Patrimonial intracranial trauma - a lesion of a brain of the child during sorts in which basis break of vessels and intracraneal hemorrhages lay.

Etiology and pathogenesis. Fine hemorrhages can result from an emigration of erythrocytes; the factors promoting occurrence of an intracranial birth trauma, are a pathology of pregnancy (disease of mother, an excessive mechanical prelum of a head of a fetus at passage on patrimonial ways (a narrow basin, anomalies of position of a fetus), obstetric grants.

As contributing factors morphological uncompleteness and variants of a structure of vessels and the vascular wall, the lowered resistance of capillaries, the low maintenance of a prothrombin and a fibrinogen in bloods of newborns and possible defects of coagulating system of a blood, imperfection of a nervous regulation of a vascular tonus serve. The serious oxygen failure and an acidosis also contribute to occurrence of hemorrhages owing to rising permeability of vessels, development of a hypoxia of a brain. Depending on localization distinguish following basic kinds of hemorrhages: epidural hemorrhages (intracranial cephalhematomas) - at damage of bones of a skull; subdural - at a lesion of venous sine; subarachnoidal - in a soft cerebral environment and in subarachnoid space.
