Superficial veins, deep veins and communicating veins are the three types of veins located throughout your legs. These venous systems all work together to carry blood back to the heart.
Superficial veins, which are closest to the skin and are the veins easily seen, carry ten to fifteen % of the blood back to your heart. These veins are connected using the communicating veins to the deep veins.
The deep veins are located deep within the muscles of your leg (which help pump the blood back to the heart) and carry eighty-five to ninety % of the blood.
Sometimes if the vein wall is weakened or injured, the blood flow becomes incompetent and can begin flow in a backward manner when the muscles are relaxed. This can cause numerous problems including stretching and twisting of the veins, swelling, lethargic blood flow which increases the possibility of a blood clot forming. Over some time, these problems can progress into more severe conditions such as varicose veins, deep vein thrombosis, or oedema.
When to use varicose veins treatment?
When you are standing, the blood through your veins is pumped upwards using the muscles of your calves and thighs. These muscles push the blood upwards back to the heart in a smooth motion. When these muscles are relaxed, the blood would rush back down into the lower extremities dobrze. The valves in the veins prevent this from happening and can often be heard as a “whoosh” sound when holding a hand-held Doppler to the venous system. If all is going correctly, the “whooshing” sound will be followed by silence as the valves stop the blood flow until the next contraction of the calf muscle. When these valves are not working properly they can cause congenital abnormalities of the veins, deep vein thrombosis, and varicose veins.
Preventing these problems from occurring in the first place can be easily done by walking to allow the blood to flow as normally as possible. When it is too late, and problems have already arisen, the next step will be to get treatment by a skilled medical practitioner.
Treatment usually depends on the severity of the problem. Using diagnostic tests, such as the Doppler and ultrasounds, the doctor will be able to easily locate where the problem is and begin proper treatment. Deep vein thrombosis would normally be treated with medication that may prevent a clot from becoming dangerous. These drugs do not necessarily dissolve the clot. Varicose veins in legs can be treated with surgery, special stockings or injections.
