Background: Cerebral venous sinus thrombosis (CVST) is a rare, high-risk, and easily misdiagnosed disease. Currently, there are case reports of hem coagulase-induced thrombotic events, but no reports of CVST being associated with hem coagulase.
Case summary: A 35-years-old woman presented to the outpatient clinic with a severe headache and sudden memory loss with intravenous hem coagulase for postoperative bleeding after uterine fibroids surgery. Abnormal neurological signs included slowed reactions, poor memory, and decreased numeracy. Magnetic resonance imaging and computed tomography scan showed multiple cerebral infarcts, and the infarct area was non-arterial. Brain magnetic resonance venography showed obstruction of the left sigmoid sinus. High-resolution magnetic resonance imaging of the left sigmoid sinus showed abnormally high signal. The patient was treated with a subcutaneous Low-Molecular-Weight Heparin Sodium injection 0.4 ml, twice a day (7 days), and oral Warfarin Sodium 3 mg, once a day, while monitoring the international normalized ratio, adjust the warfarin sodium dosage according to the international normalized ratio level. One month later, the patient had no neurological symptoms and her cognitive function returned to normal.
Conclusion: hem coagulase may be a contributing factor to CVST in patients undergoing uterine fibroids surgery and should be administered intravenously with caution.
