title: Postoperative bleeding with factor VII deficiency: case report.
abstract: Factor VII deficiency was diagnosed during haematological investigation of a patient with multiple occurrences of postoperative bleeding after surgical extraction of an impacted upper left canine. The bleeding was eventually stopped with local measures without resorting to blood product transfusion which may have been necessary if local measures had failed to control bleeding. Abnormalities were also found in subsequent blood profiles and coagulation tests in other members of the patient's family.
