Back ground and Aims: The variations in the origin of the parietal branches of the internal iliac artery are of great clinical importance during pelvic surgeries, but still now a detailed study had not been done in Andhra Pradesh state, it was decided to undertake this present study. Isolation of internal iliac artery and tracing of the major parietal branches were done to know more about it than already documented and thereby hoping to add more information to guide the radiologists and operating surgeons. Materials and methods: A total of 45 pelvic halves had been studied after a clear dissection and observed for the variations of major parietal branches of the internal iliac artery (The superior gluteal, inferior gluteal, and internal pudendal artery) based on adachi types. Results: Among the 45 pelvis halves based on adachis classification Type I: 66.68%, Type II: 2.22%, Type III: 24.4%, Type IV: 4.44% and Type V: 2.22%. Conclusion: The present findings showed a higher incidence from the common trunk of inferior gluteal-internal pudendal arteries than previous studies. The findings noted in the present study regarding the parietal branching pattern of internal iliac artery had contributed to a better understanding of the branching pattern of this important vessel and will prove definitely useful to clinicians in their respective fields.
