Intraoperative subclavian artery stenting to salvage a LIMA graft

The internal mammary artery is the preferred conduit for coronary bypass grafting; however, suboptimal flow through the internal mammary artery is sometimes found during the operation, and the conduit is abandoned. Subclavian artery stenosis, a well-recognized cause of reduced internal mammary artery flow, is easily and effectively treated with endovascular techniques. We describe a case of intraoperative primary stent deployment in a high-grade subclavian artery stenosis compromising internal mammary artery flow.
