The kinetics and distribution in vivo of autologous 111‐In‐labelled platelets were studied in 20 patients with chronic hepatic disease. The patients, 16 of whom were thrombocytopenic, exhibited a shortened platelet mean life time, a reduced platelet recovery and a normal platelet turnover, the latter 2 of which were positively correlated to the platelet count. Platelet in vivo recovery was negatively correlated to the spleen volume. In accordance with this, scintigraphic studies revealed that the spleen was the major organ of platelet sequestration and destruction, the role of the liver being almost negligible. Signs of platelet destruction in the bone marrow were also found. Our results indicate that splenic platelet pooling and accelerated platelet destruction, accompanied by inability of the bone marrow to compensate for the thrombocytopenia are the main causes of the thrombocytopenia accompanying chronic hepatic disease.
