Retrieval of tip-embedded inferior vena cava filters using endobronchial forceps is a well-described technique. The tip of dorsally tilted filters may be in proximity to the right renal artery, increasing the risk of arterial injury during retrieval. We present one case that illustrates renal artery injury requiring emergent stent graft repair. The three subsequent cases illustrate techniques that avoid renal artery injury using a femoral and jugular approach with the assistance of an arterial fiducial wire. Renal artery injury is a potential complication during retrieval of filters using endobronchial forceps that can be prevented with careful planning.
使用支气管内钳取出尖端嵌入的下腔静脉滤器是一种已被充分描述的技术。背侧倾斜滤器的尖端可能靠近右肾动脉，增加了取出过程中动脉损伤的风险。我们报告一例说明需要紧急进行支架移植物修复的肾动脉损伤病例。随后的三例病例说明了在动脉基准导丝辅助下，使用股静脉和颈静脉途径避免肾动脉损伤的技术。肾动脉损伤是使用支气管内钳取出滤器过程中的一种潜在并发症，通过精心规划可以预防。
