如何分辨正常明顯的血管還是靜脈曲張? How to differentiate apparent normal veins and varicose veins?

Updated: Nov 18, 2017


Some apparent veins of our legs are frequently misunderstood as abnormal spider veins or varicose veins. The most common ones are tiny thread veins, greenish bulging veins, dorsal foot veins, ankle saphenous veins, etc. 

一、紅色細血絲 (Tiny thread vein)


1. Tiny thread veins

These numerous veins diffusely distribute over the legs with diameters ranging between 0.1mm-0.2mm (Figure 1). These veins are the ordinary veins in our skin, most in the epidermal layer. They can be dilated and become apparent under the influence of food (alcohol), drug (vasodilator, contraceptives), female hormone, standing for a long time, high temperature (hot weather), emotion. These veins do not need treatment. Forceful clearance of them may stimulate growth of other new vessels. With detailed observation, the real abnormal spider veins look different from them. The spider veins appear tortuous with deep color and tend to be in clusters (Figure 2).
