Additional Diagnosis of Brain Death by Transcranial Doppler

Ever since transplant surgery became a common procedure. The early diagnosis of irreversible cessation of cerebral function has become an important need We analysed the findings of transcranial doppler of five cases. Two was diagnosed brain death by currently accepted criteria. Two cases showed absence of intracranial blood flow and normal to disturbed flow status of the cervical carotid artery. Three cases showed reverberating flow pattern with reflux phenomenon. Transcranial doppler investigation seems to provide a practical, non-invasive. And reliable disgnostic evidence for the arrest of cerebral circulation.
