[Study on correlation of valvular function of deep vein and clinical symptoms]

The material consists of 291 cases (299 limbs) in which all limbs have varicosity of superficial vein. Routine conventional venographic examinations were performed. Valsalva's test was adauted to observe the valvular function of the deep vein. The statistics showed close corelationship between valvular functional state and clinic manifestations (P < 0.005). In maintenance of the normal function of the vein in lower extremities, the valvular function of femoral vein together with that of the popliteal vein is better than each alone. The valvular function of the femoral vein is more efficient than that of popliteal vein.
