    Abstract:
    Percutaneous transcatheter closure of persistent ductus arteriosus (PDA) has been well established in the pediatric field. For moderate- to large-sized PDA, the newly developed Amplatzer duct occluder had offered a good solution, but it depends on stiff wire and delivery sheath. We reported two elderly patients of PDA with vascular anatomy too difficult to be antegradely approached and were closed by a retrograde technique by an assisting wire from the descending aorta. The wire served as a guide and tracked the delivery system to cross the ductus from the venous side smoothly. This retrograde wire-assisted technique could be utilized to overcome the PDA of difficult vascular anatomy, which could not be easily fulfilled by conventional antegrade venous approach.
