Peritoneovenous shunt function 2-6 years after insertion for cirrhotic ascites.
To test the hypothesis that prolonged freedom from clinically detectable ascites after peritoneovenous shunt insertion is the result of continued drainage of ascitic fluid through the shunt, the authors studied shunt patency and function in 26 of the 27 survivors of 59 alcoholic cirrhotic patients operated upon 2-6 years previously for massive ascites resistant to medical therapy. Twenty-three patients were without clinically detectable ascites (minimal ascites--Group A), and three had large ascites (Group B). In 20 Group A patients the shunts were patent and functioning. The other three Group A patients had completely occluded shunts without demonstrable ascitic fluid flow. In one Group B patient with a daily fluid intake of 5-6 L, the shunt was partially obstructed but flow was rapid; in the other two, shunts were completely occluded. One subject in Group B with a completely obstructed shunt was resistant to medical treatment after 6 years of freedom from ascites, whereas the other two were controlled medically. In the three in Group A who had nonfunctioning shunts and required no diuretics, the severity of the ascites had decreased so that artificial drainage was no longer necessary. Thus, freedom from clinically significant ascites does not always indicate that the shunt continues to function.
