Preoperative blood circulation modification prior to pancreaticoduodenectomy in patients with celiac trunk occlusion: Two case reports

Figure 2 Computed tomography with 3D reconstruction of the vascular anatomy in case 1. Computed tomography showed a right hepatic artery (RHA) and middle hepatic artery originating from the common hepatic artery, the usual pancreaticoduodenal arcade originating from the gastroduodenal artery, a common trunk between the dorsal pancreatic artery and pancreaticoduodenal artery originating from the superior mesenteric artery, an additional arcade originating from the common trunk and passing through the dorsal surface of the pancreatic head and linking directly to the RHA, and a replaced left hepatic artery originating from the left gastric artery. RHA: Right hepatic artery; MHA: Middle hepatic artery; CHA: Common hepatic artery; PDA: Pancreaticoduodenal artery; SMA: Superior mesenteric artery.
