Figure 2. Longitudinal ultrasound scan of the LCIV and common iliac arteries. (A) Measurement of minimum distances (a: 2.4 mm) between the RCIA (arrow heads) and the vertebral spine. Arrow indicates the thrombotic tract of the LCIV. (B) Measurement of minimum distances (a: 1.8 mm) between the LCIA (arrow heads) and vertebral spine. Arrow indicates the LCIV. (C) Duplex Doppler ultrasound for measurement of PSV in the pre-stenotic tract of the LCIV. Arrow indicates right common iliac artery. (D) Duplex Doppler ultrasound measurement of PSV in the post-stenotic tract of the LCIV. Arrow indicates left common iliac artery. LCIV – left common iliac vein; LCIA – left common iliac artery; RCIA – right common iliac artery; PSV – peak speed velocity.
