Core Tip

Core Tip: Portal vein embolization (PVE) is relatively safe procedure done prior to major hepatic resection to enhance the future remnant liver. Intrahepatic portosystemic venous fistula is very rare in non-cirrhotic liver. Non-target embolization is a rare complication of such a procedure. This is the first case report of non-target lung embolization during PVE through a portosystemic venous fistula. Failure of recognition of this rare vascular abnormality led to this rare complication. In our case, we emphasize on careful evaluation of conventional portogram prior to PVE to avoid such complication.
