Hereditary factor VII deficiency is a rare disorder transmitted by autosomal recessive pattern and its clinical feature is extremely variable. Recently we have experienced a case who was performed herniorrhaphy without any cryoprecipitate or fresh frozen plasma replacement therapy. A 21-year-old patient who had undergone intermittent nasal bleeding was noted for prolonged prothrombin time(INR of 1.5). The level of the factor VII of the patient was decreased at 22% of the normal activity. His parents had normal level of factor VII activity. Both his sister and brother had decreased level of factor VII at 41% and 24% respectively. Herniorrhaphy was performed without factor replacement therapy and there was no visible postoperative bleeding. We report here a case of factor VII deficiency performed an operation successfully without any replacement therapy.
