ABSTRACT
The damages of long-lasting arteriovenous malformations (AVMs) to the arterial system and to the skin are well known. However, knowledge about damages to the venous system or to the bones is not generally known. Once the first symptoms appear, the AVM should be treated. The dilatation of the arterial system as well as the large dilatations of single veins of the venous system can be treated by reconstructive surgery. Long-lasting AVMs produce secondary venous hypertension, and such a dilatation of the superficial venous system results in a severe congestion syndrome. These numerous veins should be extirpated or surgically occluded in order to reduce the complaints of the patients. Bone length is influenced by the AVMs, resulting in increased length, e.g., of the legs.
