Splenectomy complicated by sustained extreme thrombocytosis and extensive portosplenomesenteric vein thrombosis in pyrimidine 5′-nucleotidase deficiency

Abstract

Reactive and redistributional thrombocytosis is a well-known postsplenectomy occurrence. Usually it is transient and it rarely reaches extreme levels. We report a rare case of haemolytic anaemia where splenectomy was carried out following trauma to a massively enlarged spleen and was followed by extreme sustained thrombocytosis associated with extensive portal, splenic and mesenteric vein thrombosis despite standard antithrombotic prophylaxis.
