Acute adrenal failure following anticoagulation with dabigatran after hip replacement and thrombolysis for massive pulmonary embolism.

A 75-year-old woman presented 9 days post-total hip replacement with sudden onset of shortness of breath and fever. She had been discharged taking dabigatran. The patient was treated for sepsis with antibiotics and fluids. However, she deteriorated and was transferred to the intensive care unit. Following a 10 s asystolic episode the patient was thrombolysed with alteplase for presumed massive pulmonary embolism. Initially, her blood pressure and oxygen saturation improved. However, over the next few days, she remained persistently hypotensive. A CT scan of her chest, abdomen and pelvis demonstrated bilateral adrenal haemorrhages. A short synacthen test confirmed acute adrenal failure.
