Retrieval of occluding unexpanded Palmaz-Schatz stent from a saphenous aorto-coronary vein graft.
The Palmaz-Schatz coronary stent is used frequently to reduce the rate of restenosis of balloon angioplasty in saphenous vein grafts. In many European centers, the stent, manually crimped on a balloon, is advanced across the stenosis without a protective sheath. This report describes a patient in whom an attempt to deploy a stent in the orifice of a saphenous vein graft was complicated by dislodgement of the unexpanded stent from the balloon. The unexpanded stent caused immediate occlusion of the vein graft and severe ischemic symptoms. The stent was retrieved by inflation of another balloon in the graft, distal to the stent, pulling the balloon toward the guiding catheter, and then withdrawing the whole system.
