Have you ever watched someone wondering why they have green stripes on their legs? Well, these stripes and these scribbles are the signs of varicose veins. Sometimes they are not very visible, but they can be very disfiguring and sometimes uncomfortable. They most often occur in the legs, but can also occur in other parts of the body. Varicose veins are swollen veins due to weakness or damage.
To understand what causes this condition, you need information about the veins in general. The veins have many valves through which blood can flow in the right direction. These valves can easily be thought of as small blockages that prevent blood from accumulating after passage. If these valves are damaged, blood will collect in the vein and cause varicose veins. The reason that varicose veins appear on the legs and ankles is because they are the most distant parts of the body. Over time, these veins wear out more easily and are usually the first swollen and blocked.
Symptoms of varicose veins include swelling of the feet and ankles, a strong feeling in the legs, fatigue and pain after long periods of sitting or standing, itching in a certain area and changes in skin color . usually a greenish gray or brown color in the affected area.
It is quite easy to tell if a person has varicose veins. A doctor can simply test where the patient is on his back and lift his leg up in the air until it is at a 45-degree angle until the veins are deflated, then lower immediately. If a person has varicose veins, they appear as soon as blood comes back to that area.
There are many treatments for varicose veins. The treatment discussed here is occlusive treatment. The occlusion treatment was approved by the Food and Drug Administration (FDA) in March 1999 and received very high marks. With this special treatment, a small catheter is inserted through a small skin puncture into the damaged vein. The occlusion catheter supplies the venous wall with high frequency energy, which causes the vein to narrow and close. Once this vein is closed, the neighboring healthy veins restore normal venous blood flow to the legs. When normal blood flow returns, symptoms are usually reduced.
