title: PTA deficiency (factor XI deficiency). Report of a case.
abstract: A case of a relatively rare coagulopathy has been presented. The mode of inheritance and the incidence of the disease have been discussed. Methods of screening, diagnosis, and treatment of PTA deficiency have been suggested. We have concluded that if a coagulation screen for patients about to undergo oral surgery in a hospital is contemplated, either a partial thromboplastin time or a thromboplastin generation time should be included.
