[Myocardial infarct complicating thrombopenia induced by pentosan polysulfate].
The authors report a case of thrombopenia induced by pentosane polysulfate (PSP), complicated by a myocardial infarction. Biological tests showed a platelet pro-aggregating effect of PSP and an IgG immunoglobulin fixed to the platelets. A review of the literature shows that PSP-induced thrombopenias must be known as well as those induced by heparins and that they have similar complications. The thrombopenia may persist with an inappropriate substitution with heparin and the clinical picture may be aggravated. It is desirable to carry out systematic screening for a cross-allergy and prevent it by using anti-vitamin K.
