Minimally invasive patent ductus arteriosus occlusion in 5 dogs.
OBJECTIVE
To report a technique for minimally invasive occlusion of patent ductus arteriosus (PDA) and outcome in 5 dogs.


METHODS
Clinical cases.


METHODS
Five, 4-6-month-old, dogs with PDA.


METHODS
Titanium ligating clips were used for PDA closure in all dogs. Three dogs had video-enhanced mini-thoracotomy PDA occlusion. Two other dogs had thoracoscopic PDA occlusion using a custom-designed thoracoscopy clip applicator.


RESULTS
Thoracoscopic PDA occlusion was successful in both dogs in which it was attempted. Complete PDA closure was achieved in 4 dogs. Three months after surgery, the largest dog had residual ductal flow that hemodynamically was insignificant.


CONCLUSIONS
Although technically demanding, minimally invasive PDA occlusion is a safe and reliable technique in dogs. Preoperative measurement of the diameter of the PDA is crucial to determine if complete closure with metal clips can be achieved.


CONCLUSIONS
Minimally invasive PDA occlusion should be considered as an alternative to occlusion via conventional thoracotomy.
