History And Clinical Findings:
A 63-year-old man was admitted to a surgery department with fracture of the acetabulum and luxation of the hip joint. Eight days after intracondylar nail-extension during subcutaneous heparin prophylaxis he developed a dramatic deterioration of his condition with severe abdominal pain and fever and was admitted to our hospital.
Investigations:
White cell count was 12,000/microliter, C-reactive protein 7.90 mg/dl. CT-scan, abdominal ultrasound, mesenteric angiography and exploratory laparotomy revealed no pathological findings. At day 13 abdominal ultrasound showed adrenal haemorrhages on the right. Together with a drop in platelet count below 50,000/microliter, adrenal haemorrhage caused by heparin-induced thrombocytopenia (type II; immunological [HIT II]) was suggested.
Therapy:
After discontinuation of heparin and starting therapy with recombinant hirudin and hydrocortisone, a dramatic clinical recovery followed within 24 hours. One year after the initial diagnosis the patient is in a good condition.
Conclusion:
When abdominal pain, hypotension and fever occurs with a drop in platelet count during heparin therapy HIT II should be considered. An early diagnosis is essential for treatment of this life-threatening complication at an early stage.
