Official title

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

Overview

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.

Primary outcome measures

  • Diagnostic performance similar between computed tomography-angiography and four vessel angiography [Time frame: Periprocedural]

Eligibility criteria

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

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.

Healthy volunteers: No
