Abstrakt: This report describes the case of a 63-year-old asymptomatic patient presenting findings compatible with partial subclavian steal syndrome on color Doppler ultrasound of the carotid and vertebral arteries. The ultrasonic analysis of the cervical vessels showed no apparent cause to justify the subclavian steal. Computed tomographic angiography of the thoracic aorta showed left subclavian artery kinking proximal to the origin of the vertebral artery, an extremely rare finding that led to the subclavian steal. The patient underwent conservative treatment.
