目的探讨髂动脉粥样硬化狭窄的支架植入治疗的安全性和疗效。方法髂动脉粥样硬化狭窄患者15例,病变长度4.3~9.5 cm,平均6.7 cm,间歇性跛行间距100~300 m。应用大剂量局部溶栓+支架成形术(PTAS)治疗。术后追踪采用动脉彩超或16层CT以及踝肱指数(AB I)。结果本组支架植入治疗的技术成功率为100%,术后患者的症状和体征明显改善,AB I由术前的0.25±0.18增至术后14 d的0.85±0.15(P=0.00)。随访3~47个月,其中1例男性高龄患者于治疗3个月后,因脑干血栓死亡,其余患者均健在,无1例出现再狭窄及闭塞。11例患者跛行症状消失,3例患者跛行间距>1000 m。结论髂动脉粥样硬化狭窄的支架植入治疗的近、远期疗效满意,安全可靠。
Objective To investigate the safety and efficacy of stent implantation in patients with iliac artery atherosclerosis. Methods Fifteen patients with iliac artery atherosclerosis were stenosed with a length of 4.3 ~ 9.5 cm (average 6.7 cm). The interval between intermittent claudication was 100 ~ 300 m. Application of high-dose local thrombolysis + stent (PTAS) treatment. Postoperative follow-up using arterial ultrasound or 16-slice CT and ankle brachial index (ABI). Results The technical success rate of stent implantation in this group was 100%. The postoperative symptoms and signs of patients were significantly improved. The ABI increased from 0.25 ± 0.18 before surgery to 0.85 ± 0.15 (P = 0.00) after 14 days. All the patients were followed up for 3 ~ 47 months. One of them, aged male, died of cerebral thrombosis after 3 months of treatment. The rest of the patients were alive without any restenosis and occlusion. The symptoms of claudication in 11 patients disappeared, and the lameness spacing was> 1000 m in 3 patients. Conclusion The treatment of iliac artery atherosclerosis with stent implantation has satisfactory short-term and long-term results and is safe and reliable.
