颈动脉狭窄是卒中的重要原因之一 ,占脑梗死原因的 30 %。颈动脉支架置入术是治疗颈动脉狭窄的一种新方法 ,具有创伤小、安全和并发症少等特点 ,并为禁忌颈动脉内膜切除术的患者创造了新的机会。多组临床试验证实 ,其对卒中二级预防的效果与经典的颈动脉内膜切除术相同 ,并且随着保护技术的应用和防止再狭窄技术的成熟 ,介入治疗将在颈动脉狭窄治疗中发挥更大的作用。 Carotid stenosis is an important cause of stroke, accounting for 30% of the causes of cerebral infarction. Carotid artery stenting is a new method for the treatment of carotid artery stenosis, with less trauma, less safety and complications, and creates new opportunities for contracted carotid endarterectomy patients. Multiple clinical trials have demonstrated that secondary prevention of stroke is as effective as classic carotid endarterectomy and that interventional therapy will play a role in the treatment of carotid stenosis with the application of protection techniques and the prevention of restenosis maturation Greater effect.
