Partial portal arterialization in complete en bloc resection of the hepatoduodenal ligament and left lobe of the liver for hepatic hilar cancer.

The complete resection of the hepatoduodenal ligament is associated with enormous surgical invasion, which frequently results in postoperative hepatic dysfunction secondary to interruption of the reconstructed artery. We administered partial portal arterialization by anastomosis of the gastroduodenal artery to the portal vein without reconstruction of the hepatic artery in the complete resection of the hepatoduodenal ligament with resection of the left lobe of the liver in a patient with hilar bile duct carcinoma. After division of the proper hepatic artery, the gastroduodenal artery was anastomosed in an end-to-side fashion to the trunk of the portal vein. After division of the portal vein, to prevent ischemia, a single catheter bypass was inserted into a branch of the mesenteric vein and the another side of the catheter was attached to the hepatic end, of the portal vein. The portal vein was reconstructed with the superficial femoral vein graft. The blood supply to the remaining liver was interrupted for only 15 min during which the proximal end of the superficial femoral graft was anastomosed to the hepatic end of the portal vein. Postoperative liver function has been stabilized and his postoperative course is uneventful without portal hypertension. One month postoperatively, angiography through the vessels nourishing the raised jejunum visualized intrahepatic arteries.
