Thoracic outlet syndrome (TOS) is a complex and debated condition affecting patients of all ages but mostly in the younger patient group. Divided into three categories: Arterial, Venous and Neurogenic. While the first two are easier to prove the third one which is the commonest is difficult to diagnose or prove.
The condition is treated surgically by releasing the compression on the nerves and vessels mostly by resection of the first rib.
In a number of patients symptoms recur. After failing conservative treatment for recurrence, nerve release can be achieved by transecting the pectoralis minor muscle and releasing the tethered nerves like in the attached photos which can lead to symptoms relief (#vascularandwoundexpert).
