摘　　要：目的:分析急性门静脉及肠系膜上静脉血栓形成的临床及CT表现。方法:回顾性分析9例经手术及临床综合诊断证实的急性门静脉及肠系膜上静脉血栓形成病例的CT表现,9例均行CT平扫,3例行增强扫描。结果:9例CT平扫均显示门静脉或肠系膜上静脉增粗,7例见腔内高密度影,8例见腹腔积液,5例见小肠管壁增厚、水肿;3例强化扫描示静脉内低密度充盈缺损。结论:CT对诊断急性门静脉及肠系膜上静脉血栓形成具有重要意义;临床上对急性腹痛,不明原因腹水及可疑肠梗阻的病例,应注意观察其门脉系统情况。Objective：To explore the clinical feature and CT findings of acute portal and superior mesenteric venous thrombosis. Methods：CT findings of 9 cases of surgically and clinically proved acute portal and superior mesenteric thrombosis were studied. Plain CT scans were performed in all cases; contrast enhanced CT scans were performed in 3 cases. Results：In plain CT scan images, 9 cases showed dilatation of the vein, 7 cases showed high density lesions in the lumen, 8 cases showed free peritoneal fluid and 5 cases showed small bowel wall thickening and edema. In 3 contrast-enhanced cases, low density filling defect clue to thrombosis was revealed. Conclusion： CT examination is a valuable method in detecting acute portal and superior mesenteric venous thrombosis.
