Computed Tomography Angiography Accuracy in Brain Death Diagnosis
Study Overview
Status
Conditions
Detailed Description
Critically ill patients, presenting Glasgow Coma Score 5 or lower, will be submitted to the Computed Tomography Angiography (CTA) of the skull assessment, and follow a clinical evaluation for brain death, additionally, transcranial Doppler would be applied as the gold standard for brain death.
We will exclude patients whose do not can be submitted to contrast injection, or if a brain death clinical evaluation has been performed prior the CTA.

Measure Description |
Time Frame |
---|---|---|
Assess the presence or absence of contrast medium filling of the intracranial vessels in comatose patients.
Time Frame: 1 year
|
After excluding confounding factors, we will submit comatose patients to CTA.
Immediately after the exam, we will perform clinical evaluation for brain death and calculate CTA sensibility and specificity for this diagnosis.
Time between these two interventions will be measured.
