(Neutral position pic.) Resting position with tourniquet: pectoralis muscle stretched by fixing the breast medially: venography was performed by injecting 20 mL of dilute contrast agent through the catheter, showing occlusion of the medial basilic vein and narrowing of the lateral.

However, when performing venography using a catheter inserted in the basilic vein (Figures 1 and 2), it showed no significant abnormality in resting position nor in Adson's maneuver with the arm elevation and 180-degree abduction.
Arm pulling. Dynamic venography with the arm pulled inferiorly and then released: venography was performed by injecting 40 mL of dilute contrast agent through the catheter, showing obstruction of the basilic/axillary veins and reflux and filling of the small cephalic vein providing collateral circulation filling the subclavian vein. The occlusion of the axillary vein was completely resolved upon releasing the tension. Findings of both pictures (Figures 1 and 2) in keeping with pectoralis minor syndrome on the right side. No venous compression at the costoclavicular space or the thoracic inlet.
