Background: Varicose veins are veins that have become dilated and tortuous. The term commonly refers to the veins on the leg, although varicose veins can occur elsewhere. When veins become varicose, the leaflets of the valves no longer meet properly, and the valves do not work (valvular incompetence). Colour flow duplex ultrasound scan has as the gold standard imaging modality for venous disease. As conventional surgery is minimized due to cosmetic purpose the lower recurrence and fewer complications. This study is performed to clinically evaluate the cases of varicose veins of the lower limb and to evaluate varicose vein in lower limb by Duplex scan. Materials and Methods: Patients with varicose veins admitted in Department of CTVS & Surgical wards of our Medical College fitting in inclusion and exclusion criteria were taken. A detailed clinical examination was done. Duplex scan (colour Doppler) study of lower limb venous system. Results: In this study, most of the patients were having anatomically involvement of superficial veins + perforators in 29 patients (69.05%) and only superficial veins in 13 patients (30.95%). Out of 42 patients who underwent colour doppler, 25 patients (59.5%) found unilateral saphenofemoral incompetence + perforator incompetence. Conclusion: Surgically management like Saphenofemoral flush ligation with stripping of veins was most common procedure, tredelenberg operation with multiple ligation of veins, radiofrequency ablation, sclerotherapy and conservative management like compression hosiery, elastic bandage therapy were most commonly performed in our hospital with satisfactory results. In these procedures have minimum recurrence rate and complication were found.
