The accuracy of Duplex ultrasound scanning in locating the sepheno-popliteal junction (SPJ) was assessed by comparison with clinical examination and short saphenous venography. Twenty-three legs with varicosities of the short saphenous system had their SPJ located by Duplex scanning and marked pre-operatively. Varicography was performed on all patients. Clinical examination localised the junction to within 2 cm in 8/23 (37%) compared to 16/23 (74%) for Duplex ultrasonography and 21/23 (93%) venography. Ihis study shows that Duplex ultrasonography while more accurate than clinical evaluation, should not replace venography in the pre-operative localisation of the SPJ.
通过与临床检查和小隐静脉造影相比较，评估了双功超声扫描定位隐-腘静脉交界处（SPJ）的准确性。对23条存在小隐静脉系统静脉曲张的下肢进行双功扫描定位SPJ，并在术前进行标记。对所有患者均进行了静脉造影。临床检查将交界处定位在2厘米范围内的比例为8/23（37%），而双功超声检查为16/23（74%），静脉造影为21/23（93%）。本研究表明，双功超声检查虽然比临床评估更准确，但在SPJ的术前定位中不应取代静脉造影。
