title: Efficacy of subfascial endoscopy in eradicating perforating veins of the lower leg and its relation with venous ulcer healing.
abstract: OBJECTIVE
  The purpose of this study was to investigate the efficacy of subfascial endoscopy by use of a mediastinoscope in the identification and ligation of incompetent perforating veins in patients with venous ulceration of the lower leg.
  
  
  METHODS
  All patients who underwent subfascial endoscopy for venous ulceration between Jan. 1, 1994, and Mar. 1, 1995, at the Sint Franciscus Gasthuis in Rotterdam underwent duplex ultrasound scans of the lower leg before and 6 weeks after operation. The number and localization of the perforating veins on the mediodorsal side were compared with the findings during subfascial endoscopy.
  
  
  RESULTS
  In 20 patients, preoperative duplex examination showed 46 incompetent and six competent perforating veins. During operation the site of 43 incompetent and all competent perforating veins was confirmed. Five additional perforating veins were found at operation (false-negatives). Postoperative duplex ultrasound scans showed six incompetent perforating veins (four persisting and two recurring perforating veins) in four patients, of which the ulcers did not heal in three. The ulcers of the other 17 patients healed.
  
  
  CONCLUSIONS
  Subfascial endoscopy is an efficient technique in identifying incompetent perforating veins in patients with chronic ulceration of the lower leg. The persistence of incompetent perforating veins is related to failure of ulcer healing.
