颈内动脉和椎动脉狭窄是缺血性脑血管病的主要病因之一。随着对此病认识的不断加深,PTA与血管内支架成型术治疗颈内动脉和椎动脉狭窄正在逐步兴起,治疗病例数不断增加,治疗效果得到进一步证实。本文就颈内动脉和椎动脉狭窄早期诊断与治疗意义、病变血管的血流动力学改变及治疗时机、血管内治疗的适应证和禁忌证、治疗方法、疗效评价进行了探讨。由于这一技术目前尚未完全成熟,需要不断地积累经验、定期随访、总结疗效。随着新的导管及保护装置的研制应用,其安全性在不断提高,血管内支架成型术是一种安全、有效的治疗方法。
Internal carotid artery and vertebral artery stenosis is one of the main causes of ischemic cerebrovascular disease. With the deepening of awareness of the disease, PTA and endovascular stenting for the treatment of internal carotid artery and vertebral artery stenosis are gradually emerging, the number of cases of treatment continues to increase, the treatment effect has been further confirmed. This article discusses the significance of early diagnosis and treatment of internal carotid artery and vertebral artery stenosis, hemodynamic changes of diseased vessels and the timing of treatment, indications and contraindications of intravascular treatment, treatment methods and efficacy evaluation. As this technology is not yet fully mature, you need to constantly accumulate experience, regular follow-up, summarize the efficacy. With the development and application of new catheters and protection devices, its safety is continuously improving. Endovascular stenting is a safe and effective treatment.
