Oh, the pancoast tumor is compressing the superior cervical plexus above T1 causing Horner syndrome which is miosis, ptosis and anhidrosis

The superior vena cava syndrome is a compression of the cava as the name says and it will reflect enlarged of the vein over the neck, erythema facial, dyspnea an swelling. Must of the time 85-90% caused by small cell ca.

As i told you 85-90% of the causes of SVC SYND are Small Cell Ca > Adenoca > Epidermoid CA of Lung. The different with the Horner Syndrome is the location because Horner syndrome is a tumor arising Superior Sulcus over the Cervical Plexus... above t1. And Clx they are Different as i told you...

The Thoracic Outlet Syndrome is defined any obstruction over the Thoracic Outlet Space, which is a variaty of 4 clinical signs...

1. True Neurological Sympton 98 % because of the compresion of the cervical root. Pain Irradiating from the base of the nect to the shoulders and arms. Atrophy of the Hypothenar Region.

2. Compresion of the Venous, 1.5 % The subclavian Causing cyanosis, edema and swelling. Trombosis may occur.

3. Arterial Compresion 0.5 % Subclavian Arterie. Coldness and pallor.

4. Postural Variaty ...

...... Nothing else i can remember... Hope this help...

Are you sure about compression of the veins in thoracic outlet syndrome? I may be wrong but from what I remember, veins are not compressed because they pass from above the scalenus anterior. Please do explain if it is otherwise.
