Within angiology, the most common pathologies pertain to the veins (venous), and the medical branch exclusively dedicated to them is called phlebology.
The most common disorder within phlebology is venous insufficiency, which is when veins have trouble sending blood back from the limbs to the heart.
Depending on the severity, varicose veins are divided into four types:
- Grade I. Also called spider veins, they are characterised by being very fine and purplish in colour. They are usually a purely aesthetic problem, although they may sometimes cause the legs to feel heavy.
- Grade II. These are more visible and cause tiredness in the legs, tingling sensations, cramps, pain, and even the feeling of heat or itchiness.
- Grade III. The veins become more dilated and the symptoms more severe. The legs tend to swell and there may be a change in skin pigmentation.
- Grade IV. These are the most serious. Areas with ulcers and eczemas are very frequent.
