Transhepatic portal venous angioplasty with stenting for bleeding jejunal varices.
A 54-year-old woman, who had undergone pancreatoduodenectomy with resection of the portal vein and intraoperative radiation therapy for cancer of the lower bile duct 16 months before, visited our institution complaining of melena. To identify the cause of bleeding and severe anemia, we performed gastrointestinal endoscopy but could detect no obvious source. The portal phase of the superior mesenteric arteriography and percutaneous transhepatic portography revealed severe stenosis of the extrahepatic portal vein, which corresponded to the end-to-end anastomosis of the portal vein, and hepatofugal collaterals. Extravasations into the afferent loop of the jejunum were detected only with portography. These findings suggested that portal hypertension due to extrahepatic portal obstruction led to bleeding varices. Subsequent to percutaneous transhepatic portography, we dilated the stenosis of the extrahepatic portal vein using a balloon catheter and placed an expandable metallic stent there. Portography after the treatment revealed the disappearance of the hepatofugal flow to collaterals and extravasations, and the patient has had no further episodes of gastrointestinal bleeding since. In conclusion, for patients with bleeding varices due to extrahepatic portal obstruction, especially after abdominal surgery, percutaneous transhepatic angioplasty is considered to be the treatment of choice because of its efficiency and minimal invasiveness.
