Short answer · Medically reviewed summary · Last updated: 2026-05-08
Thoracic Outlet Syndrome (TOS) is most commonly referred to by its primary name, though it is historically and clinically known by several synonyms including neurovascular compression syndrome, cervical rib syndrome, and scalenus anticus syndrome. These various terms reflect the specific anatomical structures involved in the compression, such as nerves, arteries, or veins within the thoracic outlet. What are the common synonyms for Thoracic Outlet Syndrome? Because Thoracic Outlet Syndrome involves a complex set of structures, medical literature often uses specific names based on the primary site of compression or the historical discovery of the condition.

What are the common synonyms for Thoracic Outlet Syndrome?
Because Thoracic Outlet Syndrome involves a complex set of structures, medical literature often uses specific names based on the primary site of compression or the historical discovery of the condition. While Thoracic Outlet Syndrome is the standard term used today, you may encounter the following names in older records or specialized medical journals:
- Cervical Rib Syndrome: Often used when a congenital extra rib causes the compression.
- Scalenus Anticus Syndrome: Refers to compression occurring specifically between the scalene muscles.
- Costoclavicular Syndrome: Describes compression between the first rib and the clavicle.
- Hyperabduction Syndrome: Used when symptoms are triggered by arm elevation.
- Neurovascular Compression Syndrome: A broader term describing the impact on nerves and blood vessels.
Why does Thoracic Outlet Syndrome have multiple names?
The nomenclature for Thoracic Outlet Syndrome evolved as clinicians identified different anatomical "choke points" where the brachial plexus or subclavian vessels could be compressed. Historically, doctors named the condition after the specific structure they believed was causing the symptoms. Today, Thoracic Outlet Syndrome is the preferred clinical umbrella term, categorized into neurogenic, venous, and arterial subtypes.
How is this condition classified internationally?
In major medical classification systems, Thoracic Outlet Syndrome is consistently recognized under specific codes to ensure clinical accuracy. Under the ICD-10, it is typically coded as G54.0 (brachial plexus disorders). While it is not a singular genetic disorder found in OMIM, the condition is well-documented in clinical databases as a mechanical compression disorder.
