  Executive Summary Portal vein gas (PVG) is a critical radiological sign indicative of serious underlying intra-abdominal pathology , most notably bowel ischemia and mesenteric vascular accidents . While historically associated with a mortality rate reaching 75% , advancements in diagnostic imaging—specifically Computed Tomography (CT)—have identified an increasing number of cases related to benign conditions that can be managed conservatively. Bowel ischemia remains the most prevalent cause, accounting for approximately 61.44% of reported cases . The diagnosis of the underlying etiology relies on the correlation of clinical signs with radiological findings. Management strategies are categorized by patient stability and the presence of acute abdominal features : immediate surgical intervention is mandated for patients with acute abdominal signs, while stable patients without mesenteric ischemia may be candidates for conservative treatment . Ultimately, prognosis is determined...

  Executive Summary Hepatic portal venous gas (HPVG) is a critical radiological sign characterized by abnormal gas accumulation in the portal vein and its intrahepatic branches . Historically associated with a 75% mortality rate and regarded as a mandatory indication for surgery , HPVG management has evolved significantly due to advancements in computed tomography (CT). Recent data indicates that HPVG is a marker of serious underlying disease but does not universally require surgical intervention . In a retrospective study of 21 patients, the overall in-hospital mortality rate was 23.8% , with bowel necrosis identified as the primary driver of fatal outcomes . While surgical and conservative treatments showed similar survival rates (approximately 75–77%), the decision to operate is increasingly guided by specific clinical predictors . Key indicators for surgical necessity include low platelet counts, elevated neutrophil levels , and the presence of hypertension or peritonitis ....
