CERCAS Trial

The purpose of the study is to compare the safety and effectiveness of carotid endarterectomy with stent removal (CEASR) and repeat percutaneous transluminal angioplasty with or without stenting (rePTA/S) in patients with carotid in-stent restenosis. Consecutive patients with carotid in-stent restenosis (≥80%) were randomly allocated to the CEASR or rePTA/S group. The incidence of residual stenosis after intervention, stroke, transient ischemic attack myocardial infarction and death 30 days and 1 year after intervention and restenosis 1 year after intervention between patients in CEASR and rePTA/S groups were statistically evaluated. All demographic data of enrolled patients and study results data are in the dataset.
