The ability of most anticoagulants (except heparin) to cross the placenta and the consequent hemorrhage in the fetus has been recognized for some time (3). A teratogenic effect specifically attributed to warfarin sodium is a more recent finding (7, 9, 10). The following is a case report of a newborn with clinical and roentgenographic features similar to the cases reported previously.
