Role 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 کاملCerebral monitoring during carotid endarterectomy by transcranial Doppler ultrasonography
PURPOSE To evaluate the efficacy and safety of cerebral monitoring by transcranial Doppler ultrasonography (TCD) for the detection of cerebral ischemia during carotid endarterectomy (CEA). METHODS From August 2004 to December 2013, 159 CEAs were performed in a tertiary hospital. All procedures were performed under general anesthesia. Intraoperative TCD was routinely used to detect cerebral is...
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...
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...
