目的 探讨冠状动脉-肺动脉瘘的DSA表现及栓塞治疗的疗效。 材料与方法 经股动脉插管选择性冠状动脉造影，分析冠状动脉-肺动脉瘘的DSA表现，经确诊后采用聚乙烯醇颗粒及软钢丝栓塞。 结果 9例冠状动脉-肺动脉瘘均被造影所证实。2例较粗大的瘘，分别3次用聚乙烯醇泡沫栓塞及软钢丝栓塞，再次选择性冠状动脉造影显示冠状动脉-肺动脉瘘完全被阻塞。 结论 选择性冠状动脉造影是诊断冠状动脉-肺动脉瘘的最佳方法。对较大的瘘，临床有症状者可用介入栓塞治疗，其操作简单、创伤小、安全可靠、预后佳，是一种较理想的治疗方法。“,”Objective To study DSA manifestations of coronary-to-pulmonaryartery shunt, and to assess the effectiveness of embolization therapy. Materials and Methods DSA findings in 9 patients with coronary-to-pulmonary artery shunt, diagnosed with selective coronary angiography, were analyzed, and embolization therapy with polyvinyl alcohol particles and soft steel wire was made. Results Of 9 patients, 2 had larger shunt, which was embolized three times with polyvinyl alcohol particles and soft steel wire. After the procedures, selective angiography confirmed that the shunt was completely occluded. Conclusion Selective coronary arteriography is of first choice for diagnosing coronary-to pulmonary artery shunts. Embolization is a safe and minimum-invasive therapy, and it should be adopted in symptomatic patients with larger shunt.
