The thrombogenic effect of haemodialysis assessed by its influence on clot retraction,platelet volume,and platelet number

Regular haemodialysis in eight patients using hollow fiber dialysers had no significant effect on clot retraction, platelet volume or platelet number. The observed low or subnormal values of platelet number, platelet volume and clot retraction in the whole group would seem to be a secondary, long-term effect of dialysis.
