title: Color duplex ultrasound in the assessment of primary venous leg ulceration.
abstract: METHODS
  To determine the extent and severelity of venous reflux, color duplex ultrasound was used in 370 limbs of 303 patients with primary varicose veins. The clinical findings were classified according to the CEAP (clinical, etiologic, anatomic, pathophysiologic) clinical classification.
  
  
  RESULTS
  Of 370 limbs, 32 showed previously healed ulcer (Class 5) and active ulcer (Class 6). Overall reflux in the superficial venous system was seen in 28 limbs (87.5%), and solitary superficial vein incompetence was detected in 13 (40.6%). Reflux was detected throughout the length of the superficial vein system, and the retrograde peak velocity was greater than 30 cm/second in these limbs. Reflux in the perforating veins was detected in 14 limbs (43.8%), but isolated perforating vein incompetence was seen in only one limb (3.1%). Deep vein incompetence was detected in 12 limbs (37.5%). Concomitant superficial and perforating vein reflux was evident in 4 limbs (12.5%) and 2 limbs (6.3%), respectively, but isolated deep vein incompetence was detected in only one limb (3.1%). The operations indicated were selective stripping of the long saphenous vein in the thigh, high ligation of the short saphenous vein, subfascial ligation of perforating veins, and compression sclerotherapy for varicose tributary veins. Healing of the ulcers was achieved within 1 month after surgery, and the postoperative color duplex scanning revealed correction of deep vein incompetence.
  
  
  CONCLUSIONS
  These data suggest that ablation of the superficial vein system and the perforating veins is an appropriate method for the management of patients with primary venous leg ulceration.
