Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In France the diagnosis of brain death relies on electroencephalography (EEG) or cerebral angiography. Concerning the latter a time of 6 hours is mandatory between the clinical diagnosis and the realization of the cerebral computed tomography (CT) angiography. Transcranial doppler (TCD) is not recommended in the french guidelines for the diagnosis of brain death. In other countries, some flow patterns allow to confirm the diagnosis of brain death. The hypothesis of our study is that TCD could shorten the time between the clinical diagnosis of brain death and the realization of the CT angiography.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Usual

CT angiography is performed 6 hours after the clinical diagnosis of brain death.

No interventions assigned to this group

TCD

When the diagnosis of brain death is made, TCD is performed and then every 2 hours until the flow patterns compatible with brain death are found. Then a CT angiography is performed.

Transcranial doppler

Intervention Type OTHER

A TCD is performed on all cerebral arteries (mean cerebral arteries, anterior cerebral arteries, basilar trunk, vertebral arteries and carotid arteries) until a flow pattern compatible with brain death is found
