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)

1. Adults : Both male and female participants.
2. Diagnosed with critical limp threatening ischemia (CLTI):
significant occlusions in the femoropopliteal
o Rutherford Class 5: Non-healing wounds or ulcers
3. Failed or unable to achieve antegrade access:
Patients requiring retrograde puncture for the procedure.
4. Planned intervention with retrograde access: Candidates for endovascular interventions, including angioplasty, stent deployment
Exclusion criteria:
• Active infection at the puncture site: Any localized infection, particularly over the ankle region , will be an exclusion.
• Severe calcification or anatomical abnormalities: Patients with excessive arterial calcification or significant anatomical distortion preventing safe retrograde puncture.
