OBJECTIVE
The natural course of chronic carotid artery total occlusion (CTO) is poor. Previous reports suggested that carotid artery stenting (CAS) improves the clinical outcome of CTO. However, its long-term efficacy has not been established. This study assessed the mid- and long-term clinical outcome of CAS for CTO.
METHODS
We evaluated the clinical outcome of 15 patients who underwent CAS for CTO between September 2010 and October 2019.
RESULTS
The technical success rate of recanalization was 93.3% (14 of 15 patients). Eight patients were treated using self-expanding stents, and six were treated using self-expanding coronary stents. Symptomatic procedure-related complications developed in two patients (13.3%). During the follow-up period (mean 34.9 months), symptomatic ipsilateral stroke was not noted. One patient (7.1%) developed asymptomatic re-occlusion, but stent patency was preserved in 13 patients (92.9%).
CONCLUSION
CAS for CTO may be safe and feasible based on the mid- and long-term outcome.
目的
慢性颈动脉完全闭塞（CTO）的自然病程较差。既往报告提示颈动脉支架置入术（CAS）可改善CTO的临床结局。然而，其长期疗效尚未确立。本研究评估了CAS治疗CTO的中长期临床结局。
方法
我们评估了2010年9月至2019年10月期间15例行CAS治疗CTO患者的临床结局。
结果
再通的技术成功率为93.3%（15例患者中的14例）。8例患者使用自膨式支架治疗，6例患者使用自膨式冠状动脉支架治疗。2例患者（13.3%）出现与手术相关的有症状并发症。在随访期（平均34.9个月）内，未发现有症状的同侧卒中。1例患者（7.1%）出现无症状再闭塞，但13例患者（92.9%）支架保持通畅。
结论
基于中长期结局，CAS治疗CTO可能是安全可行的。
