Results: The gastroduodenal (GDA), anterior superior pancreaticoduodenal (ASPD), and anterior inferior pancreaticoduodenal (AIPD) artery was found in all the cases, whereas the posterior superior pancreaticoduodenal (PSPD) and posterior inferior pancreaticoduodenal (PIPD) artery was present in 93.34% cases. The ASPD artery originated from GDA in all the cases. Two types of variations were observed in the origin of PSPD artery and four types each in the origin of AIPD and PIPD artery. Anatomical and numerical variations were observed in both anterior and posterior arches, posterior arch being absent in 20% cases.
