Blepharoplasty and von Willebrand. Is it too risky?

I am interested to have a blepharoplasty and possibly a facelift too. I have a mild-to-moderate von Willebrand disease which requires replenishment with coagulation factor VIII, using Hemate or desmopressin, starting at the time of the surgery and continuing for up to 5-6 days post surgery. I want to know whether this is risky and what is the clinical experience with facelift and blepharoplasty in von Willebrand patients. Thanks a lot in advance. any advice is most precious.
