经导管介入治疗冠状动脉瘘

目的：探讨经导管介入治疗冠状动脉瘘的方法及临床疗效。方法：经导管堵塞冠状动脉瘘14例，平均年龄7．1岁。结果：13例应用弹簧圈堵塞，平均瘘口大小为3．65mm，除3例失败外均获成功；1例（瘘口6．6mm）应用Amplatzer动脉导管未闭堵塞器堵塞成功。所有病例随访1个月－4年，均无残余分流及任何并发症。结论：经导管介入治疗冠状动脉瘘具有良好的临床疗效及安全性。可控弹簧圈一般用于堵塞瘘口较小的冠状动脉瘘，而瘘口较大的冠状动脉瘘可选用Amplatzer动脉导管未闭堵塞器。

Transcatheter occlusion of coronary artery fistula with coils or Amplatzer PDA occluder

Objective To explore the methodology and efficacy of transcatheter closure of coronary artery fistula with coils or Amplatzer PDA occluder Methods 14 patients with coronary artery fistula underwent transcatheter closure and their mean age was 7 14 years.Left and right catheterization,left ventriculography, ascending aortography and selective coronary angiography were performed to assess anatomic types of coronary artery fistula, size of fistula,routes of fistula and branches.Appropriate occluding devices (coils or Amplatzer PDA occluder) were selected. Results 13 patients underwent transcatheter closure with coils(Cook corporation).Their mean size of fistula was 3 84 mm Procedures were successful in all patients except 3 patients One patient(size of fistula is 6 6 mm)underwent transcatheter closure with Amplatzer PDA occluder(AGA corporation)with good results.During the follow-up period of 1 months to 4 years,no residual shunt occurred and no complications were observed Conclusion Transcatheter intervension of coronary artery fistula is safe and efficient.The detachable coils can be used for occlusion of small coronary artery fistula and Ampltzer PDA occluder can be used for occlusion of large coronary artery fistula
