First rib resection in thoracic outlet syndrome

Area of Science:

• Vascular Surgery
• Neurology
• Anatomy

Background:

• Thoracic outlet syndrome (TOS) commonly presents with exercise-induced upper extremity paresthesia.
• Neurogenic TOS, involving brachial plexus compression, is the most frequent type.
• Vascular compromise, though less common, can affect the subclavian artery or vein.

Purpose of the Study:

• To review the pathophysiology of TOS.
• To describe effective surgical interventions for TOS.
• To highlight the role of first rib resection in TOS treatment.

Main Methods:

• Review of existing literature on TOS pathophysiology and surgical treatments.
• Analysis of surgical decompression techniques, focusing on first rib resection.
• Discussion of supraclavicular and transaxillary approaches for first rib resection.

Main Results:

• First rib resection is a key component of surgical treatment for TOS.
• Surgical decompression effectively addresses brachial plexus compression.
• Both supraclavicular and transaxillary routes are viable for first rib resection.

Conclusions:

• Complete first rib resection is essential for surgical management of TOS.
• Surgical intervention should be considered for TOS patients unresponsive to conservative care.
• Transaxillary first rib resection is a preferred surgical approach.
