Due to the risk of mobilizing plaque fragments, transfemoral TEVAR is a potentially dangerous procedure in patients with a coral reef aorta. We describe a practical method for transfemoral TEVAR in a patient with a degenerative thoracic aneurysm and a coral reef aorta. After placing a filter catheter in the abdominal aorta via a contralateral percutaneous femoral access, a working channel through the distal thoracic aorta was created with a balloon-expandable stent graft in the coral reef segment. Thereafter, transfemoral TEVAR could be performed successfully, without any complications. The additional use of a percutaneously placed filter catheter potentially allows reduction of peripheral embolism and hence may prevent patients from more invasive treatment.
由于斑块碎片移动的风险，经股动脉 TEVAR 对于珊瑚状主动脉的患者来说是一种潜在危险的操作。我们描述了一种对于患有退行性胸主动脉瘤和珊瑚状主动脉的患者行经股动脉 TEVAR 的实用方法。通过对侧经皮股动脉入路将滤器导管置于腹主动脉内后，在珊瑚状节段使用球囊扩张支架移植物在远端胸主动脉内建立工作通道。此后，可以成功地进行经股动脉 TEVAR，没有任何并发症。经皮放置的滤器导管的额外使用可能减少外周栓塞的风险，从而可能防止患者接受更具侵袭性的治疗。
