Preoperative embolization of the right portal vein and following hepatic resection were performed in seven patients with primary and secondary liver malignancies. The indication for the procedure was a small amount (30%) of the future remnant liver (FRL). The ultrasound-guided percutaneous transhepatic puncture of the portal vein and its embolization with gelatin sponge or silicon polymer was used. No complications of the procedure were noted. In 19-56 (mean 33) days computed or magnetic resonance tomography showed a significantly increased FRL volume (mean 40%). Right or extended right hepatectomy was performed in 5 and 2 patients respectively without lethal outcomes. A conclusion is made that the preoperative portal vein embolization is a safe and technically simple procedure that reduces the risk of postoperative hepatic failure after major liver resection.
