Imaging Procedures and Findings
A 25-year-old man complained about upper extremity claudication & diminished pulses months after car accident, evaluated about TOS using angiograghy (DSA). Performed DSA showed right subclavian artery cut off at about clavicule (fractured at previous trauma), collaterals & also run off.
The most common causes of subclavian artery occlusion are atherosclerosis (30%) & emboli (most common from cardiac origin). Other causes are: arterial dissection, neoplasm (e.g., Pancoast tumor), trauma (blunt or penetrating, iatrogenic), scar (e.g., post radiation, fibrosing mediastinitis), thoracic outlet syndrome, fibromuscular dysplasia, vasculitis , congenital absence of subclavian artery (rare).
