Venesection bruise in anticoagulant patient. Close-up of the arm of an 83-year-old female patient receiving anticoagulant drugs, showing a large bruise following venesection. Venesection is the practice of obtaining access to a vein either for blood taking or intravenous (IV) therapy. Anticoagulants are blood-thinning drugs. As such any injury to blood vessels takes longer to clot. Therefore, a patient receiving an anticoagulant will bruise much more easily.
