Abstract
Segmental edema is treated by inserting a plasma extraction filter device in a major vein of a body segment or servicing the body segment containing the edemic tissues, and inserting a return catheter in a major artery of the body segment affected or feeding the body segment from which plasma is extracted. Blood plasma and plasma proteins extracted from the edemic body segment through the plasma extraction filter fluids are directed to an ultrafiltration apparatus where plasma water is separated from the plasma proteins. Plasma proteins are returned to the body segment from which the plasma was extracted via the return catheter in the major artery of the subject body segment.
