Stripping the long saphenous vein: peroperative retrograde saphenography in patients with and without venous ulceration.
Peroperative retrograde saphenography was used to study 80 incompetent long saphenous veins (LSV) in 60 patients with primary varicose veins. In 53 limbs presentation was uncomplicated (group A, 40 patients); in 27 limbs there was ulceration (group B, 20 patients). All limbs in group B had a normal deep system as shown pre-operatively by ascending and descending venography. Varicose changes were found in 52 (65 per cent) of 80 LSV; the overall mean length of normal vein seen was 16 cm. The incompetent LSV appears unlikely to be suitable for arterial replacement. All valves identified on operative saphenography above the knee appeared incompetent. In only 9 LSV of group B were there recognizable valves either above or below the knee, significantly fewer than 34 of group A (P less than 0.05). This finding suggests that a deficiency of saphenous valves may contribute to the development of venous ulceration. Hunterian perforators of variable size were seen on 70 saphenograms (87 per cent) passing directly from the LSV to the superficial femoral vein. Stripping of the incompetent LSV will disconnect such perforators from an incompetent system and may thus reduce the incidence of both recurrent varicose veins and persistent ulceration.
