血吸虫感染儿童肝脏超声显像特征及治疗后病变的逆转观察

Sonographic Feature of Liver and the Observation of Disorder Reversal after Treatment in Children Infected with Schistosomiasis

为探讨血吸虫感染儿童肝脏在抗血吸虫治疗后的变化。对 3 8例感染儿童于治疗前后采用彩色多普勒超声进行了追踪观察。发现 :118例 ( 4 7.4 % )患者的肝脏的回声转为均匀型 ,小网络结构消失 ;2肝脾大小明显缩小 ( P<0 .0 1) ;3门静脉、脾静脉、肠系膜上静脉内径缩小 ( P<0 .0 1) ,时间平均速度 ( TAV)均有增快 ( P<0 .0 1) ;4中肝静脉明显增宽 ( P<0 .0 1) ,肝静脉频谱主要表现为三相型 ( 76.3 % ) ,其次为波幅降低平坦型 ,低平波型消失。结果表明 :血吸虫感染儿童经抗血吸虫药物治疗后 ,肝脾大小可恢复正常 ,内部回声和血流动力学可出现逆转 ,提示早期治疗感染儿童 ,对其肝脏病变的恢复有重要意义。

To investigate the changes of liver after anti-Schistosomiasis treatment in children infected with schistosomiasis, 38 infected children were studied by color Doppler flow imaging before and after treatment. It was found that: (1) Liver echo was transformed to hemogenicity form and small network structure was obliterated in 18 cases (47.4 %); (2) Volume of liver and spleen were significantly minified (P<0 01); (3) Diameters of PV, SPV, SMV were signifiecantly decreased (P<0 01) and time average velocity (TAV) was increased (P<0 01); (4) Diamiter of MHV was significantly increased (P<0 01), the spectrum of HV showed mostly three-phased type (76 3 %),then wave amplitude-lowered and planus type, and hypoplanus type was obliterated. The results indicated that the anti-Schistosomiasis treatment could repair the volume of liver and spleen of children infected with Schistosomiasis and reverse interior echoes and hemodynamicity, suggesting early treatment was important in the recovery of liver disorder of children infected with schistosomiasis.
