Cranial nerve injuries occur in 2-7% of patients. Recurrent laryngeal and hypoglossal nerve dysfunctions are the most common. Postoperative stroke occurs in 1-5% of patients. [1] The perioperative mortality is 0.5-1.8%. Recurrent stenosis occurs in 1-20% of cases, and reoperation is necessary in 1-3% of cases.

In the CREST data, the rate of restenosis or occlusion at 2 years was approximately 6%, and there was no difference between CAS and CEA. [29] Secondary analysis of the CREST data sought to identify predictors of restenosis or occlusion. Female sex, diabetes and dyslipidemia were independent predictors of restenosis or occlusion at 2 years after either CEA or CAS. Smoking was also found to be an independent predictor; however, this was only noted in patients who had undergone CEA.
