Fig 2 Relationships between left common iliac vein (LCIV) and the overlying arteries are shown in axial computed tomography projections at the level of L5. A, No compressive relationships are seen. B, The LCIV is compressed by the left common iliac artery (LCIA; arrow). C, The LCIV is compressed by the right common iliac artery (arrow). D, Both iliac arteries compress the LCIV (arrows).

Fig 3 Oblique-sagittal multiplanar reconstructions show the (A) “hourglass” profile and (B) “drop” profile deformation of left common iliac artery by a compressive right common iliac artery. In both cases, the lower portion of the vein (asterisks) is uncompressed. Journal of Vascular Surgery , 56S-61SDOI: ( /j.jvs ) Copyright © 2011 Society for Vascular Surgery Terms and Conditions

Fig 4 A, A 3-dimensional rotational venography clearly demonstrates the different impressions left by the common iliac arteries. At the right common iliac artery crossing, caliber reduction is orthogonal to the long axis of the left common iliac vein (LCIV; thick arrow). More distally, the compressive left common iliac artery (LCIA) left a longitudinal impression on the lateral half of the LCIV (thin arrows). By courtesy of Dr Wing Chan.17 B, The impression left by the LCIA on the lateral half of the LCIV is shown in a cadaveric sample (arrows).
