The purpose of this study was to elucidate frequency and normal size of soleal vein groups.
The subjects were 52 lower limbs of 40 persons who were diagnosed to be competent veins without thrombus and arteries with normal Doppler flow pattern by ultrasonography. The detection rate of the vein size more than 2 mm in diameter was 40% in proximal vein, 100% in central vein, 42% in medical vein, 27% in lateral vein, 27% in distal medial vein, and 10% in distal lateral vein. The detection rate of the vein size in maximum diameter was 0% in proximal vein, 90% in central vein, 6% in medial vein, 2% in lateral vein, 2% in distal medial vein, and 0% in distal lateral vein. The mean diameter of central vein was 6.7±1.8 mm, so that the upper limit became 10.3 mm if the normal range was double of standard deviation.
In conclusion, since the central vein is the most frequent and maximal among the soleal vein groups, it is suitable that the normal size of soleal vein is 10 mm ≥ in diameter.
