Due to craniocerebral trauma in the structure of the brain may experience different types of violations. Depending on the force of the impact and mechanism of the injury they can be microscopic and macroscopic. If a patient with less severe TBI large structural damage may not be, when a severe open or closed injury trauma effects can be disastrous. Details on the types and posledstvijah traumatic brain injury read on neurosys.ru.
Open craniocerebral injuries are those injuries that penetrate through the scalp and skull box, touching Dura and brain tissue. Such injuries a person may get due to a gunshot wound, a blow with a sharp object, fracture of the skull, when the security impact of a heavy object.
The emergence of closed craniocerebral injury, as a rule, preceded by hitting them on some object or a sharp shake. Very often in such cases suffer from temporal lobe and frontal lobe, there are breaks or tears of blood vessels, nerve fibers. Due to the excessive permeability of the damaged vessels in the zone of injury may be formed hematoma (subdural or epidural), happen subarachnoid or intracerebral hemorrhage.
A concussion is a temporary post-traumatic altered level of consciousness, a reversible process (for example, loss of memory or consciousness). In this state the person is from a few seconds up to six hours or more. Thus, there are no large structural brain damage.
Hematoma of the brain is the accumulation in the medulla or around the blood. This undesirable consequence can be as after penetrating and closed after damage. Hematomas are intracerebral, subdural and epidural.
In the formation of subdural hematoma blood accumulates between the arachnoid and the Dura membranes. Often, the occurrence of acute subdural hematoma caused by the breaking of the crust or veins of the brain, the gap communicating veins between the sinuses of the Dura and cortex. Such unwanted education most likely to occur after accidents and falls. This hematoma may exert undue pressure on the brain, increases the likelihood of development of edema and increased intracranial pressure. If sick time is not treated or if it will not bring the desired effect, possible death.
If blood collects between the Dura mater and the bones of the skull, the person is diagnosed with an epidural hematoma. This type of hematoma is arterial bleeding, which usually occurs when a fracture of the temporal bone. Man with epidural hematoma requiring emergency assistance, otherwise his condition may rapidly deteriorate until the death of the patient. It is extremely rare epidural venous hematoma. Their size is negligible and mortality is not high.
Intracerebral hematomas are called clusters of blood directly into the brain tissue. They often arise from the progression of the injury. If the hematoma is not noticed in time, it is accompanied by various complications (increased intracranial pressure, development of functional insufficiency of the brain stem, disk herniation, etc.).
