ABSTRACT

Introduction: brain death definition has evolved from the medical, lawful and cultural point of view, that´s why it is not considered only by cardio-respiratory diagnostic criteria, it is also considered by irreversible waste of the cerebral functions. Brain death has been acknowledged and accepted like the patient´s death. Transcranial Doppler is an instrument test frequently done to brain death diagnosis.
Objective: to describe the results of the ultrasonography patterns finding in patients with brain death.
Methods: a prospective, descriptive and transversal trial was realized at the ¨General Calixto García¨ Teaching Hospital, between January 2014 and December 2015. Forty-seven patients who had brain death diagnosis represented the research universe and the sample was 44 patients in whom was used the transcranial Doppler sonography to confirm this diagnosis.
Results: this research showed masculine sex prevalence, the age average was 41.9 years and the brain trauma was the first cause of brain death. The temporal brain window was the most used and the middle cerebral artery was the most explored. It was found isolated systolic spikes as sonography pattern predominant of brain death.
Conclusions: this trial showed high sensitivity and specificity of the transcranial Doppler in the brain death diagnosis.
