|---|
Some patients called for kidney transplantation are anticoagulated with warfarin for indications such as antiphospholipid syndrome, where the risk of thrombosis with reversal may be high. Traditionally, the approach has been reversal of warfarin and treatment perioperatively with intravenous unfractionated heparin. However, this may be complicated by either thrombosis or bleeding if the heparin dose is incorrect. We report the case of a peritoneal dialysis patient warfarinized for antiphospholipid syndrome who was successfully transplanted with an international normalized ratio of 2.1 with neither thrombosis nor bleeding. This may be an alternative to heparin for patients in whom anticoagulation must be maintained.
