Portal venous gas and thrombosis complicating superior mesenteric artery syndrome (Wilkie's syndrome) in a child.

We report a case of a 10-year-old girl presenting with portal venous gas and thrombosis associated with superior mesenteric artery syndrome. To our knowledge, this is the first reported case of superior mesenteric artery syndrome complicated by gastric wall pneumatosis, portal venous gas, and thrombosis in childhood. Although these complications usually lead to bowel resection in adults and result in a high mortality rate, our pediatric patient was successfully treated nonoperatively with intensive care management and jejunal tube feedings. Presence of portal venous gas may occur in superior mesenteric artery syndrome in children and does not necessarily lead to bowel injury, allowing conservative medical management as a first-line treatment.
