His left lower limb was warm and mildly tender, associated with swelling up to the midthigh measuring 4 cm more than the right (Figure 1).
Ultrasound of left lower limb demonstrating (a) thrombosis involving the EIV, (b) failure of compressibility of CFV, and (c) no colour flow on duplex scan confirming the diagnosis of DVT. (d) CT of the patient showing the right CIA (white arrow) compressing the left CIV against the lumbar vertebrae (black arrow).

Doppler compression ultrasonography of the left lower limb showed partial DVT extending from the external iliac (EIV), common femoral (CFV), to the popliteal veins (Figures 2(a)-2(c)).
Intraoperative venogram (a) demonstrated extensive intravenous thrombus in the CFV and proximal SFV. Uninterrupted contrast flow through the CIV after (b) AngioJet pharmacomechanical thrombolysis/thrombectomy and (c) iliac vein stenting upon completion of the procedure.

Intraoperative venogram demonstrated extensive intravenous thrombus from the left CIV to proximal superficial femoral vein (SFV) (Figure 3(a)). There was uninterrupted contrast flow through the left CIV upon completion of the procedure (Figures 3(b)-3(c)) with resolution of the compression and increased CIV cross-sectional area (~198 mm2) on IVUS.
