Plain-English summary
A group of four dogs continued to have a heart murmur after surgery to close a patent ductus arteriosus (PDA), a condition where a blood vessel fails to close properly. To fix this, veterinarians used a minimally invasive procedure called coil embolization, which successfully blocked the remaining blood flow through the PDA. Within three months, two of the dogs showed no signs of residual flow, and all dogs had improved heart measurements. This procedure appears to be a safe option for dogs needing further treatment after initial surgery for PDA.

Abstract
UNLABELLED: OBJECTIVE; To describe use of coil embolization to occlude residual flow through a patent ductus arteriosus (PDA) after incomplete surgical ligation. STUDY DESIGN: Clinical study. ANIMALS: Dogs (n=4) with continuous murmur after surgical ligation of PDA. METHODS: After PDA ligation, residual ductal flow through the PDA was visible on color-flow Doppler examination and left ventricular end-diastolic diameter remained increased. Coil embolization by an arterial approach was performed to achieve complete occlusion of the PDA. RESULTS: Embolization coils were delivered without complications and hemodynamically successful occlusion was achieved. Doppler-visible flow resolved in 2 dogs within 3 months after embolization. Left ventricular end-diastolic diameter indexed to body weight decreased in all dogs. CONCLUSIONS: Transcatheter coil embolization appears to be a safe and minimally invasive procedure for complete occlusion of residual PDA flow after incomplete surgical ligation. CLINICAL RELEVANCE: Transcatheter coil embolization should be considered for correction of hemodynamically significant residual shunts in dogs that have incomplete PDA occlusion after open surgical ligation.
