Heparin-induced thrombocytopenia is one of the most difficult problems faci
ng clinicians today. Despite recent understanding of the pathophysiology of
this disorder, there are many unresolved issues about diagnosis, preventio
n, and treatment. In this article, difficulties physicians encounter when f
aced with a suspected heparin-induced thrombocytopenia patient will be revi
ewed as well as our experience in 113 patients with heparin-induced thrombo
cytopenia which highlights the failure of current preventive strategies for
heparin-induced thrombocytopenia. The experience of using warfarin in 51 p
atients with heparin-induced thrombocytopenia will also be reviewed.
