Thirty-three patients were examined by color-coded Doppler ultrasound
of the thoracoaxillary region or upper arm to review the utility of th
e method in this local area. The subclavian artery and vein were ident
ified in all but one patient, in whom the subclavian vein was occluded
and collateral vessels had developed. Masses and foreign bodies were
easily distinguished from vascular abnormalities. Sonographic cephalic
/basilic vein mapping was effective in seven patients. Carotid subclav
ian grafts were noted and evaluated appropriately in two patients. Col
or-coded sonography offered advantages in speed of localization of ves
sels and visual assessment of vessel location, direction of flow, turb
ulence, relationship to adjacent soft tissues, and detection of collat
eralization. Foreign body detection was not enhanced by color coding.
