Estimation of Brain Death Using Transcranial Doppler Sonography
Takuo HASHIMOTO, M.D.,Toshinori KANKI,M.D.,Satoshi ABE, M.D. Norio NAKAMURA, M.D. Department. of Neurosurgery, The Jikei University School of Medicine (Received 4 September 1989, Accepted 10 January 1990) Abstract Flow patterns of the velocity measured by transcranial Doppler(TCD) were compared with the changes of intracranial pressure(ICP) in patient with subarachnoid hemorrhage and severe hea...
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 کاملDiagnosis 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 کاملTranscranial Doppler sonography in patients with severe brain injury.
To the Editor: We read with interest the article by Wang et al1 regarding the use of transcranial Doppler sonography to assess middle cerebral artery flow parameters in patients with serious brain injury. The importance of developing noninvasive techniques to monitor intracranial pressure in patients at risk of developing raised intracranial pressure remains challenging, but if achieved, they h...
