[Hepatic portal venous gas. Clinical significance and review of the literature]. / Gas venoso portal intrahepático. Significado clínico y revisión de la bibliografía.

Hepatic portal venous gas in adults is a rare entity. The most frequent cause is intestinal ischemia. However, an increasing number of cases associated with benign conditions suitable for conservative treatment are being reported. We review the literature to define the clinical significance of portal venous gas, the role of computed tomography, and the need to perform emergency exploratory laparotomy.
