TCD EXAM WITH COMPLETE QUESTIONS WITH
ANSWERS 100% SOLVED
As you begin the TCD study, you know that various windows are used to insonate
specific intracranial vessels. Which of the following vessels would not be evaluated
through the transtemporal window? - ANSWER Basilar
The vessel that connects the left and right anterior cerebral arteries is the: - ANSWER
anterior communicating artery
The right and left basilar arteries join to form the vertebral artery. - ANSWER false
The posterior communicating arteries (PcoA) connect the anterior and posterior
circulation in the brain. - ANSWER true
what is a collateral pathway between ICA and ECA - ANSWER Ophthalmic artery
Which value is commonly used for evaluating intracranial vessels with TCD? - ANSWER
time averaged max mean velocity
________________ in children is a common reason for a TCD exam and can mimic the flow
changes in a vessel that would normally be seen in an adult with atherosclerosis. -
ANSWER sickle cell anemia
, What part of the brain do the MCA supply with blood? - ANSWER lateral portions of the
cerebral hemisphere
Which of the following becomes an extracranial to intracranial collateral route in the
presence of significant ICA disease? - ANSWER supraorbital and ophthalmic arteries via
ECA branches
The transorbital approach for transcranial Doppler is used to sudy the: - ANSWER carotid
siphon and opthalimic artery
A carotid duplex study documents an occlusion of the right ICA. Transcranial Doppler
(TCD) detects antegrade flow in the ipsilateral anterior cerebral artery (ACA). What is the
most likely source of blood flow in the right ACA? - ANSWER crossover collateralization
through the contralateral ICA and AcoA
A vasospasm can occur in the intracranial vessels - ANSWER after an aneurysm ruptures
Reversal of diastolic flow is one of the stages of impending brain death. - ANSWER true
For both the blind method and duplex method (color doppler) of transcranial doppler
you must angle correct to obtain the most accurate velocity measurement. - ANSWER
false
During intraoperative monitoring, the MCA is evaluated for _________________ that occur
when microemboli pass by the Doppler signal. - ANSWER micro embolic signals
