Objective

To analyze the anticoagulant treatment of patients with low molecular weight heparin-induced severe type II thrombocytopenia complicated by multi-site embolism, and to provide reference for rational use of anticoagulant drugs in clinic.

Methods

Clinical pharmacists participated in the diagnosis and treatment of a patient with heparin-induced thrombocytopenia(HIT) with multiple thrombus. According to the patient’s pathophysiology, auxiliary examination and other conditions, combined with literature review and individualized medication monitoring, they assisted in formulating and optimizing the anticoagulant treatment plan, improving the quality of pharmaceutical care, and promoting clinical rational drug use.

Results

The clinical pharmacist assisted in identifying the cause of thrombocytopenia, with a 4T’s HIT score of 7 (indicating high probability of HIT) and positive HIT antibody(HIT-Ab) (6.2 U·mL-1). Following argatroban anticoagulation therapy, the patient’s blood platelet count (PLT) improved from 11 to 87 ×10 ·L-1, while D-dimer levels peaked at 60.08 mg·L-1 FEU before declining to 30.60 mg·L-1 FEU. Activated partial thromboplastin time (APTT) remained stable at approximately 50 seconds. No new thrombotic or hemorrhagic events occurred, and the clinical outcome was favorable.

Conclusion

Although low molecular weight heparin-induced thrombocytopenia is rare, it still needs clinical attention. Clinical pharmacists can assist physicians in formulating individualized treatment plans for patients from the perspective of pharmaceutical professionals to ensure the rationality of clinical drug use.
