^(99m)Tc-EHIDA肝胆显像评估citrin缺陷致新生儿肝内胆汁淤积症肝脏摄取和排泄功能

Evaluation of the hepatic uptake and excretion function with ^(99m)Tc-EHIDA hepatobiliary scintigraphy in neonatal intrahepatic cholestasis caused by citrin deficiency

目的评价核素肝胆显像在评估citrin缺陷所致新生儿肝内胆汁淤积症(NICCD)患儿的肝脏摄取和排泄功能中的价值。方法应用单光子发射型计算机断层扫描仪(SPECT)对12例经SLC25A13基因诊断为NICCD的患儿进行核素肝胆动态显像,观察肝脏摄取和排泄功能,并与血生化检查结果进行比较分析。结果 12例NICCD患儿在初诊时均有肝脏摄取功能严重受损和排泄功能障碍,其中5例在治疗随访中进行了第2次核素肝胆动态显像,显示肝脏摄取和排泄功能基本正常。NICCD患儿的肝脏摄取和排泄功能与肝细胞病变和胆汁淤积程度一致。结论核素肝胆显像对NICCD患儿肝脏摄取和排泄功能的评估具有重要价值。

Objectives To investigate the value ofhepatobiliary scintigraphy in evaluation of the hepatic uptake and excre- tion function in neonatal intrahepatic cholestasis caused by citrin deficiency （NICCD）. Methods Hepatobiliary scintigraphy with SPECT was used to detect the hepatic uptake and excretion function of 12 patients with NICCD confirmed by SLC25A13 gene analysis, and the results were compared with the results of blood biochemical tests. Results The hepatic uptake and excretion function were obviously impaired in all of 12 NICCD patients in the initial scintigraphy. The scintigraphy were performed again in 5 patients in the follow-up after treatment, and showed that the hepatic uptake and excretion function was recovered. It was sug- gested that the hepatic uptake and excretion function was consistent with the level of liver enzymes and the degree of cholestasis. Conclusions Hepatobiliary scintigraphy is of value in evaluation of the hepatic uptake and excretion function in NICCD patients.
