Figure 3 Summary diagram of common vascular variations related to gastric cancer surgery. A: Normal type, the common hepatic artery originated from the celiac artery trunk, giving off the proper hepatic artery and the gastroduodenal artery, which continues to divide into the right gastric artery and the right and left hepatic arteries[11]; B: Variant origin of the left hepatic artery from the left gastric artery; C: Right hepatic artery originating from the superior mesenteric artery; D: Left hepatic artery variant originating from the left gastric artery and the right hepatic artery originating from the superior mesenteric artery[12,13]; E: Left parahepatic artery originating from the left gastric artery[12-17]; F: Right parahepatic artery originating from the superior mesenteric artery; G: Left parahepatic artery originating from the left gastric artery and right parahepatic artery originating from the superior mesenteric artery; H: Right hepatic artery originating from the superior mesenteric artery and left parahepatic artery originating from the left gastric artery; I: Common hepatic artery originating from the superior mesenteric artery; J: Common hepatic artery originating from the left gastric artery[12-15]; K: Left hepatic artery variant originating from the left gastric artery but no other hepatic arterial branches around. CHA: Common hepatic artery; CA: Celiac artery; PHA: Proper hepatic artery; GDA: Gastroduodenal artery; RGA: Right gastric artery; LHA: Left hepatic arteries; SA: Splenic artery.
