Recanalization of graft limb occlusion can prove challenging and the use of the GoBack crossing and reentry device may be a suitable option, especially when there is no other way to restore flow with an usual endovascular approach. The GoBack catheter is a novel device designed to enhance pushability, and to enable direction-change inside hard plaques and crossing of tough lesions, even when they involve graft fabric. It’s reported a case of a 76-year-old male who presented with claudication, previous placement of an aorto-bi iliac graft by open surgery for a ruptured abdominal aneurysm 10 years ago that, over time, developed severe kinking on the left limb and a fabric occlusion on the right limb. After several unsuccessful attempts to cross the occlusion of the right common iliac artery, the GoBack™ was deployed to create a lumen through graft’s folds. After angioplasty and stenting a satisfactory result was achieved, restoring flowCT-scan at 1 month and duplex ultrasound (DUS) at 3 months confirmed the patency of ilio-femoral axis. The advent of this new CTO crossing device has the potential to facilitate recanalization of some of the most challenging occlusions. Facilitating more consistent distal entry and allowing for a decrease in crossing time. Therefore, the GoBack catheter should be considered as a potential complementary tool to treat vascular occlusions via endovascular approaches, especially when classical endovascular techniques fail.

使用 GoBack 导管对塌陷的髂肢进行跨假肢再通：病例报告

移植肢体闭塞的再通可能具有挑战性，使用 GoBack 穿越和折返装置可能是一个合适的选择，尤其是当没有其他方法可以通过常规血管内方法恢复血流时。GoBack 导管是一种新颖的装置，旨在增强可推动性，并能够在硬斑块内改变方向并穿过坚硬的病变，即使它们涉及移植织物。据报道，一名 76 岁男性出现跛行，10 年前因腹部动脉瘤破裂而通过开放手术植入主动脉-双髂骨移植物，随着时间的推移，左肢出现严重扭结和右肢的织物咬合。在多次尝试穿过闭塞的右侧髂总动脉失败后，部署 GoBack™ 以通过移植物的褶皱创建管腔。血管成形术和支架置入术后取得了满意的结果，1 个月时恢复 flow CT 扫描和 3 个月时双工超声 (DUS) 证实了髂股骨轴的通畅。这种新型 CTO 交叉装置的问世有可能促进一些最具挑战性的闭塞的再通。促进更一致的远端进入并允许减少穿越时间。因此，应将 GoBack 导管视为通过血管内方法治疗血管闭塞的潜在补充工具，尤其是在经典血管内技术失败时。1 个月时恢复 flow CT 扫描和 3 个月时复查超声 (DUS) 证实了髂股骨轴的通畅。这种新型 CTO 交叉装置的问世有可能促进一些最具挑战性的闭塞的再通。促进更一致的远端进入并允许减少穿越时间。因此，应将 GoBack 导管视为通过血管内方法治疗血管闭塞的潜在补充工具，尤其是在经典血管内技术失败时。1 个月时恢复 flow CT 扫描和 3 个月时复查超声 (DUS) 证实了髂股骨轴的通畅。这种新型 CTO 交叉装置的问世有可能促进一些最具挑战性的闭塞的再通。促进更一致的远端进入并允许减少穿越时间。因此，应将 GoBack 导管视为通过血管内方法治疗血管闭塞的潜在补充工具，尤其是在经典血管内技术失败时。
