Using recently developed diagnostic and treatment methods, we successfully diagnosed and treated a case of subclavian steal syndrome. Syncope and left upper arm weakness suggested ischemia of the cerebral and left upper arm circulation. Volume-plethysmographic blood pressure measurements clarified the differences between the upper arms simultaneously. A high-resolution Doppler instrument revealed a retrograde left vertebral artery waveform, indicating subclavian steal syndrome. Aortography demonstrated proximal left subclavian artery occlusion. The patient was treated with stent implantation via a femoral approach using the latest equipment. Advances in diagnostic and treatment approaches for this syndrome are reviewed in connection with this case.
Summary: We present a case of subclavian steal syndrome successfully diagnosed using the latest technology and treated with stent implantation. The syndrome and its treatment are reviewed.
