SYNPOSIS

Dr. Madassery walks through his approach from pre-procedure planning to final scaffolding. The conversation begins with imaging review, patient selection, and anesthesia considerations, emphasizing how preparation influences technical success. They then examine venous mapping and access strategy, with specific attention to femoral and tibial disease patterns and how these anatomic variables shape crossing techniques.
This episode also covers wire and catheter selection, techniques for creating the arteriovenous anastomosis, balloon sizing, valve management, and stent scaffolding. Throughout, Dr. Madassery shares practical solutions to common access challenges and highlights decision points that can determine procedural durability. The discussion closes with reflections on clinical management, operator fatigue, and the value of professional networks when navigating complex limb salvage cases.
