Sclerotherapy is an injection procedure to treat blood vessel malformations including spider veins and varicose veins. The procedure involves injection of a sterile solution into the veins using a very fine needle. This solution irritates the vein lining causing it to undergo fibrosis and eventually disappear. This book provides an introduction to sclerotherapy for practising dermatologists. Beginning with an overview of venous anatomy, the next chapters examine the pathophysiology of varicose veins and clinical signs of venous insufficiency. The following sections explain the techniques of sclerotherapy and potential complications. The book concludes with discussion on sclerotherapy for cystic and benign vascular lesions, and surgical treatment of varicose veins. Clinical photographs and figures further enhance the comprehensive text.
