Varicose veins: What are they?
Varicose veins are usually blue or purple in colour and can appear like ropes under the skin.
They are always more prominent in hot weather, and after long periods of standing or exercise, but varicose veins tend to reduce in size with leg rest and elevation.
Minimally invasive treatments are now recognised by vein experts around the world as the treatment of choice. These alternatives to vein surgery are becoming the new “standard of care” to remove varicose veins.
Varicose veins and underlying causes
In most cases, varicose veins represent the distended tributaries or “branches”, coming off larger malfunctioning veins (“trunks”). They are most common in the calves, but can be seen anywhere in the lower leg, depending on what “feeder vein” is malfunctioning.
Varicose veins are always a sign of Venous Reflux, or Venous Insufficiency.
Each vein has small unidirectional valves, and they regulate the blood flow towards your heart. When your calf muscle contracts, the valves in your veins open. This is what allows the blood to flow upwards, towards the heart. Each time the muscles relax, blood “falls” back toward the feet (helped by gravity). The valves quickly close, to stop blood from flowing away from the heart.
When the valves don’t close properly, we call it venous reflux (also venous insufficiency or venous incompetence). Blood flows in the wrong direction, and this may cause the blood to pool in the leg, as it is not effectively returned to the heart. This then causes progressive dilatation of the veins, leading to the formation of varicose veins.
The best varicose vein treatment is not to simply remove them surgically (as some clinics do), but to eliminate the underlying source of reflux first.
