A femoral crossover polytetrafluoroethylene graft was performed in a patient immediately, after a failed iliac endograft limb recanalization, performed 2 years after endovascular aortic aneurysm repair. Although graft patency was confirmed clinically by palpation of groin pulses as well as noninvasively by segmental pressure measurements and Doppler examination, in the immediate postoperative period, duplex ultrasound failed to show any blood flow inside the graft lumen until the fourth postoperative day. Subcutaneous air and air tapped within the wall structure of the graft are possible explanation for the failure to show flow.
在血管内主动脉瘤修复术后2年进行的髂内移植物肢体再通失败后，立即对一名患者进行了股交叉聚四氟乙烯移植。尽管通过触诊腹股沟脉搏在临床上确认了移植物通畅，并且通过分段压力测量和多普勒检查进行了非侵入性确认，但在术后即刻，双功超声直到术后第四天才显示移植物管腔内有任何血流。皮下空气以及在移植物壁结构内抽出的空气可能是未能显示血流的原因。
