    Abstract:
    1. The aim of the present study was to evaluate the clinical value of colour Doppler application in encircling constriction of the superficial femoral vein in deep vein insufficiency. 2. A total of 87 patients with primary deep venous insufficiency (PDVI) using ascending venography were randomly divided into group A (44 patients) and group B (43 patients). All patients underwent encircling constriction of the superficial femoral vein, high ligation and ablation of the great saphenous vein and perforator vein. The duration of venous reflux at operation was monitored with colour Doppler in group A (but not group B) to evaluate the immediate effects. Clinical grading and scoring of the clinical, etiological, anatomical, pathophysiological (CEAP) classification system were used to evaluate the follow-up curative effect. 3. In four cases from group A, completely destroyed valves were identified at the time of operation and autografting of the vein segment with a valve was carried out. The intraoperative examination of colour Doppler in group A showed a much shorter duration of vein reflux after the encircling constriction procedure than the presurgery condition. According to the results of CEAP grading, the success rate of group A (95.0%, 38/40) was significantly higher than that of group B (76.7%, 33/43). Postoperative clinical scores were markedly lower than preoperative scores in both groups A and B. 4. In conclusion, our data suggest that application of colour Doppler in encircling constriction of superficial femoral vein might enhance surgical pertinence and improve surgical effect for PDVI.
