Use of a balloon occlusion catheter to facilitate transarterial coil embolisation of a patent ductus arteriosus in two dogs

Two dogs with a history of coughing and exercise intolerance were suspected to have a patent ductus arteriosus (PDA), and the presence of a type III P DA was confirmed by radiography, electrocardiography, ultrasonography and a ngiography. Transarterial coil embolisation was carried out by using a modi fied technique. An occlusion balloon catheter was inserted through a femora l vein and placed at the pulmonary side of the ductus before the embolisati on culls were put in place. Both dogs remained healthy during a follow-up p eriod of nine months.
