Double filtration plasmapheresis.

Guest Editor's Introduction: This paper was presented at the 26th ASAIO Congress held in April 1980. It was printed in Trans. Am. Soc. Artif. Intern Organs, Volume 26, page 406–411, 1980, and reprinted here with permission. This is the first clinical paper dealing with double filtration plasmapheresis. The plasma separator was made using Kuraray's polyvinyl alcohol hollow fiber, and Kuraray's plasma fractionator was made of ethylene vinyl alcohol hollow fibers. Seven patients afflicted with various diseases were treated by this method for 2 to 10 sessions. This procedure required supplemental infusion of albumin solution.
