Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [1] There are three main types: neurogenic, venous, and arterial. [1]
Thrombolysis is typically performed prior to first rib resection for venous thoracic outlet syndrome. First rib resection is indicated for venous , arterial , and neurogenic TOS. [ 1 ] In all cases, the goal of the operation is to increase the dynamic space between the chest wall and the clavicle , through which the subclavian vein, artery, and ...
Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
thoracic outlet syndrome Wright's test is a clinical sign in which the radial pulse weakens or disappears when the arm is abducted and externally rotated . [ 1 ] [ 2 ] It occurs in some patients with thoracic outlet syndrome .
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
Thoracic outlet syndrome: Occurs when nerves or blood vessels are compressed in the space between the first rib and the collarbone, causing symptoms such as pain in the neck, shoulder, or chest, along with arm weakness or numbness [41] Adverse effect from certain medications
In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option for peripheral nerve pain. [1] Despite treating the underlying cause of the disease, the symptoms may not be fully reversible as delays in diagnosis can allow permanent damage to occur to the nerve ...
thoracic outlet syndrome Adson's sign is the loss of the radial pulse in the arm by rotating head to the ipsilateral side with extended neck following deep inspiration. It is sometimes used as a sign of thoracic outlet syndrome (TOS). [ 1 ]
