Volume 47, Issue 4 December 2023 JVU 474-193 | Screening for Subclavian Artery Stenosis
JVU 474-193 | Screening for Subclavian Artery Stenosis
December 2023 Journal for Vascular Ultrasound

This issue contains a review on cerebral vasomotor reactivity testing using transcranial Doppler in COVID patients, a review on the decrease in endothelial function in peripheral arteries and the influence of aging, a review on screening for subclavian artery stenosis, and a report on catheter misplacement following subclavian vein catheterization.



After reading and studying the papers used for CME in the December 2023 Issue of the Journal for Vascular Ultrasound, participants will be able to:

  1. Describe the usefulness of using transcranial Doppler when monitoring the middle cerebral artery.  
  1. State the transducer frequency used to interrogate the middle cerebral artery. 
  1. State the anatomic or acoustic window used to assess the middle cerebral artery with transcranial Doppler.  
  1. Explain the gas mixture used to provoke the left middle cerebral artery. 
  1. List the risk factors affecting endothelial function. 
  1. State which disease is the leading cause of mortality and morbidity.  
  1. List the conditions where arteries may stiffen.  
  1. State the most common noninvasive modality used to evaluate the degree of endothelium dependent vasodilation.  
  1. List the ultrasound characteristics associated with subclavian artery stenosis.  
  1. Describe how hand acceleration time is measured. 
  1. List the symptoms associated with subclavian artery stenosis.  
  1. State the most common malposition of a subclavian vein catheter.  
  1. Explain the normal course of the guidewire from the right subclavian vein to the right atrium.  
  1. State the incidence of subclavian vein catheter malposition.
