Abstract

Background: The optimal endovascular treatment (EVT) for chronic total occlusion (CTO) lesions in patients with peripheral artery disease (PAD) has remained unestablished. We encountered a patient with PAD in whom CTO was successfully treated using a novel technique that involved intravascular ultrasound (IVUS) and angled guiding catheter: IVUS Preceding with Angled guiDing catheter (I-PAD) technique.

Case presentation: A 74-year-old male presented with intermittent claudication attributed to CTO of the right external iliac artery. EVT was performed via the right common femoral artery. We retrogradely advanced the I-PAD system (i.e. partially extending the IVUS transducer portion from the tip of the angled guiding catheter) in the CTO lesion under the real-time guidance of IVUS imaging. We successfully traversed the CTO lesion without the use of a guidewire in approximately three minutes. The procedure concluded successfully without any procedure-related complications, following optimal stenting.

Conclusions: The I-PAD might be an effective technique to accurately, quickly, and safely pass through CTO lesions.

采用新型血管内超声波先导技术（I-PAD）治疗外周动脉疾病的慢性全闭塞。

背景：外周动脉疾病（PAD）患者慢性全闭塞（CTO）病变的最佳血管内治疗（EVT）方法仍未确定。我们曾遇到一名 PAD 患者，采用血管内超声（IVUS）和成角导引导管的新技术成功治疗了 CTO：病例介绍：一名74岁的男性因右髂外动脉CTO而出现间歇性跛行。我们通过右股总动脉进行了 EVT。在IVUS成像的实时引导下，我们在CTO病变处逆行推进了I-PAD系统（即从成角度的引导导管顶端部分延伸出IVUS探头部分）。在大约三分钟的时间里，我们在不使用导丝的情况下成功穿越了 CTO 病变。结论：I-PAD可能是一种有效的治疗方法：结论：I-PAD 可能是准确、快速、安全穿越 CTO 病变的有效技术。
