Obturator arteryis frequently a branch of anterior division of internal iliac artery or one of the parietal branches of internal iliac artery. But it has attracted attention of pelvic surgeons and anatomists and radiologists because of the high frequency of the variation in its course and origin.

Artéria mesentérica inferior

The present report demonstrates obturator artery to be arising from the posterior division of internal iliac artery out of pelvises, a rare observation in Indian population. The variation is correlated developmentally and its clinical implications are also discussed.

Obturator artery; Anatomical variation. Vascular variations have always been a subject of controversy, as well as curiosity, because of their clinical significance. There is, perhaps, no artery of proportionate size having as variable an origin as that of the obturator artery OBAnor has any similar artery arterua greater attention among pelvic surgeons, anatomists and radiologists Pick etal.

Regarding the variability in the origin of OBA, it is documented that in The present case is an observation of unilateral variation in the origin of left OBA.

Origen Anómalo de la Arteria Obturatriz de la Arteria Iliaca Interna

The variant artery was arising from the posterior division of internal iliac artery, a rare observation in Indian population. Therefore an attempt has been made to highlight its clinical implications xrteria relation to the anomalous origin from the internal iliac artery. Out of pelvises of formalin fixed adult cadavers studied it was observed that in one adult male cadaver in the department of Anatomy of Vardhman Mahavir Medical College and Safdarjung hospital, New Delhi, the left obturator artery was arising from the posterior division of internal iliac artery.

The right side artery showed no variation of any sort, in its origin and course.

The course and branches of the variant OBA was observed till its exit from the obturator foramen and photographs were taken and labeled. The left OBA was found to be arising from the posterior division of internal iliac artery lying just medial to anterior division of internal iliac artery Fig.

It then traveled forwards, infero-lateral to the common trunk of internal pudendal and inferior gluteal artery, it further coursed forwards and downwards hipogasrica over the ischio-coccygeal part of levator ani to reach the upper part of obturator foramen, running parallel and inferior to the obturator nerve.

Medially it was related to the left ureter and ductus deferens. Throughout its course except near its origin it was related to the obturator fascia and obturator internus muscle laterally.

The rest of its branches didn’t show any variation. The total length of the left OB A was observed to be 7 lmm. It was given off at a distance of 8mm, from the point.

It gave one muscular branch at a distance of 44 mm, from its origin and a small branch tothe head of the femur. The right OBA was noted to be arising hipogastrlca the anterior division of the internal iliac artery and traveled along obturator nerve to reach the obturator foramen.

Its length was measured to be 54cm.

The obturator artery has been documented to be arising from all possible neighbouring arteries, i. Although similar same site of origin to the Raams et al’s findings, our observation of incidence of origin of left OBA is only 0. Further the exact site of origin has been documented in this study, which is at a distance of 8mm distal to the point of bifurcation of the internal iliac artery.

This rare abnormality in Indian population may be due different set of environmental or genetic factors. Thus influencing the development of pelvic vessels differently.

Arteria rectal inferior

The OBA arises comparatively late in development as a supply to a plexus which in turn is joined by the axial artery of lower limb that and accompanies the sciatic nerve Sanduno et al, It is currently accepted that the anomalies that affect the arterial patterns of the limbs are based on an unusual selection of channels from primary capillaries Arey.

The most appropriate channel enlarges whilst others retract and disappear thereby establishing the final arterial pattern Fitzerald, In this case of persistence of vascular channels in relation to the posterior division might have resulted in giving rise to OBA, whereas the vascular channels related to the anterior division of the internal iliac artery destined for the OBA got obliterated.

In the cases of ligation of the internal iliac arteries and their branches in women undergoing pelvic surgery, on postoperative angiography, it is seen that collateral channels start functioning soon after surgery Chait et al.

Also in cases of obstruction of the anterior division of internal iliac artery due to any cause, there will be sparing of OBA and its branches especially the branch to the head of femur.

The parietal branches of OBA are important collaterals in aortoiliac and femoral arterial occlusive diseases. Therefore this may be considered for a possible bypass grafting in cases of ischemic necrosis of head of femur following decreased blood flow through OBA, connecting the posterior division to the distal end of the obstruction. Moreover, the increased length of the left OBA, owing to the origin from the posterior division of internal iliac, may have an additional advantage while grafting.

Thus to avoid complications during surgery the radiologists and pelvic surgeons should be aware of this rare variation. The development of peripheral blood vessels.
