Summary

Thoracic outlet compression involves the brachial plexus, subclavian artery, and subclavian vein. These structures can be compressed in three key spaces due to anomalies or trauma.

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Neurology

Background:

  • The thoracic outlet is a critical anatomical region.
  • It transmits the brachial plexus, subclavian artery, and subclavian vein.
  • Compression in this area can lead to significant neurovascular compromise.

Purpose of the Study:

  • To delineate the anatomical spaces within the thoracic outlet.
  • To identify potential sites for neurovascular compression.
  • To understand the etiology of thoracic outlet syndrome.

Main Methods:

  • Anatomical review of the thoracic outlet.
  • Identification of the interscalene triangle, costoclavicular space, and subpectoral space.
  • Analysis of potential compression mechanisms.

Main Results:

  • Three primary spaces were identified: interscalene triangle, costoclavicular space, and subpectoral space.
  • The brachial plexus, subclavian artery, and subclavian vein traverse these spaces.
  • Compression can arise from structural anomalies or traumatic injury.

Conclusions:

  • Understanding thoracic outlet anatomy is crucial for diagnosing compression.
  • The three identified spaces are key locations for potential neurovascular compromise.
  • Etiologies include congenital anomalies and acquired trauma.
