At the closed craniocerebral trauma changes

At the closed craniocerebral trauma changes in all cerebral covers become perceptible. In a firm cerebral cover ruptures of capillaries, a swelling and myelin disintegration, damage of axial cylinders are observed. At all forms of a traumatic lesion of a brain at early stages the aseptic serous meningitis develops. Throughout 4-5 кед these changes either disappear, or the arachnoiditis of various buy ultram localisation, or cystic, often accompanied by disturbance , a hydrocephaly develops.
At the moment of an acute trauma to difficult and diverse influence is exposed as well substance of a brain. The trauma always causes diffusive changes of a nervous tissue. These changes in a part of cases are shown only by disorders of function of nervous cells. Others break structure of the nervous cells, which part , is reversible. More serious diffusive changes cause dystrophic process in the nervous cells, coming to an end and formation of cells-shades. Recently attach significance to changes of membranes of the nervous cells, explaining transition of functional changes of a brain in organic (E.M.Burtsev, Beavers, 1986). D.М. Feeney, J.С. Baron (1986) possibility of such transformation bind with it is long proceeding process .
At a concussion of the brain functional disturbances prevail over organic (N.J.Vasin, S.I.Salazkina, 1981).
Besides, at all kinds of traumas the cerebral substance is sharply displaced in a blow direction. Thus different sites of a brain suffer unequally. Damages can arise in a blow and coutrecoup place (at an opposite wall of a skull about which the displaced brain hits). At shift the cerebral substance hits about osteal prominences of the basis of a skull, as a result its fixed departments (area, a cerebral trunk, places of an exit of craniocerebral nerves on the basis of a brain), and also places of contact of a cerebral tissue with tissues of other density (vessels, cerebral sine) especially suffer. phentrimine
The brain bruise represents a combination of functional and irreversible morphological changes. Depending on its localisation there is a certain clinical picture.
