title: [Obstruction of the Le Veen shunt: a new surgical solution].
abstract: The authors propose an alternative which has been proved valid in four cases of peritoneovenous shunt with an occluded Le Veen valve for venous thrombosis implanted in cirrhotic patients with refractory ascites. After having explored the various possibilities using the vessels adjacent to the superior cava branch, the authors resolved the problem of reimplanting the valve by using an access route through the saphenous vein and inferior vena cava. Using this technique it was possible to reactivate the shunt with a marked improvement in the recurrent ascitic state and above all shunt functionality, and consequently in the clinical conditions and quality of life of these patients.
