The prevalence of saphenofemoral incompetence in a series of 105 consecutive patients undergoing saphenofemoral ligation as part of an operation for primary varicose veins was determined using a directional continuous-wave Doppler ultrasonic device. Saphenofemoral incompetence was correctly predicted in 97% of limbs. Using conventional clinical methods, incompetence was correctly predicted in 82% of limbs. This difference was highly significant (P less than 0.01 McNemar). It is concluded that a directional Doppler ultrasonic assessment is a useful aid in the pre-operative determination of saphenofemoral incompetence.
在105例连续接受大隐静脉高位结扎术（作为原发性静脉曲张手术的一部分）的患者中，使用定向连续波多普勒超声设备测定大隐股静脉瓣膜功能不全的患病率。在97%的肢体中，大隐股静脉瓣膜功能不全被正确预测。使用传统临床方法，82%的肢体中瓣膜功能不全被正确预测。这种差异具有高度统计学意义（P<0.01，McNemar检验）。结论是，定向多普勒超声评估有助于术前确定大隐股静脉瓣膜功能不全。
