脑卒中是当今第三大致死病因,是成年人致残的首要原因。颈动脉狭窄是导致缺血性卒中事件发生的最常见原因。20世纪80～90年代已有多个随机对照试验证实颈动脉内膜剥脱术相比于内科药物治疗对于预防卒中具有明显优势。近年来,随着介入技术和器材的不断进步,血管腔内介入治疗愈发成熟,其安全性及有效性正在为一些大规模的临床随机对照试验所证实,腔内介入治疗颈动脉狭窄正在挑战着外科内膜剥脱术的“金标准”地位。 Stroke is the third leading cause of death in the world and is the leading cause of disability in adults. Carotid stenosis is the most common cause of ischemic stroke. Several randomized controlled trials in the 1980s and 1990s have demonstrated that carotid endarterectomy has significant advantages in stroke prevention compared to medical treatment. In recent years, with the continuous improvement of interventional techniques and equipment, the endovascular interventional therapy becomes more and more mature. Its safety and efficacy are confirmed by some large-scale randomized controlled clinical trials. Endovascular interventional treatment of carotid artery stenosis is challenging With surgical endometrial stripping “gold standard ” status.
