Plain-English summary
A group of 56 dogs diagnosed with a heart condition called patent ductus arteriosus (PDA) underwent a minimally invasive procedure to close the abnormal blood vessel. The procedure was performed through a vein in the leg, using special devices like coils and plugs to block the duct. In most cases, the closure was successful, with only a small number of complications and a very low risk of death. This method proved to be safe and effective, even for smaller dogs weighing less than 2.5 kg, and most dogs showed no significant blood flow after the procedure.

Abstract
OBJECTIVE: Document safety and efficacy of transvenous catheter occlusion of patent ductus arteriosus (PDA) over a wide range of ductal and patient sizes. ANIMALS, MATERIALS AND METHODS: Retrospective study of fifty-six consecutive dogs referred to Colorado State University with diagnosis of PDA. All cases utilized the transvenous approach, via the femoral vein. Occlusion was achieved using a coil (Flipper) in dogs with PDA minimal dimension of <or=4 mm. Amplatzer duct occluder or Amplatzer vascular plugs were used in dogs with PDA minimal dimension >4 mm, or if a coil was unstable following deployment. RESULTS: Ductal occlusion was achieved using the transvenous route alone in 54/56 dogs (96.4%). Occlusion was achieved using detachable Flipper coils in 39/42 dogs (92.9%) in which coil occlusion was attempted, with 38/39 dogs (97.4%) requiring only a single coil. In 16 dogs, occlusion was achieved using an Amplatzer duct occluder or vascular plug. Post-procedure residual ductal flow was absent or only mild in 36/39 (92.3%) dogs in which it was assessed. Procedural mortality rate was 1.7%, and major complication rate 7.0%. CONCLUSION: Transcatheter occlusion via a transvenous approach is a safe and effective method for treating PDA in dogs and is useful for small dogs (<2.5 kg).
