A 44-year-old patient with type I diabetes with critical upper limb ischemia of the left hand was referred to our department with ischemic tissue loss and rest pain. After unsuccessful use of the endovascular antegrade approach, retrograde revascularization with percutaneous transluminal angioplasty (PTA) of the ulnar artery and the Palmar arch through the radial artery was successfully performed (the radial to ulnar artery loop technique). Relief of the patient's symptoms was immediate and ischemic lesions were healed at 6-month follow-up. This technique, which has been used for the first time in critical upper limb ischemia, may significantly increase the success rate of percutaneous angioplasty, especially when antegrade recanalization fails.
一位 44 岁的 I 型糖尿病患者左手发生严重的上肢缺血，出现缺血性组织坏死和静息痛，被转诊至我院。该患者曾尝试顺行腔内治疗，但未成功，随后我们采用经皮腔内血管成形术（PTA）逆行开通尺动脉和掌弓，即桡动脉到尺动脉的环技术，成功地进行了治疗。患者的症状立即得到缓解，缺血性病变在 6 个月的随访中得到了愈合。这种技术首次应用于严重上肢缺血，可能显著提高经皮血管成形术的成功率，特别是在顺行再通失败的情况下。
