Abstract
Background: Obturator artery is one of the medium sized parietal branches of the anterior division of internal
iliac artery and it supplies the medial side of the thigh. It is the most variable vessel among the branches of the
internal iliac artery. Materials and Methods: The present study was conducted on a total of 45 pelvic halves had
been studied. The material consisted of adult subjects between the ages of forty and eighty five, from the
dissection hall of department of anatomy of Alluri Sitarama Raju Academy of Medical Sciences, Eluru, and
Andhra Pradesh. The findings were observed and recorded. Results: Origin of obturator artery was most frequently
a direct branch of the anterior division of the internal iliac artery, in 16 specimens (35.55%). It was
arising from the inferior epigastric artery in 12 specimens (26.66%). It arose from the common trunk of inferior
gluteal and internal pudendal artery in 6 specimens (13.33%) etc. Conclusion: The variations in obturator
artery may lead to surgical complications during pelvic surgeries requiring suturing along the pelvic brim. The
anomalies affecting the arterial patterns of the limbs are based on unusual selection of channels from primary
capillaries. The most appropriate channel enlarges, whilst the others retract and disappear, thereby establishing
the final arterial pattern and resulting in variations in the origin. Prior knowledge of the anatomical variations
may be beneficial for vascular surgeons ligating the internal iliac artery or its branches and the radiologists
interpreting angiograms of the pelvic region.
