[Stripping using invagination over a calibrated stent].

After crossectomy which remains the most important stage, a short stripping is performed in an upward direction, substituting a packing for the olive shaped knob normally used. The width of this gauze packing depends on the diameter of the saphenous vein. Traction of the lower end of the stripper, at the ankle, pulls down the packing within the saphenous vein, causing its invagination. The saphenous vein is thus turned outside in over the packing as it comes out through the lower incision. Besides, this packing ensures haemostasis and is only removed at the end of the procedure. Advantages of this method: absence of haematomas and nerve lesions. Smaller lower incision.
