What are the types of thoracic outlet syndrome?
- Neurogenic TOS occurs when the nerves leading from the neck to the arm (the brachial plexus) is compressed.
- Venous TOS occurs when a vein is compressed, leading to upper body thrombosis.
- Arterial TOS occurs when an artery is compressed.
What does Adson’s test mean?
Adson’s test is a provocative test for Thoracic Outlet Syndrome accompanied by compression of the subclavian artery by a cervical rib or tightened anterior and middle scalene muscles.
What does a positive Adson’s test mean?
A positive test is indicated by an absence or decrease in vigor of the pulse and implies possible costoclavicular syndrome. It is also positive if the client experiences an increase of neurologic symptoms into the upper extremity on that side.
What are the 3 types of TOS?
Can you have all 3 types of TOS?
Thus, the three classic types of TOS are arterial TOS, venous TOS, and neurogenic TOS. To clarify, each of the three types of TOS is defined by the vital structure that is compressed in the thoracic outlet: Subclavian Artery: Arterial TOS. Subclavian Vein: Venous TOS.
What does Adson’s test for?
Purpose. Adson’s test is a provocative test for Thoracic Outlet Syndrome accompanied by compression of the subclavian artery by a cervical rib or tightened anterior and middle scalene muscles.
What is the Costoclavicular test?
Patient is standing. The examiner palpates the radial pulse and then draws the patient’s shoulders down and back as the patient lifts their chest in an exaggerated “at attention” posture. A positive test is indicated by an absence or decrease in vigor of the pulse and implies possible costoclavicular syndrome.
What happens if TOS is left untreated?
If left untreated, TOS can cause complications, such as: Permanent arm swelling and pain (especially in patients with venous TOS) Ischemic ulcer of the fingers (open sore caused by reduced blood flow) Gangrene (the death of body tissue, often caused by a loss of blood flow)
