Warfarin-associated intracranial haemorrhage in pregnant woman with double mechanical valve replacement: a case presentation

Abstract

Abstract Background Management of warfarin-associated major haemorrhage in prosthetic valve diseases is difficult as there is a fine line between haemorrhage and thrombosis. An individual’s propensity towards thrombosis, such as pregnancy, makes this situation even more complicated. Cases like these are very rare in the literature. Case presentation A 26 weeks pregnant, gravida two, para one, 35-year-old patient with prosthetic aortic and mitral valves presented to an external emergency clinic with clouding of consciousness. Her international normalised ratio(INR) was 8.9 at presentation. Brain MRI revealed a left subdural haematoma with no significant mass effect. Warfarin treatment was discontinued. On the second day of follow-up, she was referred to our centre for further evaluation of her clinical deterioration. She was haemodynamically stable on admission to the intensive care unit and followed up with a stable condition until the fourth day when she developed right eye drop and subsequent loss of consciousness. Her haematoma was surgically evacuated, and her condition improved. Eventually, she and a healthy newborn were discharged. Conclusion Intracranial haemorrhage during pregnancy is a relatively rare complication that requires a multidisciplinary management plan. Although the thrombogenic risk is high, it is vital to complete a reversal of warfarin anticoagulation in pregnant women with major bleeding.
