Doppler study of left lower limb venous system. Deep venous system. Left common iliac, internal and external iliac, common femoral, superficial Femoral, popliteal and tibial veins show normal flow pattern, physic variation and compressibility. Spectral changes after Valsalva maneuver and distal augmentation suggest no definite thrombus proximal or distal to examined veins. Normal intraluminal echoes seen. No evidence of thrombosis is seen. Superficial venous system. Sapheno-femoral and soybean-popliteal junctions show normal flow direction. Long saphenous vein appears normal and shows normal flow. No evidence of varicose veins is seen. Perforators are patent and competent. Impression:- ?Normal deep and superficial venous system or left lower limb. ?No evidence of deep vein thrombosis is seen. ?No evidence of varicose vein is noted. ?Subcutaneous edema seen in lower leg and foot. What does the above report suggest? What would have been the reason for L leg lower limb venous system? What further investigations should be done? She is 24 and working in I.T. Office for about 6 to 8 hours. Can it be fileria? Kindly advise what to do further in this problem?
