CT平扫在急性肠系膜上静脉血栓形成诊断中的价值

Nonenhanced CT Diagnosis of Acute Superior Mesenteric Venous Thrombosis

目的:分析急性肠系膜上静脉血栓形成的平扫CT表现及其价值。方法:回顾性分析6例经手术证实为急性肠系膜上静脉血栓形成的平扫CT表现。结果:6例CT平扫均出现肠壁增厚、肠系膜脂肪密度增高模糊、肠系膜上静脉增宽,其内出现高密度阴影等征象。1例可见腹水。结论:CT平扫对于诊断急性肠系膜上静脉血栓形成是一种有价值的方法。

Objective To analyze the findings and value of nonenhanced CT of acute superior mesenteric venous thrombosis.Methods Findings of nonenhanced CT scans of 6 cases of acute superior mesenteric venous thrombosis proved by operation were reviewed.Results CT imaging showed thickened bowed wall,high attenuation and engorgement of mesenteric veins,and mesenteric stranding in all the 6 cases and free peritoneal fluid in 1 case.Conclusion Nonenhanced CT scan is a valuable method in the early diagnosis of acute superior mesenteric venous thrombosis.
