Role of transcranial Doppler in neurocritical care.
Transcranial Doppler has several practical applications in neurocritical care. It has its main application in the diagnosis and monitoring of vasospasm in patients with subarachnoid hemorrhage. In addition, it holds promise for the detection of critical elevations of intracranial pressure. Its ability to measure CO2 reactivity and autoregulation may ultimately allow intensivists to optimize cer...
متن کاملNeurological improvement after cranioplasty - analysis by transcranial doppler ultrasonography.
Cranioplasty can improve neurological status in patients with skull bone defects. The mechanism of postoperative improvement in neurologic status might be increased cerebral blood flow (CBF) velocity due to elimination of the effects of atmospheric pressure. Between May 2001 and June 2002, 13 patients (8 men and 5 women; average age, 46 years; range, 21-65 years) were studied. Postoperative cha...
متن کاملRole of transcranial Doppler ultrasonography in stroke.
Transcranial Doppler sonography is a non-invasive, non-ionising, inexpensive, portable and safe technique that uses a pulsed Doppler transducer for assessment of intracerebral blood flow. This article deals with the principles and technique of transcranial Doppler sonography. It gives a brief overview of its use in evaluation of intracranial steno-occlusive disease, subarachnoid haemorrhage, an...
متن کاملThe Findings of Transcranial Doppler Ultrasonography in Patients with Ischemic Stroke
Background: Stroke is a multifactorial disorder, the most common cause being arterial occlusion. Transcranial Doppler Ultrasonography (TCD) is a common non-invasive method available for assessment the arterial blood flow of the brain. Objective: Assessment the hemodynamic parameters of cerebral arteries, using TCD device in patients suffering ischemic stroke. Materials and Methods: This descr...
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...
