What is a leg ulcer?<\/span><\/h2>\n

The <\/span>leg ulcer<\/b> is a chronic wound on the lower leg that is difficult to heal and is usually due to impaired circulation. In about 80 % of the cases, this is a <\/span>Ulcus cruris venosum<\/b>which is caused by venous circulatory disorders. Other forms, such as the <\/span>Ulcus cruris arteriosum<\/b> (due to arterial disorders) or the <\/span>ulcus cruris mixtum<\/b> (a combination of venous and arterial causes) also occur, but are rarer.<\/span><\/p>\n

Anatomical basics<\/span><\/h2>\n

Blood circulation in the legs works via a network of superficial and deep veins that transport blood back to the heart against the force of gravity. When the <\/span>Venous valves<\/b> do not close properly, the blood can flow back and accumulate in the veins. This condition is referred to as <\/span>venous insufficiency<\/b> and leads to a chronic increase in pressure in the veins, which can ultimately lead to a leg ulcer.<\/span><\/p>\n

Causes of venous leg ulcers<\/span><\/h2>\n

The main cause of a <\/span>venous leg ulcer<\/b> is <\/span>chronic venous insufficiency (CVI)<\/b><\/a>a disease in which the venous valves lose their function and the blood is no longer transported efficiently to the heart. The persistent backlog of blood in the leg veins leads to permanent overstretching of the vein walls and damages the surrounding tissue. The most important risk factors include<\/span><\/p>\n
