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 η -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.展开更多

Design: Interventional case report. Methods: A 3- year- old girl who failed a public visual- screening test was examined. Since then, she had been followed- up for her epiretinal membrane, which began to peel spontaneously in the left eye for 11 years until a macular hole was observed. She was treated by vitrectomy and membranectomy, and the membrane was histologically examined. Result: The macular hole was successfully closed, and her visual acuity improved. The membrane appeared to have a homogenous structure and contained no cells. Conclusions: The juvenile idiopathic epiretinal membrane sometimes peels spontaneously. However, long- term follow- up is needed because vitreous traction of the membrane by intraocular aging change may result in a macular hole.展开更多
