Vet. Set. 2007 8 2 205-207 JOURNAL OF Case Report Veterinary Science Retrieval of an embolization coil accidentally dislodged in the descending aorta of a dog with a patent ductus arteriosus Seung-Gon Lee Changbaig Hyun Section of Small Animal Internal Medicine School of Veterinary Medicine Kangwon National University Chuncheon 200-701 Korea A intact female miniature poodle weighing kg was referred to the Veterinary Teaching Hospital at Kangwon National University because of inadvertent aortic embolization by an occlusion coil used for the closure of patent ductus arteriosus PDA . The coil was found at the site of the branching renal arteries in the abdominal aorta. A foreign body forceps with a three-wire nail tip was used with fluoroscopic guidance to retrieve the coil. After the removal the dog was treated with heparin to prevent thromboembolization. Key words closure coil dog embolization PDA retrieval In the fetus the ductus arteriosus develops to divert blood from the not yet functioning fetal lungs back into the systemic cfrculation. After birth the ductus arteriosus is closed by a rapid increase in arterial oxygen tension once the animal starts to breathe. Patent ductus arteriosus PDA is the first or second most common congenital heart defect in dogs it is characterized by failure of spontaneous closure of the ductus arteriosus 7 8 . Surgical ligation of the ductus arteriosus was the most common method used to correct this congenital defect before the introduction of transarterial coil embolization in veterinary practice. Since this procedure does not requfre open thoracic surgery it has dramatically reduced the mortality caused by hemorrhage or sudden cardiac arrest. Transarterial PDA coil embolization is a safe cost effective less invasive alternative treatment offered by many specialty centers for PDA occlusion. This procedure involves catheterization of the femoral artery under general anaesthesia. An angiogram is then performed to .
