Objectives: After studying the article titled “A Study on First Ischemic Stroke Patients for Prevalence of Extracranial Carotid Artery Stenosis and Risk Factors: Our Experience in Northeast India and Review of Literature,” you will be able to:
Evaluate the results of a study performed to assess the prevalence of carotid artery stenosis and risk factors in stroke patients of northeast India
Compare the prevalence of significant extracranial carotid artery stenosis between different ethnic groups
Compare the prevalence of intracranial artery stenosis versus extracranial artery stenosis between different ethnic groups
In this study, what angle of insonation was used in the carotid Doppler study? 0° 30° 60° 90°
In this study, what minimum value is considered indicative of intima/media thickening? 0.1 mm 0.3 mm 0.6 mm 0.9 mm
In this study, a stenosis of ≥50% is considered: Normal Minimal Significant Severe
What minimum PSV was used to indicate severe stenosis? 40 cm/s 100 cm/s 140 cm/s 230 cm/s
Which plaque type is predominately echolucent? Type I Type II Type III Type IV
According to Table 1, how many patients had a complete occlusion? 2 3 9 14
Which ultrasound parameter is helpful to visualize hypoechoic plaques which are difficult to visualize with gray scale imaging? CW Doppler Color Doppler Power Doppler Pulsed Doppler
According to Table 2, how many males had significant stenosis? 2 12 46 111
According to Table 7, what percentage of Caucasians had concomitant intracranial stenosis and extracranial stenosis? 34.2% 39% 42% 56.3%
According to Table 7, what percentage of Northeast Indians had concomitant intracranial stenosis and extracranial stenosis? 33.3% 34.2% 39% 42%
