Abstract
Objective: To evaluate the safety and efficacy of carotid endarterectomy (CEA) and carotid angioplasty with stenting(CAS) for carotid artery stenosis after radiotherapy. Methods: The clinical data of 73 cases with carotid artery stenosis after radiotherapy from October 2007 to September 2017 were analyzed retrospectively. Among them, 36 cases underwent CEA and 37 cases underwent CAS. Results: No complications occurred during the perioperative period in both groups. During the follow-up period, transient cerebral ischemia occurred in 1 case in the CEA group. There was no in-stent restenosis or adverse events such as stroke or myocardial infarction. In the CAS group, transient cerebral ischemia occurred in 2 cases, postoperative restenosis occurred in 2 cases, and myocardial infarction occurred in 1 case. The restenosis rate and incidence of adverse events were lower in the CEA group. Conclusions: Both surgical methods are safe and effective in the treatment of carotid artery stenosis after radiotherapy. CEA surgery can be more beneficial to long-term outcome, and it is supposed to be the preferred surgical method.
