Road Mapping Guided Puncture Versus Ultrasound Guided Puncture During Retrograde Angioplasty Feasibility and Safety
The study aims to compare the technical feasibility and safety of road mapping-guided versus ultrasound-guided retrograde arterial puncture in patients with (CLTI) as measured by:
* Puncture success rate * Access-related complication rate (e.g., hematoma, vessel dissection, perforation)
