Figure 5 Retrograde flow from the superior mesenteric artery due to tumor involvement of the hepatic artery. A: Computed tomography scan showed a low-density mass in the pancreatic head with common hepatic artery involvement (arrow); B: Selective celiacography showed involvement of the hepatic artery from the origin of the celiac artery to the bifurcation of the left and right hepatic arteries, as well as involvement of the gastroduodenal artery. Additionally, an accessory right hepatic artery was seen originating from the gastroduodenal artery; C: Superior mesenteric angiography showed retrograde flow to the liver from the superior mesenteric artery via the pancreaticoduodenal arcade.
