背景/目的：儿童肝外门静脉高压的原因尚未明确。我们的目的是通过三维计算机断层扫描门静脉造影确定肝外门静脉高压症儿童肝外门静脉的形态特征，并阐明该疾病的病因。 材料与方法：6例年龄10至18岁（中位年龄12.8岁）的门静脉高压症患者，表现为呕血。他们使用螺旋计算机断层扫描仪和 3 维图像重建进行了静脉计算机断层门静脉造影。结果：通过 3 维计算机断层扫描门静脉造影，所有患者的肝外门静脉均可见。没有患者出现肝外门静脉阻塞或海绵样变性。所有患者的肝外门静脉均呈迂曲的eta形，可从门静脉的弯曲处划一条线至肝门。结论：儿童肝外门静脉高压并非由肝外门静脉阻塞引起，可能是胚胎学原因。 (c) 2006 Elsevier Inc. 保留所有权利。
Background/Purpose: The cause of extrahepatic portal hypertension in children has not been clarified. Our aim was to determine the morphological features of the extrahepatic portal vein in children with extrahepatic portal hypertension by 3-dimensional computed tomographic portography and to clarify the etiology of this disorder.Materials and Methods: Six patients ranging in age from 10 to 18 years (median age, 12.8 years) who had portal hypertension presented with hematemesis. They underwent intravenous computed tomographic portography using a helical computed tomography scanner and 3-dimensional image reconstruction.Results: The extrahepatic portal vein was visualized in all patients by 3-dimensional Computed tomographic portography. None of the patients showed extrahepatic portal vein obstruction or cavernous transformation. All patients had a tortuous eta-shaped extrahepatic portal vein, and a line Could be drawn through the flexures of the portal vein to the hepatic hilum.Conclusion: In children, extrahepatic portal hypertension is not caused by extrahepatic portal vein obstruction and may be of embryological origin.
