A case of dental surgery intervention for a hemophilia A patient

Hemophilia A is a genetic coagulation disorder associated with a deficiency of clotting factor VIII (FVIII). It can be inherited or acquired and have different levels of severity. The present case report describes a male patient with FVIII deficiency who underwent dental surgical treatment. The patient was a 70-year-old male with a prosthetic mechanical aortic valve who had undergone ascending aortic replacement surgery and coronary artery bypass surgery. He also had a history of cerebral infarction with right paraplegia. Therefore, he visited our hospital for surgical dental treatment. The patient underwent blood tests and imaging to assess the severity of hemophilia and the condition of the surgical area. The treatment plan for the day of surgery was to ensure that markers for bleeding tests would not be increased and prolongation of the partial thromboplastin time (PTT) would remain mild; accordingly, the patient was administered FVIII before the surgical treatment under local anesthesia. The blood examination revealed a mild prolonged PTT and slight changes in platelet count and FVIII level. There was no subsequent bleeding or complications at follow-up, and the wound had healed completely without abnormalities.
