CORONARY-SUBCLAVIAN STEAL SYNDROME, TREATED BY BALOON-EXPANDABLE PERIPHERAL STENT. CASE REPORT

Patient K., male smoker, 65 years old, suffering from type 2 diabetes, adhering to basic therapy, in year 2018 underwent isolated internal mammary bypass surgery for coronary artery disease. In 2022, due to a deterioration in general well-being in the form of stabbing pains behind the sternum, shortness of breath during physical exertion, pain and numbness of the left upper limb, he was scheduled for coronary angiography with shuntography. During routine shuntography through the left radial access, the presence of retrograde filling of the LIMA graft was established, indicating the presence of the phenomenon of coronary-subclavian steal. Elimination of hemodynamically significant stenosis of the left subclavian artery with a peripheral balloon-expandable stent led to successful remodeling of left coronary hemodynamics, relief of angina symptoms, and restoration of adequate blood flow in the left upper limb in the early postoperative period.
