It is believed by the investigators of recurrent venous varicosity of lower limbs that phlebography aids to detect errors of the performed operative procedure and to reveal what caused the recurrence. The authors' experience comprise 48 distal, ascending, vertical phlebographies, and 47 pelvic and retrograde femoral ones in 60 patients, both explorations being utilized for 28 lower limbs. Distal phlebography in 44 of 48 examined patients indicated insufficiency of perforated veins that caused the recurrent crural varices. It is considered that in surgical therapy for venous varicosity a due consideration should be given for both a liquidation of recognized errors of the preceding surgery and a correction of pathological changes in deep veins of the lower extremities.
