title: Factor VII deficiency first observed at preoperative routine clotting test.
abstract: Factor VII deficiency was first observed in a 24-year-old female in the routine clotting test for tooth extraction. Her factor VII was 22%, mildly below normal limits. Factor IX complex was not administered as replacement therapy when her impacted tooth was extracted. There was no sign of abnormal postoperative bleeding. As this disease was a rare disorder, the minimum safe level of factor VII for tooth extraction was unknown. We had a opportunity to study a patient with this disorder observed in the preoperative routine clotting test for tooth extractions.
