Abstract
We examined the usefulness of color-coded Doppler echography for evaluating hemodynamics in patients with subclavian steal syndrome. Eighteen patients with subclavian steal syndrome, aged 54 to 77 years, were investigated. The diagnosis was confirmed by conventional angiography and pulsed-wave Doppler sonography. Using color-coded Doppler echography, the common, internal and external carotid and vertebral arteries and the subclavian artery on the affected side were visualized. In all patients, color-coded images of the antegrade common carotid arterial flow and the retrograde vertebral arterial flow on the affected side were obtained. Rapid flow through stenotic lesions and reflux from vertebral to subclavian arteries at the vertebral arterial ostia were observed. Color-coded Doppler echography is superior to duplex echography without the color-coded mode, because the flow through the affected vertebral and subclavian arteries can be easily traced in detail and the images are persuasive. This method is beneficial for diagnosing subclavian steal syndrome.
