- Blue/red spider veins up to 1 mm.
- Varicose veins from 1 to 5 mm (collateral, reticular and perforating veins).
- Saphena Magna.
Varicose veins are the large, visible and bulging leg veins, felt under the skin. They arise due to weakness of the vein wall, because the valves no longer work. Under the pressure of gravity, these veins can continue to expand. The veins may become longer, twisted, pouched, thicker and painful.
- Heavy lifting.
- Warm climate.
- Increasing age.
- Multiple pregnancies.
- Prolonged standing (or sitting).
- Female gender.
- Prior blood clots in superficial or deep veins.
- Ankle and leg swelling.
- Heaviness and fullness in the legs.
If you experience any of these symptoms, contact an expert. Do not ignore leg pains!
Our veins return blood from the arms and legs to the heart. Because veins work against the force of gravity in legs, they have valves that allow forward blood flow, but not reverse. Contraction (squeezing) of the leg muscles pumps the blood towards the heart while the valves in the veins prevent backflow towards the feet. If these valves lose their function, the blood leaks (reflux) toward feet, accumulates in thin-walled superficial veins causing them to enlarge and become what we call ‘’varicose veins’’.
Varicose veins are generally seen during physical examination with naked eye, since they are close to the skin surface. However, the vein with nonfunctioning valves that create varicose veins are generally more deeply located, and thus cannot be seen without special instruments. These veins can be readily seen with a color or duplex Doppler ultrasound machine. Ultrasound examination however, must be performed by an experienced radiologist, preferably by the one who will also perform the treatment.
The principle of thermocoagulation is the heating of the vein which makes the vein coagulate. This rise in temperature is achieved by sending a high frequency pulse in the tip of the needle or catheter. Because the needle or catheter is isolated, the effect is very local and the effect on the surrounding tissue is limited.
- The small veins are treated with the special designed thermo coagulation needles R3I and R6I for veins on face or legs.
- The larger veins up to 5 mm are treated with a special designed catheter which will be penetrated into the vein and coagulates the vein from the inside.
- The Saphena Magna is treated with a CR45i catheter.
