She has been, taking 12 mg acenocoumarol by mistake for 5 days before admission because of atrial fibrillation. INR was 20 during an admission.

The cut section of gall bladder showed stone, haemolysed blood and blood clots. Choledochotomy showed only blood clots within the duct. The treatment lasted long period and patient died because of multiorgan insufficiency in the course of sepsis.
