title: Crush stenting of bifurcational left subclavian-vertebral artery stenosis.
abstract: Left internal mammary artery (LIMA) has the best long-term patency in patients undergoing coronary artery bypass surgery. Stenosis of the proximal left subclavian artery (SA) may reduce flow to the LIMA, causing myocardial ischemia. We report a novel technique (crush stenting) for the treatment of a complex bifurcational left SA-vertebral artery (VA) stenosis in the presence of a patent LIMA bypass conduit. This technique limited plaque shifting, restored normal flow to all vessels, including the LIMA, and avoided devastating consequences of VA occlusion.
