Patients with upper extremity DVT will typically present with arm swelling and prominent superficial veins.
Paget-Schroetter syndrome, also known as effort thrombosis, refers to primary thrombosis of the axillary and/or subclavian vein. It can be thought of as a venous equivalent of thoracic outlet syndrome. Central venous catheters and compression of the subclavian vein when it passes through the costoclavicular space are the most favored mechanisms of thrombosis. Upper extremity DVT may also occur due to an underlying condition such as certain cancers, trauma, or radiation therapy.
