Objectives:
Subfascial endoscopic perforator surgery (SEPS) is usually performed for posteromedial perforators in the supine position, but subfascial endoscopic perforator surgery for posterolateral perforators in the prone position has not been reported.
Methods:
A 51-year-old male suffered from a venous stasis ulcer around his lateral malleolus because of reflux in the small saphenous vein and incompetent perforating veins around the ulcer.
Results:
Stripping of the small saphenous vein and subfascial endoscopic perforator surgery utilizing screw-type ports was successfully conducted in the prone position.
Conclusions:
The prone position enables interruption of the posterolateral perforators, because gravity-dependent flattening of the muscles enables creation of sufficient subfascial space.
