Presented herein is a clinical case report concerning the formation of vertebral-subclavian steal syndrome combined with occlusion of the left subclavian artery and an abnormal origin of the left vertebral artery from the aortic arch. Duplex scanning data and angiography findings showed that the collateral compensation of haemocirculation in the upper extremity took place through the subclavian-vertebral collateral net. Doppler ultrasonography signs of the latent steal syndrome were revealed in the intracranial segment of the left vertebral artery and were confirmed by the findings of the reactive hyperthermia test. Balloon angioplasty with stenting of the 1st portion of the left subclavian artery resulted in normalization of the Doppler spectrum in the intracranial segment of the left vertebral artery.

KEY WORDS: vertebral-subclavian steal syndrome, collateral compensation, duplex scanning, subclavian artery stenting.
