This intensive, case-based course provides practicing interventional radiologists with advanced strategies in the evaluation and endovascular management of critical limb-threatening ischemia (CLTI). Emphasis is placed on complex anatomy, chronic total occlusions (CTOs), below-the-ankle/pedal loop revascularization, deep venous arterialization for the “no-option” patient, and considerations for hybrid/multidisciplinary approaches. Through interactive lectures, live case reviews, technical pearls, and hands-on skills lab, participants will develop expertise in decision-making, advanced device techniques, complication management, and optimizing complex limb salvage outcomes.

Learning Objectives:

Recognize and classify CLTI: Apply updated Global Vascular Guidelines (GVG), WIfI (Wound, Ischemia, foot Infection) staging, and imaging criteria to risk stratify patients.
Master advanced crossing strategies: Compare and employ antegrade, retrograde, transcollateral, pedal, and combined access techniques for complex infrainguinal occlusions
Optimize below-the-knee and pedal interventions: Select devices and techniques for infrapopliteal revascularization, pedal loop reconstruction, and below-the-ankle interventions.
Understand the principles and patient selection for deep venous arterialization (DVA). Perform technical steps of DVA: crossing into the venous system, outflow creation, and adjunctive therapies.
Integrate new technologies: Assess evidence and best practices for drug-coated balloons, drug-eluting stents, atherectomy, intravascular lithotripsy, microcatheters, and specialty wires in CLTI.
Manage complications: Anticipate and treat dissection, perforation, embolization, and no-reflow syndromes in high-risk tibial and pedal interventions.
Incorporate a multidisciplinary approach: Incorporate opportunities to collaborate with other CLTI specialties including vascular surgery, podiatry, wound care, and infectious disease to maximize limb salvage and patient outcomes.
Evaluate real-world cases: Apply advanced endovascular strategies through interactive review of complex case scenarios, including bailout and hybrid solutions.
