Case 21 – update 3

We have now narrowed the differentials:

  • Disseminated intravascular coagulation due to sepsis (unlikely as normal coag)
  • Heparin-induced thrombocytopenia (possibility, but rare in obstetric patients)
  • Thrombotic thrombocytopenic purpura (unlikely – no red cell fragments on film and more common earlier on in pregnancy)
  • HELLP (haemolysis, elevated liver enzymes, low platelets) (unlikely as no elevation in LFTs)
  • Acute fatty liver of pregnancy (unlikely as LFTs and coag normal)
  • Pre-eclampsia (not as BP normal and no proteinuria)
  • Malignant hypertension (BP normal)
  • Dilutional (unlikely as tests repeated and confirmed on film)
  • Immune/idiopathic/autoimmune thrombocytopenic purpura (possibility but ITP is diagnosis of exclusion and usually occurs antenatally)
  • Gestational thrombocytopenia (occurs antenatally)

The HIT risk score is ‘low’ – based on the 4Ts probability score:

There is one other factor at play – she had a blood transfusion.

Questions:

  • How does the blood transfusion relate to her current thrombocytopenia?
  • Would you have transfused the patient?
