ABSTRACT

Introduction: The diagnosis of brain death for organ donation purposes requires a confirmatory test to shorten the times of the process.
Objective: To describe the characteristics of Transcraneal Doppler sonograms recorded (DTC) in patients with clinical diagnosis of brain death.
Method: We conducted a longitudinal study of the characteristics of the records of DTC, in two evaluations periods, in patients with clinical diagnosis of brain death, admitted to the polyvalent intensive care unit of the University Hospital: Manuel Ascunce Domenech in Camagüey city, during one year (June 2011 to June 2012). 34 patients with clinical and sonographic diagnosis of brain death were included.
Results: We explored the anterior and middles cerebral arteries and the extracranial internal carotids for spectral morphology recordings. Males predominated and the average age was 45 years. The main cause of death was hemorrhagic stroke (55.9%). Separation patterns diastole-systole and reverberating flow dominated the first evaluation and were followed by systolic spikes in 11.8% of cases.
Conclusions: In the studied patients, with prior clinical confirmation of brain death, separation pattern diastole-systole and reverberating flow followed by systolic points suggest that it is not necessary to extend the evaluation further more.
