The varicose tendency cannot be cured but it can be controlled. Injection compression sclerotherapy, if performed competently on selected patients, is an effective treatment. It is a relatively simple, economical, safe, and ambulatory form of therapy which has a major place in the management of varicose veins. The technique for injection is subject to considerable variation, but the necessity for post injection compression of the veins is absolute. Post injection compression reduces the potential for recurrence by preventing return of the blood to the vein after injection and maintaining contact of the intimal surfaces so that bonding can occur, thus converting the vein from a tube to a solid fibrotic cord. Injection compression sclerotherapy is the best treatment of selected varicosities.
