Abstract
Congenital factor V deficiency is a rare inherited incomplete autosomal recessive disorder. The condition is characterized by hemorrhagic diathesis, including nasal bleeding, hypermenorrhea and bleeding after extraction. Laboratory tests reveal prolonged prothrombin, activated partial thromboplastin times and reduced activity of factor V.
We report a case of congenital deficiency in factor V in a patient undergoing a tooth extraction.
A blood transfusion with fresh frozen plasma is the accepted treatment for arresting hemorrhages in patients with a factor V deficiency, as there is no pharmaceutical preparation of coagulation factor V available.
In this case, as the clinical examination results were significantly better than the pre-extraction examination, a good outcome was able to be obtained by using local hemostasis.
Congenital factor V deficiency clinical examination results may show great variation, so clinicians should conduct thorough preoperative evaluation and observe the patient carefully after treatment.
