THORACIC OUTLET SYNDROME

TOS has been classified into 3 categories based on etiology, symptoms, clinical presentation, or anatomy:

1. Arterial TOS (1%; digital ischemia, claudication, typically related to a cervical rib)

2. Venous TOS (2-3%; due to subclavian vein obstruction from thrombosis/scarring, UL swelling is common)

3. Neurogenic TOS (95%; brachial plexus is compressed; paresthesia and pain in the neck, shoulder, and arm are common; symptoms are worse with overhead motion)

4. Demonstrate using the Roos & Adson tests.
