Veins are blood vessels that carry blood back to the heart. In addition to the skeletal-muscle pump, the venous valves also help here. If these valves are damaged (usually due to predisposition) or do not close completely anymore, venous blood builds up in the legs. The result is discernable, vasodilated veins (varicose veins). As a consequence, strongly cirsoid vasodilated veins are visible: usually, bluish-looking side branches that also appear in the foot area, as well as spider veins.
Frequently, patients experience typical symptoms such as a feeling of heaviness, itching and a burning sensation in the legs. Especially after prolonged sitting or standing, there may also be painful swelling. Skin lesions or poorly healing wounds on the legs can occur in the advanced stage of the condition.
As varicose veins are a chronic condition, they may recur after optimal primary treatment. In the case of recurrent varicose veins (recurrent varicosis) after surgery/treatment, an individualized therapy — depending on results — becomes all the more necessary.
For a diagnosis, a physical examination and an ultrasound examination (duplex sonography) are necessary. After this, various treatment options can be selected.
