A Case of Portal Venous Gas Secondary to Acute Appendicitis Detected on Gray Scale Sonography but Not Computed Tomography

A case of portal venous gas secondary to acute appendicitis detected on gray scale sonography but not computed tomography.

A case of portomesenteric venous gas detected on computed tomography.

Portomesenteric vein gas is a rare condition, which pathogenesis is not completly understood. One of causes is e.g. mesenteric ischemia. Pathogenesis of this condition are: intraabdominal sepsis, interventional procedures, liver transplantation, Crohn disease and trauma. In 15% of causes its idiopathic. Hepatic portal venous gas predict high risk of mortality (>50%). An advanced radiology techn...

Portal venous gas detected by computed tomography: is surgery imperative?

BACKGROUND Portal vein gas (PVG) has historically been associated with mortality rates of 75% or higher and mandatory abdominal exploration. The following study reassesses the clinical significance of gas in the portal venous system detected by computed tomography (CT) and reevaluates the need for surgical intervention in that setting. METHODS We performed a retrospective chart review of 26 p...

Rare Association of Hepatic Portal Venous Gas in Acute Appendicitis: a case report

Hepatic portal venous gas (HPVG) is usually associated with acute fatal abdominal disease. It has not previously been reported to be associated with acute appendicitis. We reported a case of acute appendicitis associated with HPVG in a middle-aged man who recovered uneventfully after appendectomy. We described the CT findings and emphasized that an HPVG resulting from appendicitis may not as om...

[Portal pneumatosis secondary to acute appendicitis].

Portal vein pneumatosis is a radiological finding that is classically associated with intestinal necrosis and ischemia, but it has also been described associated with other abdominal pathologies. What is interesting about the case that we report is the unusual presence of this entity in a commonly treated disease in the emergency surgery department. The patient is a 59-year-old male who came to...
