Noninvasive estimation of cerebral perfusion pressure with transcranial Doppler ultrasonography in traumatic brain injury.
AIM In traumatic brain injury (TBI) patients, to overcome the secondary insults, cerebral perfusion pressure (CPP) oriented therapy is recommended. The study is assigned to estimate CPP values with middle cerebral artery (MCA) flow velocities measured noninvasively using transcranial Doppler ultrasonography (TCD). MATERIAL AND METHODS Forty-seven TBI patients were studied. Intracranial pressu...
متن کاملCerebral Perfusion Pressure Based Management of Traumatic Brain Injury
Cerebral perfusion pressure (CPP) is the difference between mean arterial pressure (MAP) and intracranial pressure (ICP). Traditionally, management of traumatic brain injury (TBI) depended mainly on ICP control strategies. Based on the evidence that cerebral ischemia plays a major role in causing poor neurological outcome in traumatic brain injury (TBI) and cerebral blood flow autoregulation is...

15 صفحه اولRole of transcranial Doppler in traumatic brain injury.
I agree that one of the important causes of neurological deterioration in patients with TBI is the increase in ICP secondary to cerebral edema (4). An elevated ICP hampers the cerebral perfusion and these dynamic changes can be evaluated in real time by proportionate reduction in blood flow velocities and PI on TCD (2). Thus, TCD can provide important information about ICP and help in early ide...
متن کاملTranscranial Doppler Ultrasonography in Patient With Tight Right Middle Cerebral
Ultrasound examination of the extracranial carotid and vertebral arteries has been used for many years to diagnose and manage patients with cerebrovascular disease. However, evaluation of the intracranial circulation has until now required angiography. Extracranial ultrasound examinations utilize probe frequencies ranging from 3 to 10 MHz. These frequencies are unable to penetrate bone sufficie...
