[Individual differences in the venous formations of the parasagittal area of the neonatal cranial vault].

Diagnostics and treatment of intracranial hemorrhages in newborns, being one of the actual problems of pediatrics, are performed taking into account the parasagittal zone structure. To reveal borders of the parasagittal area in newborns in order to find optimal points for puncture of the superior sagittal sinus and subdural hematomas in this area, the investigation has been undertaken. One hundred mature and 50 premature newborns have been studied, their cerebral veins are injected with contrast mass, x-rayed and then the preparations fixed in 3%, 5% and 10% formalin are made ready. It has been stated that for puncture of the newborn subdural space two points should be used: a) on the coronal cross-line of the anterior fontanel, 20 mm away of its middle line at either side (in mature newborns) and 10 mm (in premature newborns), b) within the limits of the sutura lamboidea 30 mm the sagittal suture (in mature newborns) and 15 mm from the sagittal suture (in premature newborns).
