The aim of this study was to establish the value of color-duplex scanning in a group of patients with varicose veins and another group of patients with with recurrent varicose veins.
During a 6-month period, 170 patients with varicose veins were examined: one group of 106 lower extremities and another group of 99 lower extremities previously operated for varicose veins. The material included 102 women and 68 men with a mean age of 48 years. The patients were classified according to oedema, lipodermatosclerosis, healed and active ulcer. A Diasonic Gateway 2 and 5 MHz scanner head were used for the examination of the patients in a standing position in the groin, midthigh and in the popliteal fossa. Reflux in the superficial and deep venous system, obstruction in the deep system and insufficient operation were recorded.
In the non-operated group 84% of the varicose veins were classified as primary. Three of four ulcers belonged to that group. In the operated group 42% of the cases were due to insufficient treatment. In 33% new sites with reflux were classified. Five of six ulcers could be ascribed to deep venous insufficiency.
Color-duplex scanning is applicable for the determination of the anatomic placement of the chronic venous insufficiency in patients with varicose veins, previously operated or non-operated. In this material 80% of lower extremities could be selected to a possible operation. Operation of the remaining cases would be worthless.
