Like you so often hear...it depends.  Factor XI deficiency is most commonly found
in Ashkenazi and Bedouins.  Recently it has been shown that those with bleeding diathesis
(many people with XI deficiency are asymptomatic) also have
platelet disorders.

The treatment of choice in those patients with prior bleeding problems seems to be desmopressin. Without a history of problems I would do a bleeding time before any treatment. If for some reason desmopressin is needed and not available, fresh frozen plasma may be used. Cryoprecipitate is a poor choice, because it only replaces fibrinogen and factor VIII/

Good Luck.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
