a) Digital subtraction angiography demonstrating anatomical classification Type B1. The gastroduodenal artery (GDA) arises off the proximal portion of the common hepatic artery (CHA). Gastric arterial branches originate from the proper hepatic arterial (PHA) segment distal to the origin of the GDA. The right hepatic artery (RHA) and the medial branch of the left hepatic artery (LHA-med) originate at acute angles when compared with the lateral branch of the left hepatic artery (LHA-lat). b) Digital subtraction angiography demonstrating anatomical classification Type B2. The common hepatic artery (CHA) cannot be clearly delineated as a separate segment. The celiac axis trifurcates into the splenic/gastric arterial branches, the CHA and the gastroduodenal artery (GDA). Gastric arterial branches may originate from the proper hepatic arterial (PHA) segment distal to the origin of the GDA. The right hepatic artery (RHA) and the medial branch of the left hepatic artery (LHA-med) originate at acute angles when compared with the lateral branch of the left hepatic artery (LHA-lat).
