Abstract
A 74-year-old man with chronic renal failure was admitted to the renal unit with non-specific symptoms and positive blood cultures. He later deteriorated and was admitted to the Intensive Care Unit with septic shock, respiratory failure and deranged liver function. Initial improvement was followed by abdominal distension and discomfort. Portal venous gas (PVG) and thrombosis were diagnosed on computed tomography. A conservative line of management was adopted. Improvement was soon followed by deterioration with septic shock. Extensive portal venous gas and free intra-abdominal gas were now evident on repeat computed tomography. The patient was too unwell to withstand surgery and a decision was made not to escalate therapy. He died on day 16. Portal venous gas is not a disease; it is a diagnostic clue in patients who may be harbouring an intra-abdominal catastrophe. Successful management of these cases requires early identification of the underlying pathology and can range from simple observation to extensive surgical intervention.
