The diagnosis of bowel infarction is still a challenge. In some cases, portal venous gas is an associated feature and in these patients, the prognosis is very poor. We report on our experience with two consecutive cases in which ultrasonography showed gas in the portal venous branches, and also in the hepatic veins in one of them. ⋯ Other cases of portal venous gas associated with bowel infarction have been reported, but this is the first report of gas also being found in the hepatic veins. There may be a relationship between the amount of gas in the intrahepatic veins and the stage of bowel ischemia. Confirmation of this might improve the selection of patients and eliminate unnecessary procedures.

We reviewed all trauma deaths occurring in the urban area of Milan during one year. Autopsy reports were cross-referenced with pre- and in-hospital records and the Injury Severity Score was calculated by a senior surgeon. Causes of deaths were defined as central nervous system injury (CNS), hemorrhage (HEM), combined central nervous system injury and hemorrhage (CNS + HEM), and burns (BURN). ⋯ The Injury Severity Score decreased from DOS to in-hospital deaths (p < 0.05). The preventability rate was higher for in-hospital deaths (p < 0.05). The results of this study suggest that the development of a tiered trauma system in Milan is mandatory.
