Abstract
It has been estimated that between 10% and 20% of adults in United States and Western Europe have varicose (large dilated) leg veins and up to 50% of women by age 50 will have telangiectatic (very small dilated) leg veins. While most patients who present for treatment do so for cosmetic reasons, up to 50% of patients with varicose veins will develop symptoms or adverse sequellae, including superficial thrombophlebitis and leg ulceration. The difference between varicose, reticular, and telangiectatic leg veins is one of size. By convention, a tortuous vein greater than 4–5 mm in diameter is referred to as varicose, a vein between 1 and 4 mm in diameter is referred to as reticular, and a vein less than 1 mm in diameter is referred to as telangiectatic. 1 Telangiectatic vessels can be further subcategorized as linear, arborizing, or spider (Figure 19.1).
