| Summary: | Introduction: Colour Doppler ultrasonography plays an important role in determining the morphological and hemodynamic information of the venous system. This study aimed to find out the prevalence of increased great saphenous vein diameter at the level of the knee among patients with varicose veins in a tertiary care centre.
Methods: A descriptive cross-sectional study was carried out in the Department of Radiology at a tertiary care centre from 30 October 2021 to 31 March 2022 after taking ethical approval from the Institutional Review Committee (Reference number: 028-077/078). A convenience sampling technique was used for the study. The study group consisted of patients over 18 years, coming for ultrasonography examination of the lower limb with the clinical symptoms and signs of varicose veins. The great saphenous vein diameter was measured at the level of the medial femoral condyle of the knee using the software in the ultrasonography unit. B mode, colour Doppler and spectral analysis were done. A cut-off value of 5 mm for the diameter of the great saphenous vein was taken to indicate the presence or absence of varicosity and saphenofemoral reflux. Point estimate and 90% Confidence Interval were calculated.
Results: Among 72 patients with varicose veins, the diameter of the great saphenous vein was increased in 59 (81.94%) (74.50-89.38, 90% Confidence Interval) patients.
Conclusions: The mean diameter of the great saphenous vein in our study was similar when compared to other studies conducted in similar settings.
