Reverse Cascade Filtration of Ascitic Fluid-Preliminary Results

Refractory ascites is an infrequent complication of cirrhosis. Paracentesis and ultrafiltration of the ascitic fluid with intravenous or intraperitoneal reinfusion of the concentrated ascites has been used as therapy for this condition since 1971. The technique is cumbersome and has high morbidity and mortality rates, even if effective. In this paper we describe a new technique that couples secondary filtration for the removal of macromolecules, with ultrafiltration of ascitic fluid. In its very first application 6 patients underwent 8 treatments. No adverse effect was observed and clinical efficacy was good. Up to 60 g of albumin can be saved in a single session lasting less than 2 hours.
