Background:
Hepatic portal venous gas, which may occur in conjunction with severe intra-abdominal infections, is associated with a high mortality rate and is considered as an alarm signal.
History:
CT diagnostics revealed hepatic portal venous gas in a 65-year-old patient with advanced perforated sigmoid diverticulitis. This phenomenon was also observed in a 75-year-old patient in association with an upside-down stomach incarceration. Both patients underwent emergency surgery and survived this life-threatening disease.
Conclusion:
Since hepatic portal gas is usually caused by severe intra-abdominal diseases with a high mortality rate, this warning sign should, at the latest, result in urgent laparotomy, if the indication has not already been established for other reasons.
Insights
Hepatic portal venous gas (HPVG) is a critical indicator of severe intra-abdominal conditions. Prompt surgical intervention is crucial for survival in patients presenting with HPVG.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Emergency
Background:
- Hepatic portal venous gas (HPVG) is a rare radiological finding.
- HPVG is often associated with severe intra-abdominal infections and carries a high mortality rate.
- It serves as a critical alarm signal for potentially life-threatening conditions.
Observation:
- CT scans identified HPVG in two patients.
- Case 1: A 65-year-old with perforated sigmoid diverticulitis.
- Case 2: A 75-year-old with incarcerated upside-down stomach.
Findings:
- Both patients with HPVG underwent emergency surgery.
- Successful surgical outcomes were achieved in both cases.
- This highlights the treatable nature of HPVG under prompt surgical management.
Implications:
- HPVG necessitates urgent clinical evaluation and consideration for immediate laparotomy.
- Early surgical intervention is vital for improving patient outcomes in HPVG cases.
- Radiological detection of HPVG should trigger rapid multidisciplinary assessment and management.
