Correlations between Pathological Changes of the Skull Roof during Childbirth and Localization of Hemorrhages in the Tentorium Cerebelli in Newborns

Vlasyuk VV

Background: At birth in cephalic presentation in fetuses formed a region on the skull roof – area of the periosteal blood stagnation (APS) that persists in newborns. In newborns with minimal birth trauma, in the Tentorium Cerebelli (TC) formed intradural hemorrhages, which do not lead to death. The relationship between these pathological changes has not been studied. The present study aims to examine it.

Method and findings: In a group of 53 neonates and intrapartum dead fetuses it was investigated the correlation between the location of the APS on the skull roof and localization of hemorrhages in TC, consisting of two halves. Two patterns are revealed. First, at a central location in the APS 83.3% of cases there are bilateral uniform hemorrhage in TC, and to an asymmetric, corresponding asynclitic insertion head, - unilateral hemorrhage or prevailing on one side (84%; P <0.01, Q = 0.86). Secondly, the unilateral hemorrhage (or hemorrhage, which is larger in the bilateral hemorrhage) in the TC is predominantly (95.2%) on the side opposite the direction of movement of APS, and more frequently in the left half of the vehicle.

Conclusion: The results of the study showed that the emplacement of the hemorrhage in TC of the neonates and fetuses born in cephalic presentation depends on the location of the APS.
