Patent ductus arteriosus (PDA) is a frequent congenital cardiovascular anomaly in dogs that can lead to significant hemodynamic consequences if left untreated. This report presents three canine cases of PDA treated by minimally invasive transcatheter closure using a Nit-Occluder® coil or an Amplatzer Vascular Plug II (AVP II) via a transjugular approach. All interventions were uneventful under general anesthesia. Complete PDA closure was achieved in two dogs along with a regression of cardiac remodeling. In one dog, residual shunting persisted following AVP II release, likely due to partial device displacement; however, the patient remained asymptomatic at long-term follow-up. Technical difficulties related to atypical ductal anatomy were encountered in one case but did not impede successful device placement. Rapid post-procedural recovery was observed in all dogs. These results suggest the clinical applicability of transcatheter PDA closure and demonstrate that both AVP II and Nit-Occluder devices represent reliable therapeutic options for canine PDA.
