Abstract
The etiology of the subdural haematoma of the infant (SH)is most often injury. The fall from a height at home (80-100 cm)is usually accompanied by the head impact on an underlay and so bleeding occurs into the space under the dura mater.
Similar bleeding appears also as a result of violence led by another individual,the direct contact of the head - actively by the hit with a pointless instrument or passively by the head impact on an underlay after exuviation. The syndrome of the socalled "shaking of the child"- shaken head (baby)syndrome - could also lead to the supratentorial damage of the pial blood vessels when the child is seized and his/her head is been repeatedly moved in the anteroposterioric direction,but the accompanying contact of the head with the underlay (shaken impact syndrome)is considered to be the more probable mechanism of bleeding.
