Abstract: Erythrocyte aggregation was measured in 12 patients with congenital dysfibrinogenemia. The results showed hyperaggregation in four patients who had presented a thrombotic disorder, while aggregation was entirely normal in patients with asymptomatic dysfibrinogenemia. None of the four symptomatic patients had any other anomaly of hemostasis, in particular no coagulation inhibitor deficit or anti‐phospholipid antibodies. The possible involvement of erythrocyte hyperaggregation in the thrombotic process is discussed.
