Real time ultrasound mapping of the greater saphenous vein (GSV) was performed in 30 consecutive patients admitted for in situ femoro-crural revascularisation. The overall accuracy in predicting the adequacy of the GSV for in situ bypass was 90%. The predictive value of finding the vein usable was 96%, whereas the predictive value of judging the vein inadequate was 50%. The scanning procedure provided morphologic information about the GSVs, including size, tributaries, varicosities, and double segments, which may prevent unnecessary dissection and may further shorten the duration of surgery. In our opinion the technique is sufficiently accurate to replace phlebography for the routine preoperative assessment of GSV in patients considered for in situ bypass. Veins judged inadequate at scanning, however, should be further evaluated.
对30例因原位股腘血管重建入院的患者进行了大隐静脉（GSV）的实时超声成像。预测GSV用于原位旁路移植术是否合适的总体准确率为90%。判断静脉可用的预测价值为96%，而判断静脉不合适的预测价值为50%。扫描程序提供了有关GSV的形态学信息，包括大小、分支、静脉曲张和双段情况，这可以避免不必要的解剖，并可能进一步缩短手术时间。我们认为，该技术足够准确，可替代静脉造影，用于考虑原位旁路移植术患者的GSV常规术前评估。然而，扫描时判断为不合适的静脉应进一步评估。
