For isolated internal iliac artery (IIA) aneurysms with tapered anatomy extending from the common iliac artery (CIA) to the external iliac artery (EIA), upside-down deployment of an iliac limb after IIA embolization is a practical alternative. However, conventional techniques for upside-down modifications typically require external removal, inversion, and reinsertion of the stent-graft, which can be cumbersome and time-consuming. This study presents the first report of a simplified upside-down deployment technique that utilizes the Minos iliac limb. After cutting the nose cone, a 12 Fr Minos iliac limb was preloaded in reverse orientation into a 14 Fr sheath, without external manipulation or reloading. Following distal IIA embolization, the stent-graft was deployed by unsheathing to accommodate the tapered anatomy from the CIA to the EIA. This technique provides a streamlined, off-the-shelf solution for anatomically challenging iliac aneurysms and offers an effective alternative when standard deployment methods are not feasible.
对于解剖形态呈锥形、从髂总动脉（CIA）延伸至髂外动脉（EIA）的孤立性髂内动脉（IIA）动脉瘤，在IIA栓塞后倒置植入髂支是一种可行的选择。然而，传统的倒置改造技术通常需要将支架移植物外部移除、翻转并重新插入，这可能既繁琐又耗时。本研究首次报告了一种利用米诺斯髂支的简化倒置植入技术。在切割鼻锥后，将一个12F的米诺斯髂支以反向预装入一个14F的鞘管中，无需外部操作或重新装填。在远端IIA栓塞后，通过拔出鞘管来展开支架移植物，以适应从CIA到EIA的锥形解剖结构。该技术为解剖结构复杂的髂动脉瘤提供了一种简化的、现成的解决方案，并在标准植入方法不可行时提供了一种有效的替代方案。
