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.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
