatic carotid disease. The purpose of this study was to determine the proportion of patients that were suitable for each type of intervention and to analyse the reasons that precluded stenting.


METHODS
This was a prospective observational study. All patients considered for intervention for carotid artery disease during an 18-month period were analysed. The management decision was recorded, as were the reasons for unsuitability for stenting.


RESULTS
Two hundred and sixty-eight patients' data were analysed, 224 had complete records. Forty-seven patients did not require intervention and received best medical treatment alone. One hundred and seventy-seven patients required intervention, 113 were suitable for stenting and 64 were not. In 51 patients stenting was preferred. Sixty-two patients were suitable for either stent or surgery. Sixty-four patients were unsuitable for stenting. Carotid tortuosity and proximal disease accounted for 70% of this group.


CONCLUSIONS
Current enthusiasm for carotid stenting might well be supported by the results of ongoing randomised-controlled clinical trials. However, this study highlights a significant proportion (64/177; 36%) of our patients is presently unsuitable for stenting. The common technical difficulties and limitations of stenting encountered in our unit are related predominantly to carotid anatomy.
