Interventional embolization with fibrin glue for a large inferior mesenteric-caval shunt.

We report an unusual case of a large inferior mesenteric-caval shunt in a 25-year-old man without cirrhosis with hypoproteinemia and hypochromic anemia. In this large shunt the direct communication was between the inferior mesenteric vein and the internal iliac vein. Hemodynamic change as a result of the shunt was thought to cause his present clinical problems and future portosystemic encephalopathy. Percutaneous transcatheter embolization of the shunt with fibrin glue was performed through the internal iliac vein, and this offered amelioration of hypoproteinemia and reduction of serum ammonia levels without any complications. An interventional radiologic approach instead of surgical ligation should be attempted for portosystemic shunts, and fibrin glue, as well as coils or a detachable balloon, is also valuable as an embolizing material.
