case_images: Initial assessment with duplex venous ultrasound of the right upper extremity demonstrating thrombi with resultant partial or no Doppler flow in the subclavian (a), axillary (b), paired brachial (top patent, bottom occluded) (c), and basilic (d) veins.

case_images: Initial duplex venous ultrasound of the RUE revealed extensive thrombus involving the right subclavian, axillary, brachial, and basilic veins (Figure 1).
case_images: (a) Pre-lysis venogram showing decreased flow and engorgement of the upper extremity veins. (b) Post-lysis venogram demonstrating restored patency. (c) Pre-lysis venogram with arrow pointing to thrombus with collateral drainage. (d) Arrow shows outflow through the normal veins with decreased (but persistent) collaterals following lysis. (e) Venogram of right subclavian vein 2 months post-first rib resection surgery and repeat venoplasty showing patent flow without stenosis.

case_images: A pre-lysis venogram was performed (Figure 2(a) and (c)). Approximately 20 h after initiating catheter-directed thrombolysis, he returned to the interventional radiology suite where post-lysis RUE venogram showed resolution of the previously seen thrombi (Figure 2(b) and (d)). He underwent repeat venoplasty of the right subclavian vein, resolving the stenosis (Figure 2(e)).
