Of 113 preoperative arteriograms analyzed, 46 (40%) were unsatisfactory to determine operability for femoral-distal bypass. In 23 of these 46 arteriograms, there was complete nonvisualization of calf vessels (Group A) and in the remaining 23, there was limited visualization (Group B). Both prebypass, on-table operative arteriography and Doppler ultrasound recordings were helpful in predicting the best available artery for bypass in all but one patient (4%) in Group A. In Group B, 7 of 23 patients had the site of distal anastomosis altered after prebypass, ontable arteriography. There was no statistical difference in the patency rates of grafts in patients with inadequate visualization (Groups A and B) and those with adequate visualization (67 patients, Group C). Prebypass, on-table operative arteriography, supplemented by preoperative Doppler ultrasound recordings, helps to extend operability and to avoid unnecessary amputation.
在分析的113例术前动脉造影中，46例（40%）对于确定股-腘动脉旁路移植术的可操作性不满意。在这46例动脉造影中，23例小腿血管完全不显影（A组），其余23例显影有限（B组）。除1例患者（4%）外，旁路移植术前的术中动脉造影和多普勒超声记录有助于预测A组中所有患者最合适的旁路移植动脉。在B组中，23例患者中有7例在旁路移植术前的术中动脉造影后改变了远端吻合口的位置。显影不充分的患者（A组和B组）与显影充分的患者（67例，C组）之间，移植物的通畅率没有统计学差异。旁路移植术前的术中动脉造影，辅以术前多普勒超声记录，有助于扩大可操作性并避免不必要的截肢。
