ABSTRACT
As in the case of adults, there are three main goals in the monitoring of severe head trauma in children: to prevent or minimize the apparition of secondary lesions, to optimize treatment, to help make precise prognosis. The basic monitoring is composed of repeated clinical examinations, brain radiological imaging and control of vital parameters (blood pressure, temperature, PaO2 (SpO2), PaCO2 (FETCO2), haemoglobin, haematocrit. On the other hand, during specific brain monitoring, the brain perfusion (TCD, intracranial pressure), the electrical activity of the brain and sometimes the brain oxygenation (SvjO2) are controlled. The data obtained from the brain monitoring must always be interpreted carefully. A child with a severe head trauma, in ICU, always requires constant and competent medical attention.

A case is reported of a patient with a traumatic aneurysm of the intracranial part of the carotid artery occurring after a traffic accident. The patient was admitted in coma (Glasgow score 5), and presented with a depressed fracture of the frontal and parietal bones, a fracture of the left petrous pyramid and of the left anterior clinoid process, as well as of the right tympanic bone and temporomandibular joint. The borders of the left carotid canal seemed unaltered. Despite the lack of localised neurological signs, cervical and transcranial Doppler ultrasonography was carried out. Intracranial carotid blood flow was found to be altered on both sides. Angiography showed a false carotid aneurysm on the left side (carotid siphon portion C3), and a moderate irregular stenosis of the C2 part on the right. There were no brain lesions on the CT scan. Prophylactic treatment with heparin was started. The patient recovered normal consciousness within a fortnight. The false aneurysm increased in volume and was treated by embolisation. Flow speeds in the carotid siphons also returned to normal. The usefulness of routine screening of patients with petrous bone fractures with Doppler ultrasound is discussed.
