PURPOSE: To evaluate the use of color Doppler sonography in the diagnosis
of thoracic outlet syndrome. METHODS: We studied color Doppler sonographic
findings in 5 clinically suspected cases of thoracic outlet syndrome. The
subclavian artery and vein were studied in varying degrees of abduction to
assess the severity of the syndrome. RESULTS: Significant changes, i.e.,
stages of increased velocities, preocclusion, and occlusion in the
subclavian artery in varying degrees of abduction, were noted in 4 of 5
cases. Blunted flow in the axillary artery (4 patients) and a rebound
increase in velocities on release of abduction were noted in 3 patients.
These changes suggested that significant narrowing was causing symptoms.
CONCLUSION: Color Doppler sonography is a noninvasive, effective method
compared with digital subtraction angiography in the diagnosis of thoracic
outlet syndrome.
