Objectives: Herapin-induced thrombocytopenia is a relatively common an
d potentially serious adverse complication of heparin treatment, After
heparin withdrawal initiation of an alternative anticoagulant is ofte
n indicated, Org 10172 or Orgaran is a mixture of several non-heparin
low molecular weight glycosaminoglycans with proven antithrombotic eff
icacy, Unlike low molecular weight heparins, Org 10172 has a low cross
reaction rate (about 10%) with the heparin-dependent antibody. Method
s: We present nine patients with heparin induced thrombocytopenia, Org
10172 was prescribed to treat or to prevent a thromboembolic event. R
esults: Seven patients required further parenteral anticoagulant at di
agnosis of heparin-induced thrombocytopenia, Org 10172 was given at pr
ophylactic doses for three patients with a high thrombosis risk and at
therapeutic doses for four patients who presented either a venous or
an arterial thrombosis related to thrombocytopenia, Two patients prese
nted heparin-induced thrombocytopenia four to six years earlier and ne
eded a parenteral anticoagulation treatment in a post-operative period
, Conclusion: For the nine patients, Org 10172 was a safe and effectiv
e antithrombotic treatment, However, strict monotoring of the platelet
count is absolutely mandatory during Org 10172 therapy.
