Following successful retrograde CTO PCI via a degenerating saphenous vein graft, persistent TIMI II flow was noted in the graft. Given increased risk of target vessel failure in the presence of significant competitive flow from a saphenous vein graft, the SVG underwent coil embolization with two 4 mm × 6 cm detachable coils. Follow up angiography with forceful contrast injection resulted in embolization of the coils into the patient's two remaining patent grafts. The coils were then retrieved using a micro-snare. The patient tolerated the procedure with no compromise of flow into the remaining grafts and resolution of angina following CTO PCI.
经退化的大隐静脉桥成功逆行 CTO PCI 后，桥内持续 TIMI II 级血流。鉴于大隐静脉桥存在显著竞争血流时靶血管失败风险增加，对 SVG 进行了双枚 4mm×6cm 可脱卸弹簧圈栓塞。在强力造影剂注射进行随访造影时，弹簧圈栓塞到患者其余两条通畅的桥内。随后使用微圈套器取出弹簧圈。患者术中耐受良好，无剩余桥血流受损， CTO PCI 后心绞痛缓解。
