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