esophagogastric varices are a frequent complication of portal hypertension. bleeding from ectopic varices of the ileum is not only life-threatening, but its accurate diagnosis is also difficult. we have presented the case of a 31-year-old man with massive hematochezia. he was a known case of non-cirrhotic portal hypertension since 15 years prior. conventional examination that included angiograp...
abstractbackground: although electronic portal imaging devices (epids) have originally developed for positioning verification, they can also be used for dosimetric purposes. in the current work, the dose response of minimum detectable thickness of a scanning liquid filled ion chamber epid, slic-epid, and the variation of transmitted dose with the shift of inhomogeneity inside of phantom was als...
we report a case of a 40 year old man with portal hypertension caused by a splenic arteriovenous fistula that was diagnosed at laparotomy. he presented with bleeding esophageal varices and was initially treated by sclerotherapy. at laparotomy, portal pressure was 40 cmh20 but fell to 20 cm h20 after the fistula was treated with splenectomy. all symptoms disappeared shortly after operation and t...
