OBJECTIVETo analyze the clinical characteristics diagnosis and treatment of patients with mesenteric venous thrombosis early after operation.

METHODSA retrospective study was performed on the clinical data of 7 patients with mesenteric venous thrombosis early after operation from 1990 to 2004.

RESULTSPatients had main clinical manifestations of severe abdominal pain and vomiting, but abdominal signs were slight. The systemic toxic symptoms occurred in 2 cases at late course. The examination of abdominal X- ray showed intestinal obstruction of all patients. Four patients received abdominal CT- scanning, of whom 3 patients were diagnosed as mesenteric venous thrombosis. Seven patients received exploratory operation. The necrotic intestinal segments were resected. Two patients had short intestinal syndromes after operation, one of them died of serious malnutrition. Four patients who had recurrence of portal, mesenteric and iliac venous thrombosis needed a long-term therapy of warfarin and aspirin after discharge.

CONCLUSIONIt is easy to make a mistake in diagnosis because of the lacking of characteristic clinical manifestations. Exploratory operation immediately plus anticoagulant therapy is strongly recommended.

Portal and mesenteric venous thrombosis is an uncommon disease, but clinically important, because it accounts for 5% to 15% of acute mesenteric ischemia. The diagnosis is often delayed because the conditions are nonspecific abdominal symptoms. In addition, when this occurs in young individual without any known predisposing factor, the diagnosis may become even more difficult. The treatment of mesenteric venous thrombosis involves anticoagulation therapy alone or in combination with surgery. The addition of thrombolytic therapy to the treatment of portal and mesenteric venous thrombosis may enhance the clearance of thrombus and hasten the clinical improvements. We present a case of mesenteric venous thrombosis treated with catheter-directed infusion of urokinase via the superior mesenteric artery and systemic anticoagulation.

AIMTo study preventive and therapeutic effect of zinc sulfate on lung injury during superior mesenteric artery occlusion (SMAO) shock and their mechanism of action.

METHODSModel of rabbit SMAO shock was made. The effect of zinc sulfate on the malondialdehyde (MDA) in erythrocyte membrane and plasma, oxidase (XOD) in plasma, superoxide dismutase (SOD) in erythrocyte and MDA, SOD and pulmonary surfactant (PS) in lung tissues homogenate were observed.

RESULTSThe administration of zinc sulfate decreased MDA and XOD, prevented the reduction of SOD and PS, and alleviated lung injury.

CONCLUSIONIt is suggested that lung is injured during SMAO shock and zinc sulfate possesses preventive and therapeutic effect, through stabilized membrane.
