Although the patent ductus venosus is congenital, the symptoms due to hyperammonemia vary, possibly depending on the shunt ratio and individual tolerance to ammonia. We have experienced two adult patients with large caliber patent ductus venosus and compensated liver cirrhosis. In one case, the ductus venosus simply communicated to the portal vein, but in the other case there were multiple short communicating vessels between the ductus venosus and left portal vein. Both cases were successfully treated by the transvenous embolization with steel coils and ethanolamine oleate, which has an expansive nature.
