- “ Thoracic outlet syndrome (TOS) refers to compression of the neurovascular bundle as it crosses through the thoracic inlet.”

AJR 2013; 201:753-763 - Thoracic Outlet Syndrome: Facts
- Clinical presentation is pain, tingling, weakness, or other symptoms of the ipsilateral upper extremity
- The syndrome may be caused by neurogenic, arterial, venous or combined causes although the neurogenic cause is most common
- Arterial involvement can be diagnosed by CT with arm in both abduction and the neutral position - “ CTA plays a significant role in the planning of complex arterial surgical reconstructions where upper extremity arterial mapping is needed.”

AJR 2013; 201:753-763 - “ Traditionally, vascular mapping is performed with duplex ultrasound, but CTA and MRA may be performed for more anatomic imaging.”

AJR 2013; 201:753-763 - “ Complications of dialysis access are typically diagnosed with DSA and ultrasound. However, CTA has also been shown to reveal complications such as arterial steal,aneurysm formation, stenoses, and occlusions.”

AJR 2013; 201:753-763 - “ CT angiography has become an important diagnostic imaging modality for the evaluation of upper extremity vascular pathologic abnormalities. The attractiveness of upper extremity is 24 hour availability, rapid acquisition, minimal invassiveness, and the display of both vascular and musculoskeletal structures.”
