TY - CHAP M1 - Book, Section TI - Sclerotherapy of Large Varicose Veins A1 - Weiss, Robert A. A1 - Weiss, Margaret A. A1 - Beasley, Karen L. Y1 - 2012 N1 - T2 - Sclerotherapy and Vein Treatment, 2e AB - No matter what the size, all varicosities result from an elevated venous pressure that produces dilatation of the vein walls. To effectively treat large varicose veins, abnormal sources of high pressure must be found and eliminated. In treating veins of any size by any method, the best results will be obtained when the treatment plan is based on a complete understanding of the anatomy of the refluxing circuit. Main high-pressure reflux points should be treated first, even though more distal areas may be more visibly disturbing to the patient.
