Intravascular ultrasound-guided reentry wiring with tip-detection technique for chronic total occlusion of lower extremity artery disease.

ABSTRACT:

Background

Endovascular therapy is an effective method for revascularization in lower extremity artery disease, but treating chronic total occlusion (CTO) remains challenging. This is particularly true for patients with severe calcification, poor run-off in below-the-knee arteries, or limited access sites, where even guidewire (GW) passage can be difficult and bidirectional approaches are often not feasible. The tip-detection (TD) method has been reported as a useful technique in coronary artery CTO interventions, allowing real-time visualization of the GW tip direction. Here, we applied the TD technique for peripheral CTO intervention.

Case presentation

Case 1 involved a 71-year-old man with a right toe ulcer. Angiography revealed total occlusion from the right anterior tib
