15 — Duplex Imaging of the Upper Extremity Venous System
241
2. You are asked to perform an examination on a patient with a dressing in place over the subclavicular region on the shoulder. What specifically can you do to provide adequate information for determining upper extremity venous system patency?
3. You are examining a patient for an upper extremity venous thrombosis. You notice several dilated chest wall veins. The spectral Doppler signals from both subclavian and internal jugular veins are antegrade but continuous. What is the likely cause of these findings?
