Vein Graft Coil Embolization and Successful Retrieval With a Micro-Snare.

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. [ABSTRACT FROM AUTHOR]
