Objectives: After studying the article entitled “The Relationship Between Posterior Communicating Artery Formation and Vertebral Artery Flow Parameters,” you will be able to
Understand the pathology of vertebrobasilar insufficiency (VBI)
Describe the diagnostic testing methods available
Understand the significance of collateral circulation
According to the article, what is the most significant symptom of VBI? Decreased level of consciousness Headache Vertigo Vision loss
A total of 102 patients younger than 50 years were referred for magnetic resonance angiography to evaluate the following: The patient’s headache The presence of trauma To rule out tumors To measure posterior communicating artery diameter
Which of the following is the gold standard diagnostic method for demonstrating collaterals? Carotid duplex sonography Transcranial Doppler Computerized tomography Angiography
The vertebral artery flow volume is an important parameter to show the following: The diameter of the vertebral artery Perfusion in posterior circulation The cause of the patient’s symptoms The likelihood of successful treatment
What is a possible benefit of the presence of intracranial collaterals such as the circle of Willis? There is no noticeable benefit It can protect the brain against infarcts It can diminish the frequency of headaches It negates the need for any further intervention
