Abstract

Introduction: Obturator artery (OA) is a branch of anterior division of the internal iliac artery (IIA). It is accompanied by the obturator vein (OV) which terminates into the internal iliac vein (IIV). In about 20-25% cases, OA arises from the inferior epigastric artery (IEA) instead of the internal iliac artery (EIA) and then it is called an abnormal obturator artery (AOA). Normally we do not find a venous plexus on the lateral wall of the pelvis. Case report: We report the presence of an AOA arising from IEA. AOA was accompanied by an abnormal obturator vein (AOV) which terminated into the inferior epigastric vein (IEV). In addition, there was a normal OV accompanying the obturator nerve (ON). It terminated by opening into the internal iliac vein (IIV). Further there was a prominent venous plexus in relation to the anterolateral wall of the pelvis. This plexus communicated with prostatic and vesical venous plexuses anteriorly; inferior epigastric vein (IEV) and external iliac vein (EIV) superiorly; and OV posteriorly. Conclusion: Knowledge of presence of AOA is very handy in reducing the strangulated femoral hernia. Knowledge of possibility of an abnormal venous plexus on the lateral pelvic wall is important in pelvic surgeries.
