[MP-25] A successful case EVT for left subclavian artery in a patient with coronary subclavian steal syndrome

Yuji Matsuwaki (Nagoya Daini Red Cross Hospital)

Coronary subclavian steal syndrome (CSSS) is an uncommon complication after coronary artery bypass graft (CABG) surgery using the left internal mammary artery (LIMA). CSSS results from the retrograde blood flow through the LIMA graft in the left subclavian artery (SCA), consecutive to a proximal SCA stenosis or total occlusion. CSSS usually manifests as stable angina pectoris

A 78 years-old women presented with effort angina. For 10 years ago, Seven years ago, she had been diagnosed with two-vessel coronary artery disease and underwent CABG(LITA to OM, RITA to LAD).
Stress myocardial scintigraphy revealed redistribution in LCX territory. She underwent computerized tomography(CT) that showed stenosis of the left SCA.

The coronary angiography showed no significant interval changes of the two-vessel coronary artery disease. But the aortography showed stenosis of the proximal left SCA.
CSSS was suspected, and a balloon angioplasty followed by stenting (Express Vascular LD7.0/27mm), which was performed successfully. At the 1-year follow-up, the patient remained free from angina.
