The Use of Ultrasound in Diagnosing Thoracic Outlet Syndrome

In a recent case, point-of-care ultrasound was successfully used to diagnose venous thoracic outlet syndrome in a 46-year-old man presenting with left upper extremity swelling. The ultrasound revealed compression of the left subclavian vein under the clavicle, confirming the diagnosis. This demonstrates the potential of ultrasound in identifying vascular issues and assisting in the diagnosis of conditions affecting the upper extremities.
