华支睾吸虫病影像诊断的实验研究

目的探讨作者华支睾吸虫致胆道阻塞的影像表现及诊断价值。方法对经实验性感染华支睾吸虫的犬,依感染数量和观察时间的不同,分别进行实验病理、B超、CT的同步观察。结果华支睾吸虫感染后第5~15日,即见肝内少数胆管壁增厚,继而肝内胆管广泛轻度扩张,实验犬肝内病变程度同感染虫体数量及感染时间长短有明显的相关性;本组实验犬B超、CT检查所见肝内胆管阻塞扩张,病变分布特点以及胆管树比例失调与大体解剖所见一致的。结论超声所见同病原学检查具有同等重要的诊断价值,在华支睾吸虫感染初期B超、CT检查所见改变具有早期诊断价值。

Experimental study on image diagnosis of clonorchiasis sinensis.

Objective To investigate the image characteristics and its diagnostic value for obstructive jaundice caused by Clonorchis sinensis.Methods Synchronous observations of pathology, B-ultrasound, and CT were made on dogs infected with different number of larvae of C. sinensis at different time point postinfection.Results walls of several intrahepatic bile duct were thicker 5-15 days postinfection. Then most bile ducts were slightly dilated. It is found that the degree of pathological changes of the liver is related to the number of larvae infected and the length of infection. In addition, the dilation of intrahepatic bile duct, the distribution characteristics of pathological changes, and imbalanced proportion of the bile duct tree revealed by ultrasound and CT scanning are consistent with the findings in pathological examination.Conclusion B-Ultrasound and CT are of value to the early diagnosis of clonorchiasis.
