Transhepatic preoperative portal vein embolization using the Amplatzer Vascular Plug: report of four cases.
The Amplatzer Vascular Plug (AVP) is a device originally intended for arterial and venous embolization in peripheral vessels. From December 2004 to March 2007 we implanted a total of 8 AVPs in the portal venous system in our institution for preoperative portal vein embolization in 4 patients (55-71 years) prior to right hemihepatectomy. AVP implantation was successful in all patients. Total occlusion of the embolized portal vein branches was achieved in all patients. There were no major complications associated with the embolization.
