CT-Angiography Versus Angiogram as Ancillary Tests in the Determination of Death by Neurologic Criteria

A Comparison of Computed Tomography-Angiography Versus Four-vessel Angiography in the Determination of Brain Death

Diagnostic performance of a novel protocol for computed tomography-angiography, as ancillary test in the determination of complete cerebral infarction, in comparison to four vessel angiography.

Inclusion Criteria:

• Adults 18 years or older
• Ongoing critical care due to severe acute brain injury
• Four vessel angiography necessary for the determination of complete cerebral infarction, according to Swedish legislation

Exclusion Criteria:

• Treatment with extracorporeal membrane oxygenation (ECMO)
• Radiologic examination by computed tomography deemed too challenging due to respiratory or circulatory instability, as determined by responsible clinician
