title: Treatment of patent ductus arteriosus by placement of two intravascular embolisation coils in a puppy.
abstract: A 14-week-old border collie with a history of exercise intolerance was confirmed to have a patent ductus arteriosus (PDA) from colour flow Doppler echocardiography. Under general anaesthesia, angiography was performed to gauge accurately the width of the ductus, and then two intravascular embolisation coils were introduced into the ductus via percutaneous catheterisation of the femoral vein. The coils were both 8 mm in diameter, each with four loops. This led to an immediate disappearance of the murmur. Some slight residual flow was detected at the time of the procedure by angiography, but by 10 days postoperatively there was no PDA flow detectable. The time taken to complete the procedure was 55 minutes, with a total fluoroscopy time of 15 minutes. Placement of intravascular embolisation coils represents a viable alternative to traditional surgical methods of ductus closure.
