Dental extraction in congenital factor Vll deficiency with inhibitor – a case report

Abstract

Background Hereditary factor VII (FVII) deficiency is a rare bleeding disorder with autosomal recessive inheritance, and FVII deficiency with an inhibitor is extremely rare. There is sparse information in the literature on the management of tooth extraction in patients with FVII deficiency and an inhibitor. Case description We report the case of a five-year-old child with FVII deficiency and an inhibitor who underwent dental extraction. The child had had multiple bleeding episodes including intracranial haemorrhage and had a history of severe allergic reaction to the infusion of recombinant FVII. The tooth was extracted using lignocaine gel and the antifibrinolytic agent oral tranexamic acid. Conclusion The extraction of a deciduous tooth in a patient with FVII deficiency and an inhibitor was undertaken without bleeding complications. There are currently no guidelines regarding management of this type of case. Further studies and evidence are required so that management can be standardised.
