Intraoperative ultrasound recording of great saphenous vein (G) and accessory saphenous vein (A). Transaxial image of the mid thigh. The great saphenous vein is located beneath the saphenous fascia and measures 2.7 mm in internal lumen diameter. The accessory saphenous vein measures 2.6 mm in diameter. White arrowheads indicate saphenous fascia. Black arrowheads identify muscular fascia. Vertical axis, full scale, is 20 mm.

3. Fig 2
Intraoperative ultrasound recording of varicose veins (V) and great saphenous vein (large white arrowhead). Transaxial image of the mid calf. Varicose veins are located above the saphenous fascia. The small white arrowheads identify the saphenous fascia and adjacent border of varicose veins. The great saphenous vein is located beneath the saphenous fascia and above the muscular fascia and measures 1.6 mm in internal lumen diameter. Vertical axis, full scale, is 30 mm.

4. Fig 3
Percent great saphenous vein (GSV) segment distribution for normal-caliber vein segments, internal lumen diameter greater than 2 mm and less than 5 mm, in normal limbs, limbs with venous telangiectases, and limbs with varicose veins. Four great saphenous vein segments are identified in each limb. The abscissa notations >=1, >=2, and >=3 indicate that at least one, two, and three normal-size great saphenous vein segments are identified by ultrasound in the limb. The abscissa notation “4” indicates that four great saphenous vein segments are identified. There is a decreased incidence of suitable great saphenous vein segments for conduit use in limbs with varicose veins compared with normal limbs (p < 0.001). The distribution difference between normal limbs and limbs with telangiectases is of borderline significance (p = 0.054).
