Diagnosis of brain death by transcranial Doppler sonography.
Delays in diagnosis of brain death have definite consequences for the organ retrieval and transplantation process. It is advisable to use accurate diagnostic methods. Transcranial Doppler sonography is a well-accepted technique for diagnosing cerebral circulatory arrest. However, in some cases, the access to the intracranial circulation via the temporal window is difficult. In 43 brain-dead pat...
متن کاملDiagnosis of brain death by transcranial Doppler sonography
The blood flow velocities in the basal cerebral arteries can be recorded at any age by transcranial Doppler sonography. We examined nine children with either initial or developing clinical signs of brain death. Soon after successful resuscitation increased diastolic flow velocities indicated a probable decrease in cerebrovascular resistance; this was of no particular prognostic importance. As s...
متن کاملRole of Transcranial Doppler Sonography in Confirmation of Brain Death
The aim of the study was to determine the specificity and sensitivity of Transcranial Doppler Sonography (TCD) as a confirmatory test for diagnosis of brain death and to assess the possibility of adding this test to the protocol for diagnosis of brain death in ICU. TCD examination was done in 20 patients (group I) with brain death confirmed either by clinical assessment and EEG (17 patients) or...

متن کاملOrbital Doppler Sonography and Documentation of Brain Death
Multiparametric confirmatory tests for documentation of brain death were studied from a 24-year-old subject with clinically defined brain death after severe head injury. The importance of transorbital ultrasound Doppler sonographic measurements is discussed.
