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 کاملGreater occipital nerve block by using transcranial Doppler ultrasonography.
Greater occipital nerve block (GONB) is a common procedure to diagnose and treat patients with occipital neuralgia and to differentiate headaches of cervical origin from other types of headaches (1,2). Although a relatively safe method and easy to perform, the classical method of blind injection just medial to the palpated occipital artery at the level of the superior nuchal line is not target ...
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 detection of anterior cerebral artery vasospasm.
The performance of transcranial Doppler in the detection of anterior cerebral artery vasospasm and vasospasm in patients after subarachnoid haemorrhage was analysed. Transcranial Doppler and cerebral angiography were performed within the same 24 hours on each of 41 patients with acute subarachnoid haemorrhage. Sensitivity and specificity of transcranial Doppler to classify middle cerebral arter...
متن کاملTranscranial Doppler detection of vertebrobasilar vasospasm following subarachnoid hemorrhage.
BACKGROUND AND PURPOSE Transcranial Doppler sonography is of established value in the detection and monitoring of middle cerebral artery vasospasm. Little information exists on the utility of transcranial Doppler for detection of posterior circulation vasospasm. METHODS Cerebral angiography and conventional hand-held transcranial Doppler sonography were compared to determine sensitivity and s...
