Curative observation of carotid artery stenting for treating the patients with symptomatic carotid artery stenosis / 临床神经病学杂志

ABSTRACT

Objective To observe the feasibility and safety of carotid artery stenting(CAS) for treating the patients with symptomatic carotid artery stenosis.Methods 60 patients who were diagnosed with symptomatic carotid artery stenosis by DSA were performed CAS.Among them, 52 cases were onset stenosis of carotid artery,8 cases were extracanical stenosis.The degree of stenosis was 50%～70% in 14 patients,70%～90% in 28 patients and≥90% in 18 patients.64 stents were placed,and 15 filter protection devices were used.Results The drgree of stenosis was decreased from (73.4?9.5)% to (12.5?8.2)%. The plaques were disappear in 53 cases, many debris were found in 5 filter protection divices. The clinical symptoms of all patients were disappear within one week, the mild paralyse was recover in all patients. There were 53 cases with heart rate slowdown during or after operation,the blood pressure declined in 48 cases,and there were 5 patients with vasospasm, as well as one case with cerebral embolization,one case with sydrome of high perfusion and one case with sydrome of low perfusion or swoon. During flowing up for 3 months to 2 years,no one case was found TIA or cerebral infarction,however,only one case was found mild restenosis by DSA.Conclusions CAS is a safety and efficient method for treatment symptomatic carotid artery stenosis. Lowering the risk of operation is done by handling indication seriously and operation skillfully.
