JVU 473-119 | Effect of Internal Carotid Artery Doppler Peak-Systolic Velocity Thresholds for Classifying Ipsilateral Ischemic Stroke Due to Large Artery Atherosclerosis According to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) System
September 2023 Journal for Vascular Ultrasound
OVERVIEW
This issue contains a review on the effects of internal carotid artery Doppler peak systolic velocity thresholds for classifying ischemic stroke, a review on color M-mode ultrasound to assess carotid arteries, a research article that compares Doppler and oscillometric methods of assessing an ankle-brachial index in premenopausal women, a case report that reviews the identification of an undiagnosed popliteal artery aneurysm with intravascular ultrasound (IVUS) in the setting of acute limb ischemia and a review on continuous transcranial Doppler during treatment for intracranial pressure.
LEARNING OBJECTIVES
After reading and studying the papers used for CME in the September 2023 Issue of the Journal for Vascular Ultrasound, participants will be able to:
1. List the major categories of stroke classifications based on Trial of Org 10172 in Acute Stroke Treatment (TOAST) System
2. State which interventions are used to treat patients with significant carotid artery disease.
3. Define a transient ischemic attack.
4. List a patient’s 10-year atherosclerotic cardiovascular disease (ASCVD) risk score.
5. Describe the ultrasound parameters used to screen for cardiovascular risks.
6. Compare how the common carotid artery distensibility decreases in the senior age group to the middle and younger age groups.
7. Describe how an ankle-brachial index is calculated as a ratio.
8. State the recommended ankle-brachial index cut-off for diagnosing peripheral arterial disease.
9. List various intermittent claudication symptoms.
10. Explain the various uses of intravascular ultrasound (IVUS).
11. State the diagnostic examinations typically used to evaluate an arterial aneurysm.
12. Explain the benefits of IVUS.
13. State the depth used when evaluating the middle cerebral arteries with continuous transcranial Doppler.
14. Explain why the pulsatility index increased while the mean flow decreased in response to systemic hypotension.
15. State how long after the initiation of therapy for intracranial pressure did the mean flow velocities and pulsatility index stabilize and appear normal.
