Portosystemic shunt is most frequent in portal hypertension associated with hepatic cirrhosis, meanwhile there are uncommon cases which have congenital portosystemic shunt. Recently we have encountered a patient with ductus venosus definitely diagnosed by angiography. In this patient, we performed a portal scintigraphy with 123I-IMP per-rectal administration in order to evaluate the portosystemic circulation. At the early phase of the study, the scintigraphy showed only the pulmonary uptake of 123I-IMP, and the liver was not revealed. Such findings in congenital anomalous cases of portosystemic shunt without hepatic parenchymal damage like this case can be similar to those in cirrhotic patients. In conclusion, this method was useful in evaluation of the portosystemic circulation, and helpful in determining therapeutic procedures for portosystemic circulation disorders.
门体分流在与肝硬化相关的门静脉高压症中最为常见，同时也有先天性门体分流的罕见病例。最近我们遇到了一名经血管造影明确诊断为静脉导管未闭的患者。在该患者中，我们经直肠给予123I-IMP进行门静脉闪烁扫描，以评估门体循环。在研究的早期阶段，闪烁扫描仅显示123I-IMP在肺部的摄取，肝脏未显影。像这种没有肝实质损害的先天性门体分流异常病例的表现可能与肝硬化患者相似。总之，该方法有助于评估门体循环，并有助于确定门体循环障碍的治疗方案。
