Medical Definition

TOS

abbreviation

thoracic outlet syndrome

The diagnosis of thoracic outlet syndrome (TOS) is intrinsically difficult … . Symptoms may arise due to compression of neural and/or vascular elements in one or more of three different locations.

—John E. Skandalakis and Petros Mirilas, The American Surgeon

Reported success of conservative therapy varies, but most studies find that the majority of patients with TOS achieve significant relief from nonsurgical intervention.
