Portal venous gas has historically been associated with a poor prognosis. The clinical outcomes of 17 patients with portal venous gas detected by CT were reviewed.
Portal venous gas seen on CT was associated with a 71% survival rate. Patients with a history of vascular surgery or bowel obstruction may have a higher mortality, and careful clinical evaluation is mandatory in this patient population.
