Introduction: . Chronic venous disease (CVD) is due to incompetent superficial veins (ISVs) of legs. In which 45-75% are related to Great saphenous vein (GSV)incompetency and 15-25% are due to Short saphenous vein (SSV) incompetency. Objectives of this study was to study the anthropometric measurements and the diameter and incompetency of GSV and SSV in CVD patients and its relation with venous clinical severity score (VCSS). Methods: In this cross sectional study Patients of primary CVD (diagnosed clinically and on Duplex doppler USG )on 200 legs were enrolled. Anthropometric data, and findings on duplex USG and VCSS were noted and analysed. Results: The mean age, weight (kg), height (cm), hip diameter (cm), waist diameter (cm), and BMI (kg/m2)of the patients were 35.65±9.91, 75.41±12.34, 63.48±5.06, 40.80±3.49, 40.09±4.35, and 29.37±6.97 respectively. The percentages of male and female were 82.00% and 18.00%,. The mean VCSS, Diameter (in mm) of GSV just below SFJ , upper thigh ,mid-thigh , above knee , below knee , Mid leg , medial malleolus , SSV Diameter Just below knee , mid-calf and at Malleolus were 10.40±2.54, 9.09±2.04, 8.10±1.96, 7.13±1.93, 6.28±1.89, 6.81±1.77, 6.61±1.88, 4.79±4.13, 3.93±0.75, 4.47±5.84, and 3.85±2.86. Conclusion: Diameter of GSV and SSV were not significantly correlated with age, weight and BMI. Also, the hip , waist circumference, and hip-to-waist ratio were not significantly associated. Moreover, the Saphenofemoral and saphenopopliteal Junction and perforator incompetency and GSV diameter were significantly positively correlated with VCSS.
