title: [Closure of a persistent ductus arteriosus of Botallo in two dogs using transarterial coil embolization].
abstract: Non-surgical occlusion of persistent ductus arteriosus (PDA) by catheter guided coil embolisation was performed in two dogs. In both dogs the procedure was performed through the femoral artery. The exact location and the narrowest diameter of the PDA were evaluated angiographically after contrast medium injection into the ascending aorta. Based on shunt diameter measurements of 4 mm in dog no. 1 and 2.4 mm in dog no. 2, a coil of 8 mm diameter was chosen for dog no. 1, and of 5 mm diameter for dog no. 2. The coils were placed within the shunt vessel under fluoroscopic guidance using the Cook delivery-system for detachable PDA coil. The success of the intervention was documented angiographically 10 minutes after coil release. The shunt vessel was completely occluded in dog no. 1, while minimal blood flow was detected in dog no. 2 at that time. The technique of transvascular PDA closure compares favorably with the traditional surgical technique due to minimal invasiveness and hence excellent postinterventional comfort to the patient.
