A Case of Endovascular Treatment of Subclavian Artery Stenosis Resulting in Recovery of LITA-LAD Graft Flow

Abstract

A 59-year-old man presented with left upper limb ischemia and significant hypotension. He had undergone coronary artery bypass grafting using a left internal thoracic artery (LITA) graft 18 years previously. Angiography revealed stenosis of the left subclavian artery and visualization of only the proximal half of the LITA. Complete recanalization of the left subclavian artery was achieved by an endovascular treatment, and the left anterior descending artery distributing from the LITA became well visualized.
