Chronic Ulcers of the Leg of Venous Origin
IT is estimated that 600,000 ulcers of the leg are treated annually in the United States — an estimated that is extrapolated from a reported incidence 15,000 ulcers of the leg treated annually in Denmark.1 These vast numbers argue a problem, the magnitude of which never has been evaluated in terms of physical disability and economic loss both to the individual and to the community. This study will present the current beliefs and practices in regard to the origin and treatment of the disease.
Classification of ulcers of the lower extremities. On the basis of etiology, six categories of ulcers of the lower extremities are recognized, as follows2:
Arteriosclerosis obliterans with or without diabetes
Embolic or thrombotic occlusion
Local arteriospasm, traumatic or occupational
Chronic ulcerative colitis
This study is concerned chiefly with chronic ulcers in the second category: ulcers of the leg of venous origin.
Anatomy and pathogenesis. An understanding of the fundamental anatomy and pathologic physiology is the basis of rational therapy. The venous anatomy of the lower extremity . . .
