The authors of this book have aimed to meet the needs of the practicing physician in the field of hemorrhagic disorders. They state that in many past treatises on the subject "undue emphasis [was] placed on disorders of the coagulation mechanism, at times to the exclusion of other disturbances of the hemostatic mechanism." In this case, however, the authors have succeeded in presenting all factors involved in the complex mechanisms responsible for abnormal bleeding. They stress the clinical approach and therapy. The aid rendered by the laboratory is not neglected, but it is made clear that, significant as they are, laboratory studies are only one phase of the management of the patient. The first chapter deals with the normal hemostatic process. Classification, vascular defects, thrombocytopenias, coagulation, combined disturbances, anticoagulants, fibrinolysis, obstetric problems, dysproteinemias, treatment, and heredity are covered in the other chapters. The appendix deals adequately with laboratory procedures.
