Venous Ulcer






























































           lcers due to venous hyperten-
      Usion is generally due to deep

      vein incompetence, although
      superficial incompetence may
      also be present. It typically ap-
      pears near the ankle around the
      malleoli, perhaps because the
      subcutaneous tissues are less well
      supported here. This accounts
      for more than 80% of leg ulcers
      worldwide.



      Note the absence of ischemic
      changes in the toes.
