摘要(Abstract):
目的探讨经导管介入封堵冠状动脉瘘(CAF)的中期效果及冠状动脉CT血管造影(CTA)在随访中的价值。方法回顾性分析2012年7月至2018年8月在徐州医科大学附属医院行经导管介入封堵的12例CAF患者,根据瘘口大小、起源、引流位置、分流量多少以及冠状动脉迂曲或扩张程度选取封堵器材,术后定期随访心电图、超声心动图及冠状动脉CTA,对术后临床疗效及CTA结果进行分析。结果 12例患者均封堵成功,其中2例患者合并冠状动脉重度狭窄,同期行经皮冠状动脉介入治疗(PCI),术后重复造影示封堵完全,无明显残余分流。术后中位随访时间为3.5年(1个月~6年)。所有患者均复查超声心动图,未见明显残余分流,心功能良好(NYHA心功能分级Ⅰ~Ⅱ级)。8例患者复查冠状动脉CTA,其中2例大型右冠状动脉左心室瘘患者出现血栓形成,另1例多发冠状动脉-肺动脉瘘仍有微量残余分流,余无明显并发症发生。结论经导管介入封堵CAF中期随访结果示封堵效果良好,但应警惕供血冠状动脉血栓形成及残余分流的风险。冠状动脉CTA能清晰显示冠状动脉血管解剖结构、封堵器位置以及有无残余分流等,在术后随访中具有重要诊断价值。
