Selective percutaneous transhepatic embolization of the portal vein in preparation for extensive liver resection: the ipsilateral approach

The ipsilateral approach was used at preoperative portal vein embolization in 38 patients with hepatobiliary malignancy. The right anterior portal branch was punctured. Two different 5.5-F triple-lumen balloon catheters were used, and fibrin glue and iodized oil were injected. Portal vein embolization was successful in all cases (right lobe, 24 patients; left lobe and right anterior segment, six; right lobe and left medial segment, three; right posterior segment, two; right anterior segment, one; left lobe, one; and right and caudate lobes, one).
