A case of successful correction of subclavian steal syndrome by percutaneous transluminal angioplasty with stenting in a male patient who found incidentally significant interarm blood pressure difference. Small difference in blood pressure (BP) between two arms is a relatively common. Significant interarm BP difference is a potential marker of peripheral vascular disease such as subclavian artery stenosis and a predictor of cardiovascular disease. The subclavian steal syndrome is a condition that results from stenosis of subclavian artery proximal to the vertebral artery. The resulting symptoms are vertebrobasilar insufficiency symptoms due to reversal of blood flow from the contralateral vertebral and basilar artery into the ipsilateral upper extremity vessels and arm ischemic symptoms. Stenotic lesion of subclavian artery has traditionally been treated surgically. However recent trends are undergoing a paradigm shift from open surgery to endovascular approach. We report a patient with subclavian steal syndrome who found incidentally 35 mmHg interarm systolic BP difference. It was successfully treated by percutaneus transradial angioplasty with stenting on stenotic lesion of the subclavian artery.
