Plasmapheresis in hyperviscosity syndrome
Three patients with Waldenström's macroglobulinaemia developed circulatory complications due to increased plasma viscosity, i.e. relative viscosity value above 4. Plasmapheresis was performed either in a Haemonetics 30 S cell separator, by plasma filtration through a CPS 10 TM filter or by a double-double pack Fenwal system. All three methods reduced the plasma viscosity and abolished the clinical symptoms. In cases of acute hyperviscosity syndrome, apheresis of small amounts of plasma by the double-double pack system may serve as an alternative to the more advanced techniques.
