[123I-IMP per-rectal portal scintigraphy in a patent ductus venosus: a case report].
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.
