Figure 3 Schematic illustration of preoperative surgical planning. A schematic drawing generated from a careful review of the original computed tomography dataset, illustrating the anomalous portal vein, hypoplastic pancreas, surgically relevant collateral vessels, and the planned extent of resection. Orange lines indicate the planned transection lines, and orange arrows indicate the planned division of the median arcuate ligament. CA: Celiac artery; LGA: Left gastric artery; MAL: Median arcuate ligament; RGEA: Right gastroepiploic artery; SA: Splenic artery; SV: Splenic vein; RGEV: Right gastroepiploic vein; SMA: Superior mesenteric artery; CBD: Common bile duct; ASPDA: Anterior superior pancreaticoduodenal artery.
