The purpose of this study was to invenstigate the distibution of vein incompetence and the nature of venous haemodynamics accompanying the development of lower extremity primary varicose veins (LEPVV). The entire venous circulation of 219 lower extremities in 165 patients (pts) with LEPVV was evaluated, by using Duplex colour ultrasonography. The greater and lesser saphenopopliteal junction, and perforating veins. Demonstration of bidirectional flow signified venous incompetence. Quantitation of venous reflux was estimated after manual calf compression with pts in a standing position. All the symptomatic legs had branch venous incompetence. Quantitation of venous reflux was estimated after manual calf compression with pts in a standing positiion. All the symptomatic legs had branch venous disease,, 61% had GSV incompetence, 4% had LSV incompetence, 12% showed concurrent GSV and LSV incompetence, while 23% demonstrated no evidence of GSV, and LSV disease. Twenty five per cent and 62% of the symptomatic legs demonstrated deep and perforating vein incompetence, respectively. Furthermore, 28% of the asymptomatic lower extremities had insufficiency of saphenofemoral (27 pts) and saphenopopliteal (4 pts) junction. The median peak venous reflux in the incompetent GSV was 0.72 ml/s (range 0.2 to 2.5 ml/s). The peak venous reflux in the incompetent popliteal vein (two cases), in the case of concurrent common femoral and superficial femoral vein incompetence, was 8 ml/s. In conclusion, the observed heterogeneity in pts with LEPVV support the hypothesis tha this condition is probably a part of another entity that might be called "lower extremity venous insufficincy" whose treatment should be highly individualised. To this end, Doppler imaging can help.
