Congenital factor VII (FVII) deficiency is a rare hemorrhagic disorder, and, in affected patients, surgery is likely to cause excessive bleeding. In this article, we report the first case of total hip arthroplasty in a patient with severe congenital FVII deficiency in which recombinant activated factor VII (rFVIIa, NovoSeven) was successfully used to manage bleeds. The patient was a 68-year-old woman with severe congenital FVII deficiency, who suffered from a hemorrhagic arthrosis of her left hip joint. We administered rFVIIa as intermittent bolus infusions both perioperatively and postoperatively; dosing was based on the results of a preoperative rFVIIa challenge test. During surgery and the 3-day postoperative treatment period, we observed normal hemostasis with no excessive bleeding or complications.
