Varicose veins known as varicosity refers to a condition in which the veins of the leg become dilated & prominent. These veins look abnormally swollen, engorged, twisted and may be very painful. They appear dark blue or purple in colour. They tend to develop when blood flow in the veins slows down due to intrinsic defects of superficial veins or incompetent valves of the deep venous system of our legs which allows the backflow of blood into veins instead of pumping it to the heart.
Poor functioning of venous valves is the main cause of varicosity.
Obesity, prolonged standing, menopause, pregnancy, chronic constipation or even an abdominal tumour in rare cases also cause varicose veins.
Heredity is an important aspect in the development of Varicose Veins. Women with a family history of varicose veins are at higher risk of developing this disease than others.
Diet may be a factor, modern diet habits with a high content of fat and refined sugar with low fibre content may contribute to the development of the disease.
Varices increase in frequency with ageing as the veins lose their elasticity. But it may appear even in children.
Deep venous thrombosis or blood clots in the veins is also a cause.
Varicose veins may cause aching of the legs. The legs may feel heavy, tender or sore after standing for a prolonged time.
Varicose veins can become sore, itchy and inflamed, causing redness of the skin around them.
Some other symptoms include swelling, twisting or bulging in veins.
Prominent blue or dark purple blood vessels on thighs or calf muscles can be seen.
The irregular whitish patches on the ankles that look like scars, swollen ankles or skin shrinking above the ankles are also common things that indicate varicose veins. If veins become flaky, discoloured, ulcerated and prone to bleeding, consult a doctor for the best treatment of varicose veins.
Any condition in which proper blood flow is hindered has a risk of complications. The varicose veins may cause Bleeding, blood clots in the veins of the leg, which cause inflammation of the vein, varicose eczema, hard and tight skin.
While some other complications are venous ulcers around the ankles, which may cause skin discolouration and scars. Varicose veins may also be a symptom that indicates a risk of vein thrombosis or other circulatory system disorders. It is important to get varicose veins treatments before any complications occur.
Treating varicose veins is normally a very safe and simple process. According to the severity of varicose veins, there are several treatments including non-invasive and minimally invasive options available
Noninvasive Varicose Vein Treatments
Minimally Invasive Treatments
If you don’t show any improvement after conventional treatment or if your case is more severe from the beginning, then the following minimally invasive treatments are available
The treatment is done on the outside of your skin where a laser is used to send bursts of light energy at the vein causing it to fade or disappear. No surgery or incisions are required and this type of laser surgery can be used to treat small varicose veins close to the surface of the skin. This treatment doesn’t use needles or incisions. Laser treatments for varicose veins last for 15 to 20 minutes. Depending on the severity of the veins, two to five sessions are generally needed to remove spider veins in the legs.
Endovenous Laser Treatment (ELT)
This minimally invasive technique uses a catheter with a laser fibre inside that is passed into the vein. As the catheter is slowly retracted the laser heats up the vein, causing it to close up. This type of laser treatment is normally used to treat larger varicose veins in the leg.
Typically chosen to treat small varicose veins, sclerotherapy involves the injection of a solution/medicine into the veins that causes it to scar and close from the inside. The collapsed vein eventually fades as it gets absorbed into local tissue.
This procedure is the best option for larger varicose veins. Here, your doctor will insert a catheter into the vein, and radiofrequency energy (as opposed to laser energy for example) is used to heat up and collapse the vein, the aim of which is to seal the vein and make it disappear.
HIFU (high intensity focused ultrasound)is the latest in varicose veins treatment in Dubai.
It is a high precision Echotherapy solution for varicose veins and is the most progressive technology in the world for treating varicose veins and venous leg ulcers. Unlike endovenous laser, radiofrequency and even foam, this treatment is 100% non-invasive.
Basically, when using ultrasonic energy, a doctor can see the varicose vein that needs treating by using ultrasound. Using computer guidance, a beam of ultrasound can then be focused on the vein.
This beam of ultrasound travels through the skin and subcutaneous tissue. It doesn’t cause any damage whatsoever. The HIFU only generates heat at the focal point of the beam. Due to its precision individual varicose veins are treated without damaging any surrounding structures.
This technique includes stripping if the diseased vein in legs are really big with bigger veins leaking due to damaged valves.
