Heparin induced thrombocytopenia is a rare complication of heparin therapy that usually occurs within initial 5 to 10 days of heparin exposure. We present a rare case of delayed onset heparin induced thrombocytopenia that occurred one week after cessation.

OBJECTIVE To investigate tolerability and efficacy of low molecular weight (LMW) heparin therapy in patients with severe Raynaud's phenomenon. METHODS A prospective parallel group study comparing patients receiving regular subcutaneous LMW heparin (n = 16) with a matched control group (n = 14). Endpoints were change in Raynaud's attack severity, non-invasive vascular studies or serum levels o...

Heparin-induced thrombocytopenia is a rare immune-mediated complication of heparin therapy, characterized by decrease in platelet count more than 50% the baseline. Typically occurs between 5 to 10 days after initiation heparin. Incidence United States ranges from 0.2% 3.0%, depending on population studied and diagnostic criteria used. HIT has been categorized into two types: type I II. While be...

A case of heparin-induced thrombocytopenia with thrombosis (HITT) is described. The patient, treated for several days with porcine Ca-heparin at a dosage of 10,000 IU/day, presented severe thrombocytopenia (Plt 36 x 10(9)/L), intermittent right leg ischemia, and a positive heparin-induced platelet aggregation assay. We promptly discontinued heparin and started picotamide, an antiplatelet drug. ...
