Anatomy Explains Symptom Variety
- The thoracic outlet is the passage between the lower neck and top of the chest carrying the brachial plexus and subclavian vessels.
- Compression here produces pain, numbness, weakness, swelling, or circulatory change depending on the structure involved.
Three Distinct TOS Types
- TOS splits into neurogenic, venous, and arterial forms with different prevalences and risks.
- Neurogenic is most common; arterial is rare but can cause severe ischemia needing urgent care.
Refer Vascular Signs Immediately
- Look for swelling, heaviness, bluish discoloration, or distended veins to suspect venous TOS.
- Refer urgently for vascular assessment if you see cool, pale limbs, diminished pulses, or fingertip ischemia suggesting arterial TOS.
