Computed Tomography Angiography to Brain Death Assessment
The purpose of this study is to assess the reliability of computed tomography angiography (CTA) to diagnose brain death, face of several conditions that make impossible to define such diagnosis using clinical criteria exclusively.
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Computed Tomography Angiography to Brain Death Assessment|
- Assess the presence or absence of contrast medium filling of the intracranial vessels in comatose patients. [ Time Frame: 1 year ] [ Designated as safety issue: No ]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.
|Study Start Date:||November 2013|
|Estimated Primary Completion Date:||November 2014 (Final data collection date for primary outcome measure)|
