Failure of LeVeen shunting in refractory ascites--a view from the other side.
We have reviewed our experience with 11 patients treated with LeVeen peritoneovenous shunts during a 22-month period from March, 1976, through December, 1977, to assess long-term results and shunt patency. Nine patients had follow-up studies to assess shunt patency at a mean of 26 months. After insertion of the shunt, the mean weight loss was 7.9 kg at hospital discharge. At 26-month follow-up evaluation, six patients had minimal ascites (responders), whereas five had massive ascites (nonresponders). Of the six responders, three patients with nonfunctioning shunts lost an average of 15.8 kg of ascites, three whereas with patent shunts lost an average of 15.0 kg. Eight of 11 patients (73%) required revision or replacement of the shunt because of malfunction; clotting was the most common cause of failure. We conclude that the role and effectiveness of LeVeen peritoneovenous shunts remain questionable. They may cause diuresis, maintain it, or not be responsible for it all. Clinical reports that cite their effectiveness should document patency of these shunts.
