Diagnosis of head trauma
- Clinical. The diagnosis of head trauma can be obvious when it is reported by the affected person conscious after unconsciousness, or by those around him, or suspected in a person unconscious in front of a wound, a contusion or a significant bruise of the leather. hairy.
- Scanner. The scanner makes it possible to determine the lesional consequences of the head trauma (fracture, hemorrhage, cerebral contusion, edema, etc.). Be careful, imaging can still be normal in some cases. In fact, lesions may appear in the hours that follow and therefore not visible if the scanner is performed early after the accident. In addition, certain lesions, axonal ruptures for example, are not detectable by the usual CT or MRI. Clearly, normal CT or MRI results should not be 100% reassuring and monitoring of the clinical course of the person who has suffered the head trauma is essential. Especially since there was an initial loss of consciousness or suspicious neurological symptoms.
- X-ray of the skull. It has no interest in the search for intracerebral lesions (intracerebral hematoma, contusions, ischemia, edema, engagement syndrome, etc.) or extra-cerebral (extra-dural or sub-dural hematomas) which cannot be demonstrated by simple X-rays delivered by radiography. Noting a fracture line on an X-ray of the skull after a head trauma is not necessarily a sign of seriousness. Therefore, a normal skull x-ray after head trauma does not justify the absence of monitoring. Skull fracture or not, monitoring is essential as soon as the head trauma has been judged to be severe, a fortiori if it is accompanied by an initial loss of consciousness and neurological disorders upon awakening.
Prevalence
Each year, 250 to 300 people / 100 are victims of CD. 000% are considered severe.
