    Hepatic portal venous gas (HPVG) is a rare radiologic finding linked to various intra-abdominal and systemic diseases.

  • 2

    In a study of 16 patients, major causes of HPVG included intra-abdominal infection, gastrointestinal bleeding, and intestinal obstruction.

  • 3

    Conservative management of HPVG resulted in a 62.5% in-hospital mortality rate, with lower serum albumin and higher procalcitonin levels in non-survivors.

  • 4

    Imaging follow-up showed complete gas resolution in several patients after addressing underlying conditions, indicating HPVG is a radiologic manifestation.

  • 5

    The study suggests that combining imaging dynamics with biomarkers can improve early risk stratification and guide management of HPVG.
