[Fatal bleeding diarrhoea during dabigatran etexilate therapy].

This is a case report of the fatal course of a 77-year-old bleeding patient in therapy with dabigatran etexilate. The report demonstrates that increased vigilance is needed for elderly patients in risk of decreased renal function. The impaired renal function may be due to seemingly benign conditions such as diarrhoea and low fluid intake during summer months.
