Color Doppler imaging in the subclavian-axillary region and upper extremity

Area of Science:

• Vascular Imaging
• Medical Ultrasound

Background:

• Color-coded Doppler ultrasound is a non-invasive imaging technique.
• Assessing vascular structures in the thoracoaxillary region and upper arm presents unique challenges.

Purpose of the Study:

• To evaluate the utility of color-coded Doppler ultrasound in the thoracoaxillary region and upper arm.
• To assess the method's effectiveness in identifying vascular abnormalities, mapping veins, and evaluating grafts.

Main Methods:

• Thirty-three patients underwent color-coded Doppler ultrasound examination.
• The study focused on the thoracoaxillary region and upper arm vasculature, including subclavian vessels and cephalic/basilic veins.

Main Results:

• Subclavian artery and vein were visualized in most patients, with one case of occlusion and collateralization.
• Color-coded sonography improved speed of vessel localization and assessment of flow, turbulence, and collateralization.
• Masses, foreign bodies, and carotid subclavian grafts were accurately distinguished and evaluated.
• Sonographic mapping of cephalic/basilic veins was effective in seven patients.
• Foreign body detection was not significantly enhanced by color coding.

Conclusions:

• Color-coded Doppler ultrasound is a valuable tool for evaluating thoracoaxillary and upper arm vasculature.
• The technique offers advantages in speed, localization, and detailed assessment of vascular structures and abnormalities.
• It aids in identifying occlusions, collateralization, and grafts, improving diagnostic capabilities in this region.
