Thoracic outlet compression. Application of positional arteriographic and nerve conduction studies

Area of Science:

• Vascular Surgery
• Neurology
• Diagnostic Imaging

Background:

• Thoracic outlet compression syndrome (TOCS) presents diagnostic challenges.
• Conventional diagnostic methods for TOCS have limitations.

Purpose of the Study:

• To evaluate the utility of positional arteriography in TOCS diagnosis.
• To assess the diagnostic value of positional ulnar nerve conduction times in TOCS.

Main Methods:

• Review of positional arteriography findings in TOCS patients.
• Analysis of positional ulnar nerve conduction times in operated TOCS patients.

Main Results:

• Positional arteriography showed limited value in evaluating TOCS.
• Positional ulnar nerve conduction times were positive in 88% of operated TOCS patients.
• Cautious surgical approach is advised for patients with normal/elevated velocities.

Conclusions:

• Positional arteriography is not a primary diagnostic tool for TOCS.
• Positional ulnar nerve conduction times are a valuable addition to TOCS diagnostic armamentarium.
• Nerve conduction studies aid in diagnosing TOCS when symptoms are present.
