In the first instance, this occurred at the obturator foramen on emergence into the thigh, where the posterior division is framed by the branches of the obturator artery and vein, and is crossed by the anastomosing vein between the anterior and posterior branches of the obturator vein.
At the level of the obturator canal/foramen, a lesion (e.g., obturator hernia) of the posterior division of the obturator nerve could also entrap the obturator artery or its branches.
Further, the inferior epigastric artery frequently arises indirectly from external iliac artery as from a common trunk with other arteries such as deep circumflex iliac artery, the obturator artery (Kawai et al., 2008 & Hussein et al., 2013) or with the obturator and medial circumflex femoral arteries (Sanudo et al., 2011).
