Can Sclerotherapy Fight Venous Insufficiencies ?
How does sclerotherapy work?
Sclerotherapy hardens each vein using slight inflammation. During the injection of saline into the area, the affected veins occasionally experience short-term spasms in the leg muscles but disappear within a few minutes. Likewise, the patient, also in the short term, can feel a little warm. Further side effects are not present if the procedure is performed correctly.
After just a few days, the venous walls will grow together and later on (within a few weeks to several months) they are absorbed by the body. Once this occurs, they will then disappear (except for a few small connective tissues).
What are varicosities?
Varicose veins arise from venous vessels, which are responsible for returning the "spent" blood. In contrast to the arteries (blood transport from the heart to the organs and periphery), the veins are made up of a weak connective tissue and muscle sheath. They are, therefore, less resistant to pressure.
Varicosities are often caused by excessive pressure in the veins. Things that may cause venous insufficiencies:
Static loading of the legs when standing and sitting, forcing the veins in the knee and pelvic area to become stagnate
Accumulating thrombosis in the leg and pelvic area
Many similar stresses, usually in conjunction with congenital connective tissue weakness and the development of dilated veins, will cause varices to form. Due to an increased venous pressure or connective tissue weakness, a widening of the wall in the area may cause damage to a vein, The function of this valve, which retains the blood, is increased and the pressure on the next valve or vein increases. For example, instead of a force of 20 centimeters, the pressure suddenly rises to 40 centimeters of blood, etc.
Leg veins have venous valves about every 20 centimeters, all of which act like check valves. They transport the blood, in tandem, with the muscle pump to the heart (by movement of the muscles and joints, the blood-filled veins are compressed, which allows the blood to only flow towards the heart because of the non-return valves, meaning it is pumped upwards).
