颈动脉狭窄是导致脑梗死的重要原因之一。颈动脉血管成形和支架置入术(CAS)已被证实能够预防卒中发生,临床应用越来越广。尽管CAS是一种微创治疗方法,但仍然有许多潜在的并发症,如血流动力学异常、过度灌注综合征、脑梗死和再狭窄等。文章对CAS的并发症及其处理方法进行了综述。 Carotid stenosis is one of the important causes of cerebral infarction. Carotid angioplasty and stenting (CAS) have been shown to prevent stroke and have become more widely used clinically. Although CAS is a minimally invasive treatment, there are many potential complications such as hemodynamic abnormalities, over-perfusion syndrome, cerebral infarction and restenosis. The article reviewed the complications of CAS and its treatment methods.
