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.

Conclusions: In the present study, an attempt was made to systematically describe the individual arterial configurations of the PD complex. The information provided here has important implications for preoperative planning of technically challenging surgeries and interventions around the pancreatic head.

Abstract: The complex arterial system makes pancreatic interventions technically challenging for surgeons, and interventional radiologists. The arterial variants may alter tumor resecability, and cause complications in arterial embolization. International data on pancreatic blood supply are variable; therefore, we aimed to determine the frequency of variants of pancreaticoduodenal (PD) arterial arcades. Arteries of human abdominal organ complexes (50) were injected with resin mixture, and then corroded. CT scans and three-dimensional reconstructions were made; diameters of arcades were measured. Two PD arcades were found in 58%, three arcades in 30%, one arcade in three cases, four arcade in one specimen, and five arcades in two cases. In the casts with two arches the average diameter was 1.472 ± 0.432 mm on the anterior and 1.383 ± 0.343 mm on the posterior arch. Assessing the dominance of the PD arcades, the anterior arch proved to be dominant in 52% of the cases, and in 35% the posterior one by the criterion of 25% cross-section difference. It is advised to analyze the variations and dominance on a CT/MR-angiography before local chemotherapy. Furthermore, to reveal the arterial variations, a preoperative CT/MR-angiography would provide faster recuperation and better postoperative life quality.
