Obturator vein

The obturator vein travels between the adductor region of thigh and internal iliac vein entering the pelvis through the obturator foramen (along with the obturator artery and obturator nerve).

Course and termination

Along the pelvic side wall the vein travels between the ureter and the internal iliac artery before terminating by draining into the internal iliac vein. A cadaveric study of 150 hemi-pelvises found the obturator vein to be the most inferior structure of the obturator neurovascular bundle in 47% of specimens.

Variation

An enlarged pubic vein may replace the obturator vein.
