From January 2005 to July 2008, a retrospective study was conducted at a single institution to investigate technical success of the use of a reentry device (Outback LTD reentry catheter) in aortoiliac and femoropopliteal artery recanalization in 34 patients (18 men; mean age +/- SD, 72 years +/- 11) in whom the conventional guide wires and catheters failed to reenter the true lumen. True lumen reentry was achieved in 87% (n = 23) and 91% (n = 11) of patients with femoropopliteal and aortoiliac occlusions, respectively. The overall technical success rate with the device was 88% (n = 34). The device success rate in Transatlantic Inter-Society Consensus II class D lesions was significantly lower than in lower lesion classes (71.4% vs 100%; P < .05). No procedure-related complications were encountered. In conclusion, the use of the reentry catheter enhances the likelihood of successful subintimal recanalization of chronic occlusions in femoropopliteal and aortoiliac arteries.
从 2005 年 1 月到 2008 年 7 月，在一家医疗机构进行了一项回顾性研究，调查了在 34 名（18 名男性；平均年龄 +/- SD，72 岁 +/- 11 岁）患者中使用再进入装置（Outback LTD 再进入导管）进行腹主动脉和股腘动脉再通的技术成功率，这些患者中常规导丝和导管未能重新进入真腔。股腘动脉闭塞患者中有 87%（n=23）和腹主动脉闭塞患者中有 91%（n=11）成功实现了真腔再进入。该装置的总体技术成功率为 88%（n=34）。该装置在跨大西洋内科学会共识 II 类 D 病变中的成功率明显低于较低病变等级（71.4%比 100%；P<.05）。没有发生与程序相关的并发症。总之，使用再进入导管可提高慢性闭塞的股腘动脉和腹主动脉内膜下再通的成功率。
