Transcranial Doppler ultrasonography: From methodology to major clinical applications

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...

transcranial doppler ultrasonography in beta-thalassemia major patients without and with thrombocytosis

conclusion following splenectomy, thrombocytosis can predispose the patients to an increase in cerebral blood velocities more than respected with anemia. but by transcranial doppler ultrasonography no evidence of significant stenosis were found in intracerebral arteries to conclude that the beta-thalassemia major patients were more prone to the development of stroke secondary to this abnormalit...

Transcranial Doppler Ultrasonography in Beta-thalassemia Major Patients Without and With Thrombocytosis

BACKGROUND Beta-thalassemia is a type of anemia in which the patients may require splenectomy and this can lead to thrombocytosis with increased risk of stroke. Transcranial Doppler ultrasound is a method for determining cerebral vessel stenosis. OBJECTIVES The aim of this study was to investigate whether the risk of a future stroke secondary to cerebral artery stenosis can be predicted with ...

The 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...
