Follow-up

Further Outpatient Care

Ideally, a hematologist who has experience in the diagnosis and management of inherited bleeding disorders should monitor individuals with severe factor V deficiency.

Deterrence/Prevention

  • Factor V deficiency is an inherited disorder; no known means of prevention exists.
  • Immunize patients who may require plasma-derived coagulation factor concentrates with hepatitis B vaccines.

Complications

Complications of factor V deficiency are directly related to the site of bleeding (eg, hemarthrosis, intracranial hemorrhage, uncontrolled postoperative bleeding).

Prognosis

The prognosis of factor V deficiency is good with diagnosis and proper treatment.

Patient Education

  • Give patients and families instruction and educational materials to enable them to understand factor V deficiency.
  • For excellent patient education resources, visit eMedicine's Blood and Lymphatic System Center. Also, see eMedicine's patient education article Hemophilia.

Miscellaneous

Medicolegal Pitfalls

  • Because factor V deficiency is treatable, albeit rare, consider it in the differential diagnosis when confronted with a bleeding patient. As always, when confronted with a potential coagulopathy, physicians must respond quickly with their evaluation and management to avoid catastrophic hemorrhage.
  • Child abuse and congenital coagulation disorders may present with similar neurologic symptoms and radiologic findings. In these patients, coagulation tests are mandatory. If the results of the tests are abnormal, enable early deficit substitution and prevent inappropriate suspicion or accusation of caretakers.

Special Concerns

  • Factor V deficiency must be differentiated from combined deficiency of factors V and VIII, which is an entirely separate disorder observed in a number of populations around the world. Family history and a very abnormal aPTT may suggest factor V-VIII disorder; factor VIII and factor V assay results will range from 15-20%, which would help in the diagnosis of this complication.7
