[Substitute valve at popliteal vein in treating deep venous valve insufficiency of lower extremities].

OBJECTIVE

To study the effectiveness of substitute valve at the popliteal vein in treatment of deep venous valve insufficiency of lower extremities.

METHODS

From January 1996 to August 2002, 27 patients were diagnosed having deep venous valve insufficiency of lower extremities by color Doppler and radiography with an average disease course of 17.4 years. All 27 patients had varicose vein, 25 pain, 22 swelling, 25 pigmentation in ankle area and 19 chronic ulcerations. Two cases had been treated with great saphenous vein ligation and striping. Average vein pressure in resting position was (11.00 +/- 0.73) kPa, and the ambulatory venous pressure was (9.14 +/- 0.68) kPa. All patients were treated with substitute valve at the popliteal vein, and great saphenous vein ligation and stripping, some were treated with subfascial endoscopic perforating veins ablation.

RESULTS

The average ambulatory venous pressure after operation was (5.94 +/- 0.82) kPa, were significantly different from that before operation(P < 0.01). The curative results were satisfactory, and all symptom and physical sign disappeared. After a mean follow-up period of 2-6 years, 21 cases had satisfactory results.

CONCLUSION

Substitute valve at the popliteal vein have the value of widespread application.
