    Abstract:
    Heparin induced thrombocytopenia is characterized by often dramatic evolution of thrombotic arterial and venous complications. These occurred or are worsened in curative or preventive heparin therapy and the treatment remains delicate. The authors report 32 observations of thrombocytopenia complicated with thromboembolic events; seven deaths are to mention. The tests of platelet aggregation with standard heparin and platelets poor patient's plasma confirm the diagnosis in 28 cases of 30 very early studied and in 2 cases around the 6th day only after the stop of standard heparin. The choice of anticoagulant therapy is carried out the negative tests of platelet aggregation with low molecular weight heparin (L.M.W.H.) (CY 216, CY 222 Choay, PK 10109 Pharmuka). In L.M.W. heparin therapy, clinical and biological improvement is obtained in 26 cases of 30 treated cases. In three cases, the rapid climbing of platelet countings is not present although negative tests of platelet aggregation with selected L.M.W.H. In one case, after a initial climbing of platelet countings, the thrombocytopenia recurs rapidly with L.M.W. heparin after a operation. The immediate or secondary passage with K-antivitamins, platelet antiaggregant stabilized medium and long term's evolution.
