Bleeding esophageal varices associated with pancreatic arteriovenous malformation.
Three cases of bleeding esophageal varices associated with arteriovenous malformation of the pancreas have been observed over the last 7 years. In 1 case, arteriovenous malformation (AVM) was the cause of the portal hypertension; thus, it was considered to be a "primary lesion." In the other cases, liver cirrhosis was the cause of the portal hypertension, and the AVM, which originally was a minor pathology, became significant as the portal hypertension progressed, thus making it a "secondary lesion." In the case of a "primary lesion," resection of the lesion is the preferred treatment for bleeding varices, but our case had multiple lesions, and excision was problematic. In the case of bleeding varices caused by liver cirrhosis, if liver function is normal, surgical treatment of both the varices and the AVM is recommended, while if the liver function is abnormal, repeated sclerotherapy is the best mode of therapy.
