The procedure requires a video camera, specialized instruments and techniques developed for laparoscopic surgery. An endoscope with specially made attachments is inserted in a small incision above the knee. Once the vein is located, a special device tunnels around the vein, cutting and sealing tributary blood vessels. The tunnel is expanded with an infusion of carbon dioxide so the vein can be easily seen and removed. A length of vein from the knee to the groin can be removed with as few as two or three 1-inch incisions.
Patients can expect some bruising and leg swelling, which usually subside in a few weeks.

Anatomical factors and variations in the vein also may make it challenging to use the technique. New acne treatment.
