An increasing proportion of patients with chronic limb-threatening ischemia are older and have multiple comorbidities, including diabetes and renal failure. For those who are not candidates for a surgical bypass, this set of patients presents a challenge to vascular surgeons and interventionalists owing to the complex below-the-knee and increasingly below-the-ankle disease pattern that can fail traditional approaches for endovascular intervention. Two techniques, the retrograde pedal access and the pedal-plantar loop technique, can be useful in these settings and in skilled hands can be used safely, with a high technical success rate. In patients with chronic limb-threatening ischemia who are not candidates for a single-segment saphenous vein bypass, the retrograde pedal access technique can be used not only in the setting of failed antegrade treatment, but also primarily when faced with a difficult groin or as an adjunct during a planned antegrade-retrograde intervention. The pedal plantar loop technique allows for retrograde access to tibial vessels without retrograde vessel puncture and additionally offers the ability to treat the pedal-plantar arch, which may have added benefit in wound healing. We describe the tips and tricks for these two techniques used in our limb salvage practice.
患有慢性肢体威胁性缺血的患者比例日益增加,且年龄较大,伴有多种合并症,包括糖尿病和肾衰竭。对于那些不适合进行外科搭桥手术的患者,由于膝下及越来越多的踝下疾病模式复杂,可能使传统的血管内介入治疗方法失败,这给血管外科医生和介入专家带来了挑战。逆行足背入路和足底襻技术这两种技术在这些情况下可能有用,在技术熟练的医生手中可以安全使用,技术成功率较高。在不适合单段大隐静脉搭桥的慢性肢体威胁性缺血患者中,逆行足背入路技术不仅可用于顺行治疗失败的情况,而且主要用于面对困难的腹股沟情况时,或作为计划性顺行-逆行介入治疗的辅助手段。足底襻技术允许在不进行逆行血管穿刺的情况下逆行进入胫血管,此外还能治疗足底弓,这可能对伤口愈合有额外益处。我们描述了在我们的肢体挽救实践中使用这两种技术的技巧和窍门。
