1) Describe normal anatomy and spectral Doppler of the vertebral arteries. 2) Describe the spectrum of Doppler findings of the subclavian steal phenomenon: pre, partial and complete steal. 3) Detect proximal disease in the innominate vessels and aorta using vertebral artery waveforms in combination with carotid waveforms.
This lecture will demonstrate normal and variant duplex Doppler imaging of the vertebral artery. It will analyze the anatomy of the vertebral-basilar circulation and how it explains the spectrum of subclavian steal syndrome. It will further demonstrate the combination of findings in vertebral and carotid circulations that indicates brachiocephalic disesase.
