Postural compression of subclavian vein in droopy shoulder syndrome--a case report.

A patient with droopy shoulder syndrome (DSS) presented postural symptoms of venous compression of the left upper limb, in addition to those of traction at the brachial plexus. An antegrade phlebography clearly demonstrated impaired patency of the subclavian vein on neck extension. Recognition and management of the compromised venous drainage in patients with DSS is important in preventing vascular complications of the upper limbs.
