Road Mapping Guided Puncture Versus Ultrasound Guided Puncture During Retrograde Angioplasty Feasibility and Safety

Sponsor

Sohag University

Enrollment

32 participants

Start Date

Feb 1, 2026

Study Type

INTERVENTIONAL

Conditions

Peripheral Arterial Disease Vascular Diseases

Summary

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)

Eligibility

Min Age: 18 Years

Inclusion Criteria7

Adults : Both male and female participants.
Diagnosed with critical limp threatening ischemia (CLTI):
significant occlusions in the femoropopliteal
o Rutherford Class 5: Non-healing wounds or ulcers
Failed or unable to achieve antegrade access:
Patients requiring retrograde puncture for the procedure.
Planned intervention with retrograde access: Candidates for endovascular interventions, including angioplasty, stent deployment

Exclusion Criteria2

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.
