Direct puncture of a thrombosed lower extremity bypass graft may be the only angiographic access to the graft when it cannot be opacified or cannulated by conventional angiographic techniques. In 1 patient, fibrinolytic therapy was performed from this approach using the "crossed two catheter" technique previously described for thrombosed dialysis grafts.
当血栓形成的下肢旁路移植物无法通过传统血管造影技术使其显影或插管时，直接穿刺该移植物可能是对其进行血管造影的唯一途径。在1例患者中，采用先前描述的用于血栓形成的透析移植物的“交叉双导管”技术，通过这种方法进行了纤维蛋白溶解治疗。
