[Portal venous stent placement for variceal hemorrhage in the elevated jejunum caused by portal vein stenosis after pancreatoduodenectomy:a case report].

An 86-year-old male underwent pancreatoduodenectomy with resection and reconstruction of portal vein for pancreatic cancer. He was admitted to our hospital because of severe anemia and dyspnea ten months later. Computed tomography showed varices at the biliary-enteric anastomosis in the elevated jejunum caused by portal venous stenosis, which was suspected as the cause of anemia. Therefore, the patient underwent balloon dilatation of the portal vein followed by stent placement and coil embolization of the collaterals using a transileocolic portal vein approach. After the procedure, portal venous flow was improved, and the collaterals disappeared. The patient has been asymptomatic with no recurrence for three years and four months.
