[A case of successful surgical retrieval of the intracoronary interlocked Palmaz-Schatz stent].

We presented a case of a 48-year-old male with failed delivery of the Palmaz-Schatz stent, who subsequently required CABG with successful retrieval of the stent. The patient had presented recurrent angina, approximately one and a half year since the last PTCA to the LAD. Re-PTCA was performed, but resulted in a severe local dissection. The stent implantation was tried, but was inadvertently dropped in the vessel. Since the patient was hemodynamically stable, we tried to remove the stent with Retriever endovascular snare, which ended up with interlocking the stent in the more proximal segment of the LAD and the snare itself was not removed. We, therefore, resort to the emergent operation, with successful retrieval of the snare device and the stent and carried on to the the bypass operation to the distal LAD without any complications. To our best knowledge, this is the first report in Japan for surgical retrieval of the Palmaz-Schatz stent, which was failed in delivery and interlocked in the vessel with retriever device.
