Veins carry deoxygenated blood from the tissues back to the heart. The flow in the veins is maintained by a series of valves which allow flow only towards the heart, i.e. - one-way traffic. When the valve gets damaged blood stagnates in the vein leading to varicose veins.
Varicose veins are dilated and can be close to the surface or deep within the legs. Those close to the surface can become long and coiled like a snake. It often occurs in those who stand for long hours, like policemen, waiters, salesmen and teachers. It is more common in women and usually starts during pregnancy. In many, the varicosities regress after delivery but with recurrent pregnancies the veins may get permanently dilated.
Stagnation of blood can be prevented by Medical management
Color Doppler study helps to determine which system of vein, deep or superficial, is affected. It helps to decide on the mode of treatment.
Some varicose veins can be managed by injecting sclerosing solution into the vein to help them close.
SURGICAL TREATMENT
Surgical treatment is needed if non-surgical measures fail to control or if there are complications. In open surgery the damaged veins are removed through small incisions. Recently less invasive procedures like Laser and RF ablation have become more popular and have shown good results. In cases of laser and RF ablation, no cuts are made. The laser or RF fibre is passed into the vein through a tiny needle hole and the veins are burnt by the heat generated. All veins cannot be removed or destroyed by surgical means. Even after surgery patient must wear compression stockings for 4-5 months to get maximum benefit.
