Balloon Angioplasty to Great Saphenous Vein Graft Interposed in RUDI

Vascular access-induced ischemia is an arteriovenous fistula (AVF) complication that can be treated surgically by interposing grafts to improve distal flow. However, over time, the interposed grafts may occasionally experience narrowing, which may require surgical or endovascular interventions for treatment. In this case report, we present a patient who underwent balloon angioplasty to address the narrowing observed in the great saphenous vein graft that had been interposed during a Revision Using Distal Inflow (RUDI) procedure.
