The purpose of the study was to evaluate the effect on the symptoms of transcatheter coil embolization of branches of the internal mammary artery.
In five patients with coronary steal syndrome that was caused by preferential flow in large unligated side branches of the internal mammary artery, coil embolization of the side branches was performed with use of a coaxial microcatheter.
Anginal symptoms disappeared in three patients and were substantially reduced in one patient following the radiologic intervention. In the fifth patient, who had concomitant stenoses of other coronary vessels, only a moderate change in symptoms was noted. No complications occurred.
In patients with internal mammary artery to coronary artery bypass who experience recurrent angina pectoris caused by preferential flow in large, unligated side branches of the internal mammary artery, repeat surgery may be circumvented or simplified by transcatheter coil embolization, which can help treat the angina.
本研究的目的是评估经导管线圈栓塞乳内动脉分支对症状的影响。
对5例因乳内动脉未结扎的大侧支血流优先导致冠状动脉窃血综合征的患者，使用同轴微导管对侧支进行线圈栓塞。
放射学干预后，3例患者的心绞痛症状消失，1例患者的症状明显减轻。在第5例伴有其他冠状动脉狭窄的患者中，仅观察到症状有中度变化。未发生并发症。
对于因乳内动脉未结扎的大侧支血流优先而经历复发性心绞痛的乳内动脉至冠状动脉搭桥患者，经导管线圈栓塞可避免或简化再次手术，有助于治疗心绞痛。
