摘　　要：目的　分析急性肠系膜上静脉血栓形成的临床特点及CT表现 ,提高认识水平。方法回顾性分析 6例经手术证实为肠系膜上静脉血栓形成的CT表现。平扫 6例 ,增强扫描 2例。结果6例CT平扫均出现腹腔积液、肠壁增厚、肠腔变窄、肠系膜密度增高模糊、肠系膜上静脉内高密度阴影等征象。 4例可见肠系膜上静脉增宽 ,3例可见肠系膜间游离积液 ,2例增强扫描可见肠系膜上静脉内低密度血栓影 ,静脉壁环形强化呈“靶征”。结论　CT检查对于早期诊断肠系膜上静脉血栓形成是一种有价值的方法。对于不明原因所致腹痛应及时行CT检查。Objective To analyze the clinical feature and CT findings of acute mesenteric venous thrombosis (AMVT) and improve the understanding of AMVT Methods CT findings of 6 AMVT cases proved by operasion were reviewed Abdominal non contrast CT scan was performed in 6 cases and contrast enhanced CT scan in 2 cases Results CT imaging of the 6 cases showed free peritoneal fliud, thickened bowed wall, narrowed bowle loop, raised and blurred mensenteric density or high density, and high density in the superior mesenteric veins The mesenteric veins were widened in 4 cases, and free fluid between mensenterium was detected in 3 cases Contrast enhanced CT scan in 2 cases revealed low density mesenteric venous thrombus shadow, and the venous wall was enhanced as circular pattern, presenting the “target”sign Conclusion CT scan is a valuable method in the early diagnosis of AMVT For patients with acute cryptogenil abdominalgia, CT scan should be immediately performed
