[Clinical analysis of 7 cases of mesenteric venous thrombosis]

7 patients with mesenteric venous thrombosis (MVT) were treated in Anzhen Hospital from 1984 to 1996. The patients were all operated on and the diagnosis was confirmed pathologically. Fine patients were cured and 2 died. We discussed the pathophsiology, pathogeny, clinical manifestation, diagnosis and treatment of MVT. Most of the patients presented with a clinical picture of acute abdomen and the diagnosis was made only at laparotomy. Close observation and proper laparotomy should be given to the doubtful cases. To reduce the mortality rate of MVT, we resected the bowel which looks normal in appearance but comprises the mesentery of thrombosis. Adequate anticoagulant therapy should be given as early as possible.
