Spontaneous rectal sheath bleed while on DOAC anticoagulation.

A man in his 80s was transferred from his nursing home residence with sudden onset right-sided abdominal pain. The nursing home staff reported that he was walking to the bathroom when he became diaphoretic, reported he was feeling unwell, then sat on the ground and was reluctant to move. Past medical history was significant for longstanding atrial fibrillation for which he was taking apixaban 2.5 mg twice daily. A CT scan of the abdomen and pelvis was performed which showed a 21×11 cm rectus sheath haematoma on the right extending into the lumbar region. Surgical review advised no invasive intervention. Two units of red cell concentrate were transfused and he was monitored for 5 days before being transferred back to the nursing home.
