Thoracic Outlet Syndrome Testing
Thoracic Outlet Syndrome (TOS) testing evaluates the compression of nerves and blood vessels in the area between the collarbone and first rib. This assessment is crucial for diagnosing vascular and neurogenic TOS, guiding treatment, and monitoring patient outcomes.
TOS is a condition caused by compression of the brachial plexus nerves and/or subclavian vessels as they pass through the thoracic outlet. Symptoms may include pain, numbness, and impaired blood flow to the arm and hand.
- Can be neurogenic, venous, or arterial in origin
- Often triggered by certain arm positions or activities
- Requires specialized vascular testing for diagnosis
TOS testing involves measuring blood flow and nerve function in the arm during various provocative maneuvers. Blood pressure cuffs, Doppler, and PPG sensors are used to detect changes in circulation and waveform patterns that indicate compression.
- Provocative maneuvers (e.g., Adson's, Roos, Wright's tests)
- Real-time monitoring of blood flow and waveforms
- Automated data capture and analysis
TOS testing is invaluable for:
- Diagnosing vascular and neurogenic TOS
- Guiding surgical and non-surgical treatment
- Monitoring post-intervention outcomes
- Supporting early intervention and improved quality of life
These tests are recommended in clinical guidelines for comprehensive vascular assessment and are a mainstay in vascular labs.
VasoGuard systems streamline TOS testing with automated workflows, high-precision sensors, and intuitive software. Clinicians benefit from real-time data, comprehensive reporting, and seamless integration with EMR systems.
- Automated multi-site measurement
