[High, asymptomatic and persistent thrombocytosis in splenectomized subjects].

The Authors illustrate clinicals evaluations of tree splenectomised patients, whose platelets' counts were normal in the pre-operatory period. The patients had shown, after splenectomy, high (platelets' count upper than 10(6)/mmc), asymptomatic (without hemorrhage and thromboembolism), persistent father four months, spontaneously and progressively decreasing thrombocytosis. Clinical evaluations and blood analysis concern respectively periods of four years and six months, two years and two months, three years and six months after splenectomy. Furthermore the Authors examine the splenectomy's role into thrombocytosis, and remark, on the contrary of inherent literature, that, in some occurrences, the splenectomy produces high, persistent and asymptomatic thrombocytosis.
