Color Doppler images with the arm in the neutral (c) and in the abduction (d) positions showing significant stenosis with color aliasing in the compressed vein segment by the overlying pectoralis minor muscle. B-mode and color Doppler images of the axillary vein distal to the compression level showing the vein distension (e) with almost total cessation of the venous flow with the hyper-abduction (f)
