Abstract
We report a case of portal vein stenosis due to pancreatic cancer that was successfully treated with intravenous stent implantation. The patient was a 49-year-old woman who had undergone a pancreatoduodenectomy with the modified Child's method for pancreatic carcinoma and was re-admitted due to melena and severe anemia 20 months after the operation. CT findings revealed that recurrence of pancreatic cancer had narrowed the portal vein and had caused hepatopetal collaterals adjacent to the choledochojejunostomy. Additionally, gastrointestinal endoscopy revealed an exposed vessel at the mucosa of the jejunum, close to the choledochojejunostomy. Bleeding from the varices increased and a hepatopetal collateral was considered to be the cause of the melena ; therefore, an intravenous stent was surgically placed at the site of stenosis of the portal vein. Subsequently performed portography revealed that the collaterals disappeared after the stent replacement and that no further episodes of gastrointestinal hemorrhage had occurred.
