目的探讨肝小静脉闭塞病诊断 的CT临床表现。方法 统计分析2008年5月 至2014年5月江苏省射阳县人民医院收治 的80例肝小静脉闭塞病患者的临床资料。 结果 80例患者中，平扫64例患者斑块状 不均匀密度降低，16例患者肝实质密度弥 漫性降低，分别占总数的80.0%、20.0%； 增强动脉期28例患者右肝呈斑片状增强改 变，16例患者有小斑片状强化出现在肝 脏，36例患者没有明显强化改变，分别占 总数的35.0%、20.0%、45.0%；门静脉期 16例患者肝静脉缺乏清晰的显示或没有显 示，4例患者有细线样改变出现在肝右静 脉，分别占总数的20.0%、5.0%；平衡期 和延迟期螺旋CT扫描延迟3-5min显示70例 患者全肝呈斑片状低密度改变至少1个肝 段，10例患者基本趋于均匀，分别占总数 的87.5%、12.5%。延迟>10min显示34例患 者仍有散在小斑片状低密度区，占总数的 42.5%。结论 肝小静脉闭塞病的CT增强扫 描检查具有较高的临床诊断价值。

Objective To evaluate CT clinical manifestations in the diagnosis of hepatic veno-occlusive disease. Methods The clinical data of 80 cases of hepatic veno-occlusive disease patients who were treated in Sheyang County People's Hospital from May 2008 to May 2014 were statistically analyzed. Results Among the 80 cases of patients, unenhanced 64 cases were with plaque uneven density decreases, 16 cases diffuse liver parenchyma lower, accounting for 80.0%, 20.0% of the total, respectively; 28 cases were enhanced hepatic arterial phase and patches reinforcement change, 16 cases small patchy enhancement occurs in the liver, 36 cases did not change significantly enhanced, 35.0%, 20.0%, 45.0% of the total, respectively; 16 cases were with portal vein hepatic vein or the lack of a clear display not shown, 4 cases had thin like changes appear in the right hepatic vein, 20.0%, 5.0% of the total, respectively; Delayed 3-5min 70 cases were equilibrium phase and delayed phase spiral CT scans in show whole liver patchy low density change at least one liver segment, 10 cases substantially more uniform, 87.5%, 12.5% of the total, respectively. Delay>10min display 34 cases were still scattered in small patchy low-density areas, 42.5% of the total. Conclusion Enhanced CT scan has high clinical diagnostic value in the diagnosis of hepatic veno-occlusive disease.
