ROLE OF TRANSCRANIAL DOPPLER IN ADULT PATIENTS WITH CEREBROVASCULAR INSULTS
Maged Mohamed Sabry;
Abstract
TCD can be aptly called as the doctor’s stethoscope of the brain. Since its introduction in 1982, by Rune Aaslid, TCD has evolved as a diagnostic and monitoring tool. Currently, TCD is the only diagnostic tool that can provide real time information about cerebral hemodynamics and can detect embolization to the cerebral vessels.
TCD, unlike other cross sectional imaging, is a noninvasive, cost-effective, and bedside tool for obtaining information regarding the collateral flow across various branches of the circle of Willis in patients with cerebrovascular insult.
Power mode Doppler TCD is valid compared with CTA for the diagnosis of arterial occlusions in patients with acute ischemic stroke, especially in the MCA, and can be implemented in many ERs that have less access to CTA or MRA.
As regards vasospasm following SAH, Transcranial Doppler ultrasonography assists in the clinical decision-making regarding further diagnostic evaluation and therapeutic interventions
Transcranial Doppler ultrasonography enables noninvasive monitoring of raised intracranial pressure which may be secondary to cerebrovascular insults.
It should be recognized that, as with any ultrasound technique, what may look easy to the unschooled observer is not; There are numerous pitfalls and tricks for obtaining good results, which only come with practice
