title: Acute subdural haemorrhage in the postpartum period as a rare manifestation of possible HELLP (haemolysis, elevated liver enzymes, and low-platelet count) syndrome: a case report.
abstract: BACKGROUND
  The HELLP syndrome (haemolysis, elevated liver enzymes, and low-platelet count) occurs in about 0.5 to 0.9% of all pregnancies. With occurrence of thrombocytopaenia, it signals for several potentially lethal conditions such as complete or partial HELLP syndrome, thrombotic thrombocytopaenic purpura and acute fatty liver of pregnancy.
  
  
  METHODS
  A previously healthy 27-year-old, Sinhala ethnic primigravida with pregnancy-induced hypertension was admitted at 38 weeks of gestation with lower abdominal pain and a blood pressure of 140/90 mmHg. She underwent emergency Caesarian section due to faetal distress giving birth to a healthy baby girl. Since postpartum day one, she was having intermittent fever spikes. All the routine investigations were normal in the first three weeks. Platelet count started dropping from post-partum day-20 onwards. On day-23, she had developed a seizure and computed tomography scan brain showed a subdural haemorrhage. She had a platelet count of 22,000 × 109/liter and was managed conservatively. She also had elevated liver enzymes, lactate dehydrogenase and bilirubin levels. Blood picture on day-24 showed haemolytic anemia. On day- 36, patient again developed seizures and she was having intermittent fever with generalized headache and signs of meningism. Computed tomography scan revealed an acute on chronic subdural haemorrhage.
  
  
  CONCLUSIONS
  Hypertensive disorders in pregnancy should be managed as high-risk throughout the postpartum period. Development of thrombocytopaenia can be considered as an early warning sign for HELLP, thrombotic thrombocytopaenic purpura or acute fatty liver of pregnancy which are lethal conditions. Prompt recognition of intracranial haemorrhages and early neurosurgical intervention is lifesaving.
