Advancement in the diagnosis and treatment of hepatic portal venous gas

Figure 1  The comparison of mortality rates across etiologies.

Figure 2 Contrast-enhanced abdominal computed tomography. A: Hepatic portal venous gas (HPVG) is localized in the left lobe of the liver, and closer to the liver capsule (the arrow shows the gas); B: HPVG exhibits the classic “withered branches” expansion (the arrow shows the gas); C: HPVG involves the superior mesenteric vein and portal vein (the arrow shows the gas); D and E: Pneumobilia is typically centrally located within the liver (the arrow shows the gas); F: The rare presence of gas shadows closing to the liver capsule in the Pneumobilia (the arrow shows the gas).
