摘要Portal vein stricture complicated with superior mesenteric venous thrombosis is rarely seen in clinical practice. On December 26, 2009, a 51-year-old male patient who had a liver transplantation history was admitted to The General Hospital of Chinese People's Armed Police Forces with the chief complaint of intermittent abdominal pain and diarrhea.A plain and enhanced CT scan showed that the portal vein was constrictive and thrombosis had formed in the main trunk of the superior mesenteric vein, and varicose veins were seen in surrounding tissues of the esophagus. Edema was observed at the end of the ileum and cecum. The results of colonoscopy showed inflammatory changes and varicose veins of the colon. The patient received medical treatment. The thrombosis was dissolved 9 days later, and all symptoms disappeared 12 days later.
