目的 评价盐酸沙格雷酯治疗慢性下肢动脉闭塞症的有效性和安全性。方法 对根据临床症状、下肢三维血管重建（CTA）或血管造影检查诊断为慢性下肢动脉硬化闭塞症的32例患者，采用盐酸沙格雷酯（100 mg/片）治疗，1片/次，3次/d，餐后口服，连续4周。用药24个月后观察患者临床症状的改善情况，分析盐酸沙格雷酯的治疗效果。结果 用药24个月期间，失访3例，获访29例。综合疗效显效6例，良好15例，改善5例，无效3例，总有效率为89.7% （26/29）。治疗前后患者的凝血系统和临床生化各指标比较差异均无统计学意义（P＞0.05）。用药后3例（10.3%）患者出现轻度恶心和胃部不适，2例（6.9%）患者出现轻度皮疹，其余患者均无不良反应出现。安全性评价安全没问题24例，稍有问题5例。结论 盐酸沙格雷酯可以改善慢性下肢动脉硬化闭塞症患者的临床症状。
ObjectiveTo compare the clinical efficacy of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in the treatment of patients with carotid artery stenosis, and to provide a more abundant evidence-based medicine for the treatment of CEA and CAS in patients with carotid artery stenosis. MethodsForty patients with carotid artery stenosis were randomly divided into CEA group and CAS group based on the operative indication. Patients in CEA group were given carotid endarterectomy treatment and those in CAS group were given carotid artery stenting treatment. Then clinical efficacy of the two groups were observed and compared. ResultsIn terms of the occurring rate of perioperative complications, cardiovascular events in 3 months after operation, and some major end events such as stroke, death and so on, the comparative difference between the two groups was of no statistical significance (P > 0.05). Through the followed-up visits of 12 months, the comparative difference between the two groups was also of no statistical significance (P > 0.05) in terms of the occurring rate of carotid artery restenosis and disabling or fatal stroke. ConclusionsFor patients with severe extracranial carotid stenosis under indication of operation treatment, carotid endarterectomy and carotid artery stenting are of equivalent clinical efficacy, and both of them are of high security, although further study with large-amount and evidence-based medical data in long term from multiple centers is still in need.
