Hemostatic treatment after tooth extraction in a patient with factor V deficiency.

BACKGROUND

Factor V deficiency is a very rare hereditary coagulation disorder and tooth extraction in the patient with factor V deficiency has not been reported except in one case.

PATIENTS AND TREATMENT

A 38-year-old woman with factor V deficiency was referred for extraction of the impacted lower third molar. After intravenous administration of frozen fresh plasma (FFP) and recognition of an increase of factor V level from 1-31%, upper and lower third molars were extracted. Eighteen and 48 h after the extraction, factor V was intermittently supplemented by injection of 4 and 2 units of FFP, respectively, and factor V was maintained above 12%. To form fast coagula and to protect the wound, the lower extraction socket was filled with a fibrin glue composed of factor XIII and fibrinogen (Beriplast P) and a plastic splint was applied. The wound was healed and epithelized within 2 weeks after the extraction without any bleeding or infectious consequences.

CONCLUSION

Extraction in the patient with factor V hereditary deficiency is safely performed by both supplementation of factor V and application of local hemostasis.
