Assessment of Carotid Artery Stenosis Using Doppler Ultrasonography: A Cross-Sectional Study in High-Risk Patients
Abstract: Background: Carotid artery stenosis (CAS) is a significant cause of ischemic stroke and transient ischemic attacks (TIA). Early detection, especially in high-risk populations, allows timely intervention and can reduce morbidity and mortality. Doppler ultrasonography is a non-invasive, real-time imaging modality widely used for screening and assessment of CAS. Objectives: To determine the prevalence and severity of carotid artery stenosis in a high-risk patient population using Doppler ultrasonography. Methods: A descriptive, cross-sectional study conducted over 6 months at Dr. Vithalrao Vikhe Patil Foundation Medical College and Hospital involving 20 high-risk patients (age ≥ 40 years) with risk factors such as hypertension, diabetes mellitus, smoking, dyslipidemia, and previous history of cerebrovascular events. Doppler ultrasonography measured intima-media thickness (IMT), peak systolic velocity (PSV), end-diastolic velocity (EDV), and plaque morphology to categorize the degree of stenosis. Results: Of the 20 patients, 15 (75%) were male and 5 (25%) female. The mean age was 62.3 ± 9.8 years. Doppler detected CAS in 10 patients (50%) with varying severity: mild (n=6), moderate (n=3), and severe (n=1). Increased carotid IMT correlated positively with severity of stenosis (p
