Key result
The ratio of peak systolic velocity of the internal and common carotid arteries strongly correlated with the severity of carotid artery stenosis.
Why the study?
Relatively little data were available to indicate how precisely peak systolic frequency correlates with luminal narrowing and how to clinically gauge stenotic lesions with frequency spectrum analysis.
Does the ratio of peak systolic velocity of internal and common carotid arteries correlate with the severity of carotid artery stenosis in patients referred for carotid Doppler evaluation?
Cross-Sectional (n=123)
No
Does the ratio of peak systolic velocity of internal and common carotid arteries correlate with the severity of carotid artery stenosis in patients referred for carotid Doppler evaluation?
The ratio of peak systolic velocity of the internal to common carotid artery significantly correlates with carotid artery stenosis severity, supporting its utility in Doppler sonography evaluation.

Introduction: Doppler Sonography has become an accepted method for clinical detection and evaluation of cervical carotid occlusive disease. One of the most important parameters used in doppler assessment of carotid stenosis is the peak Doppler shift frequency occurring during systole. However, relatively little data is available to indicate how precisely peak systolic frequency correlates with luminal narrowing and how peak systolic frequency measurements made with frequency spectrum analysis should be used clinically in gauging stenotic lesions. Aim: To assess the ratio between peak systolic velocity of internal and common carotid arteries and its significance in prediction of carotid artery stenosis. Materials and Methods: This is a cross-sectional analytical study performed on patients who are referred to department of Radiodiagnosis, Sree Mookambika Institute of Medical Sciences (SMIMS), Kulasekharam for carotid artery ultrasonography colour doppler evaluation. Conclusion: Doppler Sonography plays an important role in the early detection and management of carotid artery stenosis disease. The increased ratio of peak systolic velocity of internal and external carotid arteries is correlating with the detection of carotid artery stenosis, thereby improving sensitivity and specificity

S et al. (2022) conducted a cross-sectional in Carotid artery stenosis (n=123). Ratio of peak systolic velocity of internal carotid artery and common carotid artery was evaluated on Correlation between the ratio of peak systolic velocity of internal and common carotid artery and severity of carotid artery stenosis (Pearson's r 0.46 (right) and 0.56 (left), p=0.00). The ratio of peak systolic velocity of the internal and common carotid arteries strongly correlated with the severity of carotid artery stenosis.
