We report a case of portal-systemic encephalopathy occurring secondary to a splenorenal shunt, 2?years after a pancreaticoduodenectomy for locally advanced duodenal carcinoma. A 55-year-old woman was brought to our hospital with a decreased level of consciousness. Laboratory testing revealed an elevated serum ammonia level (221?μg/dl) and normal liver function. Retrospective review of a series of contrast-enhanced computed tomography scans of the abdomen identified a splenorenal shunt, which had gradually enlarged over the past 2?years (Fig.?1). The decreased level of consciousness was thought to be due to portal-systemic encephalopathy secondary to the splenorenal shunt. We performed balloon-occluded retrograde transvenous obliteration to occlude the splenorenal shunt, following which her serum ammonia level returned to normal (28?μg/dl) and an alert level of consciousness was maintained.
