AbstractWhen Doppler ultrasound was introduced for the assessment of patients with varicose veins, a more accurate clinical appraisal of the pathophysiology of this condition became possible. In particular, it enabled identification of those patients with recurrent varicose veins who had had inappropriate or inadequate initial treatment. It facilitated planning of appropriate further treatment.The more widespread use of radiology, in particular varicography, as a means of preoperative assessment of recurrent varicose veins has enabled a more accurate definition of the abnormal anatomical features. The extension of this principle to the operating room has made surgery for recurrent varicose veins more precise.Patients with varicose veins secondary to deep venous disease remain a problem. When both superficial and deep venous disease are present, superficial venous disease should be treated as appropriate. Deep venous insufficiency will require continued supervision of support maintained by bandages or graduated elastic stockings.
