The Power of IVUS
Conclusion: IVUS use in femoro-popliteal stenting for TASC II class A to C lesions was associated with a higher rate of primary patency in PAD patients.

Advantages of IVUS Guided Intervention
Pre-intervention 1) High probability to capture the true lumen 2) Identify proximal and distal reference segment landing zones and accurately select stent length 3) Accurately measure and lumen size to maximize stent dimensions 4) Determine when debulking should be considered
Post-intervention 1) Maximize stent CSA relative to reference 2) Ensure full lesion coverage 3) Recognize, diagnosis and treat complications
