There exists a wide spectrum of patient symptoms, which include vascular and/or neurologic signs. Neurogenic TOS accounts for most cases, whereas venous (2%–3%) and arterial TOS (1%) are relatively rare. Objective vascular studies such as venograms and arteriograms may identify signs of vascular compromise to aid in the diagnosis of arterial or venous TOS, but neurologic findings are more varied, and there is no single specific test to diagnose neurogenic TOS.
