Prognosis

See the list below:

Prognosis is not affected by FXI deficiency unless the patient experiences severe trauma or undergoes major surgery without adequate FXI replacement.
If a patient develops hepatitis C after receiving a plasma-derived product, prognosis depends on the secondary viral infection and resultant liver disease.

Patient Education

See the list below:

Instruct patients to inform all of their physicians regarding the diagnosis of FXI deficiency. It is critical that patients provide this information to the physician before any invasive or surgical procedure is performed.
The National Hemophilia Foundation maintains a Web site with extensive information for patients and caregivers.
For excellent patient education resources, see eMedicineHealth's patient education article Hemophilia.
