hyperviscosity syndromemedical dictionary


A syndrome resulting from increased viscosity of the blood; an increase in serum proteins may be associated with bleeding from mucous membranes, retinopathy, and neurological symptoms, and is sometimes seen in Waldenstrom's macroglobulinaemia and in multiple myeloma; an increased viscosity secondary to polycythaemia may be associated with organ congestion and decreased capillary perfusion.
