Perioperative Management of Type 2N Von Willebrand’s Disease with Recombinant Factor VIII in a Patient Undergoing Knee-Replacement Surgery

Abstract

Type 2N Von Willebrand's disease (2N VWD) is a rare, recessively inherited bleeding disorder, comprising 1-2% of all VWD patients, usually manifesting as a mild bleeding diathesis. Treatment includes desmopressin (DDAVP) or intermediate purity plasma-derived FVIII concentrates containing residual VWF. We present a case of a 75-year-old gentleman, incidentally diagnosed with type 2N VWD in 2002 on routine blood testing before surgery with an ISTH bleeding score of 1-2, who was treated with recombinant FVIII preoperatively.
