    Notes: Summary Intracranial haemodynamics were studied in 20 patients with diffuse and focal brain injury and experimental animals with acute intracranial hypertension by the use of TCD ultrasound. The mean flow velocity in the middle cerebral artery (MCA) commonly decreased on the side of the haematoma depending on intracranial pressure (ICP) elevation and cerebral perfusion pressure (CPP) reduction in focal injury. The decrease of the MCA flow velocity returned to normal after treatment. The flow velocities decreased bilaterally and there was no difference between the right and left side in diffuse injury. But the velocities increased in spite of ICP elevation when diffuse cerebral swelling developed. Cerebrovascular CO2 reactivity was impaired in two groups of patients with low Glasgow Coma Scale (GCS) scores. The mean velocity of the MCA and blood flow in the internal carotid artery exhibited flow patterns which changed correlatively depending on CPP reduction in experimental animals. Noninvasive study by use of TCD ultrasound can provide valuable information on variant haemodynamic phenomena in patients with diffuse and focal brain injury.

    Massive traumatic haematoma of the corpus callosum (1986)
    Springer
    Acta neurochirurgica 81 (1986), S. 36-39 
    Details
    ISSN: 0942-0940
    Keywords: Severe head injury ; corpus callosum ; diffuse injury

    Topics: Medicine
    Notes: Summary Five unusual cases with massive haematoma of the corpus callosum caused by blunt head trauma are presented. Aside from the callosal haematomas, intraventricular and subarachnoid haemorrhages or small haemorrhagic foci in the basal ganglia or thalamus were common concomitant lesions on the computerized tomographic (CT) scan. The sites of the impacts were the frontal and occipital areas which were close to the midline and above the level of the corpus callosum. Severe and diffuse brain dysfunction was suggested by the severity of the Glasgow coma score (GCS) and the abnormality on multimodality evoked potentials. An intensive medical treatment such as barbiturate could be promising since a direct surgical approach was dubious because of additional damage to the severely injured brain.
