Varicose Veins Q & A
What Causes Varicose Veins?
Varicose veins are the result of poor blood flow in the legs. As the blood circulates, it must be forced upwards against gravity to make its way back to the heart. If a person is overweight or has poor muscle tone, it can be extremely difficult for the heart to pump hard enough to force the blood through the legs and back into the main section of the body. Varicose veins occur when the blood begins to pool in the veins in the legs. This can cause the veins to become twisted and gnarled, turning them a dark blue or purple color. On-site ultrasounds can help to detect varicose veins and help doctors to determine their severity.
What is Covidien Vein Ablation?
Covidien Vein Ablation is a technique that involves the use RF waves to ablate the vein and send blood along other pathways. Similar to sclerotherapy, the procedure blocks off the damaged veins. By blocking off the damaged veins, the blood is forced to flow through other veins in the area that are healthy and able to handle the new volume. During the procedure, a small incision is made in which an endovenous catheter is inserted through which RF or radiofrequency waves are used to effectively block or collapse the veins. With the damaged veins, blocked off, healthy circulation is restored.
Can Varicose Veins be Prevented?
Varicose veins may not be able to be prevented. People who are subject to vascular problems due to their genetic makeup may be predisposed to varicose and spider veins. Even though varicose veins cannot be prevented, the risk of having them can be reduced. One of the best ways to prevent abnormal vascular issues is to maintain an ideal weight. Elevating the feet as a person relaxes will also encourage proper blood flow towards the upper body. Regular exercise is also beneficial. As the muscles are moved during exercise, the friction caused by the movement of the muscles helps to keep the veins healthy and functioning properly.
