11/15/2023 0 Comments Ultrasound for varicose veinsTaking oestrogen-based contraceptive pills or hormone replacement therapy also appears to increase risk. Women seem to get varicose veins more than men, probably because of the hormone oestrogen. Susceptibility varies among cultures, although it's not clear if this is genetic or lifestyle-related (poor diet and lack of physical activity may be partly responsible). In Western nations it's estimated about 40% of people suffer from varicose veins, and it appears to be hereditary. Compressing, closing off or eliminating varicose veins improves circulation and relieves many of the symptoms. Varicose veins serve no useful purpose alternative pathways have already been formed to bypass the abnormal varicose veins and return blood to the heart. However, the severity of the symptoms isn't always related to the appearance of the veins, and even large, obvious ones may cause little or no discomfort. Not all varicosities are caused by problems in the saphenous or perforating veins though any superficial leg vein can become varicose, although these lesser veins are usually quite small and cause few symptoms. The veins near the surface, however, have very little support overall. Deeper veins, which lie within and between muscles, aren't affected in the same way, because muscular contraction (when walking and so on) compresses the veins, creating a pumping action that returns blood to the heart and provides support. When the blood flows backwards because of weak valves, it's known as reflux. Weak vein walls also make the problem worse. When one or more valves fail, blood can pool in the section, causing the bulgy, tortuous appearance of varicose veins. In the legs – the most common site of varicose veins – these valves are particularly important because the blood is flowing against gravity. One-way valves in veins direct the flow of blood back to the heart. Most varicosities are a result of problems with the main superficial, or saphenous, veins that collect blood from other surface veins. There are two venous systems in our legs – deep veins and superficial veins – which are connected by smaller perforator veins. In this article we explain what varicose veins are, who gets them, and what treatment options are available, as well as management strategies to help reduce discomfort. One of the newer treatments on the market is endovenous laser therapy – a less invasive alternative to surgery performed by experienced and skilled practitioners, with good success rates reported Many forms of treatments exist to suit individual cases, personal preferences and budgets. Serious complications can develop over time too, such as phlebitis (vein inflammation), blood clots, dermatitis and painful vein ulcers that, in extreme cases, can lead to amputation. They can also cause a fair amount of pain and discomfort on a daily basis, with some of the more persistent symptoms including swelling, throbbing and leg cramps.
