Implications of Costoclavicular Ligament Resection

The implications of costoclavicular (CA) ligament resection on the subclavian artery can be understood through various studies that have examined the effects of this procedure on thoracic outlet syndrome (TOS) and the subclavian artery.

  • The study by 1 discusses the treatment of thoracic outlet syndrome, including the resection of the costoclavicular ligament, and notes that this procedure can help alleviate compression on the subclavian artery.
  • Another study by 2 highlights the importance of preserving or reconstructing the costoclavicular ligament during resection of the medial portion of the clavicle to obtain a satisfactory result.
  • The research by 3 investigates the narrowing of the subclavian vessels during shoulder abduction and finds that the costoclavicular space is a significant area of compression, which can be relevant to understanding the implications of CA ligament resection.
  • A case study by 4 reports on the use of a combined endovascular and surgical approach, including first rib resection, to treat thoracic outlet syndrome complicated by an aneurysm of the subclavian artery, demonstrating the potential benefits of decompressing the costoclavicular space.
  • Furthermore, an anatomical study by 5 emphasizes the importance of the costoclavicular space in possible compression of the subclavian artery, suggesting that this area should be considered during surgical decompression for TOS.

Key Findings

Key findings from these studies include:

  • The costoclavicular ligament plays a role in the compression of the subclavian artery in thoracic outlet syndrome 1, 5.
  • Resection of the costoclavicular ligament can help alleviate this compression 1, 4.
  • Preservation or reconstruction of the costoclavicular ligament is important for obtaining a satisfactory result in certain surgical procedures 2.
  • The costoclavicular space is a significant area of compression for the subclavian artery during shoulder abduction 3.
  • Decompression of the costoclavicular space, including resection of the costoclavicular ligament, can be an effective treatment for thoracic outlet syndrome complicated by subclavian artery compression or aneurysm 4.
