{Abstract}: The construction and utilization of dependable vascular access are essential for hemodialysis. Despite its importance, complications with vascular access are common, significantly impacting patient morbidity and mortality. This report presents a novel approach to treating chronic total occlusion (CTO) in hemodialysis vascular access using the "wire kissing technique" an "externalization and pull-through technique." An 82-year-old woman on hemodialysis had a thrombotic obstruction in her cephalic vein, which conventional methods failed to address. The wire kissing technique allowed the meeting of antegrade and retrograde wires within the CTO lesion, stabilizing the wire and facilitating balloon passage. The externalization and pull-through technique further enabled the balloon to cross the rigid CTO lesion, successfully completing percutaneous transluminal angioplasty (PTA). Post-procedure ultrasonography showed significant improvements in flow volume and resistance index. These techniques, commonly used in coronary and femoral arteries, have not been previously reported for dialysis vascular access. This case highlights a novel and effective solution for overcoming technical difficulties in crossing CTO lesions, potentially improving outcomes in vascular access for hemodialysis patients.
