obturator artery

A branch of the internal iliac artery; it runs along the inner wall of the pelvis and then leaves the pelvic cavity through the obturator canal. Its branches include the pubic artery.

The muscular branches of the obturator nerve and the medial circumflex femoral and obturator vessels ramify within and perforate these intermuscular fascial layers in order to supply the surrounding muscles.
The nerve branches of the posterior division of the obturator nerve were accompanied by the branches of the obturator vessels.
A triangular region bordered by the superior pubic ramus, posterior margin of the pectineus muscle and anterior aspect of the external obturator muscle containing the obturator vessels and nerve was defined and later used clinically to perform obturator nerve block with ultrasound guidance.
As a result, the contents of the obturator canal include anterior and posterior obturator nerve divisions directly related to the pubic groove, and the nerve to obturator externus muscle situated between the obturator vessels.
The presence of the obturator vessels alongside the obturator nerve divisions within the obturator canal may increase the risk of injury to these structures, for example during anesthetic procedures.
