To report a technique for minimally invasive occlusion of patent ductus arteriosus (PDA) and outcome in 5 dogs.
Clinical cases.
Five, 4-6-month-old, dogs with PDA.
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.
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.
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.
Minimally invasive PDA occlusion should be considered as an alternative to occlusion via conventional thoracotomy.
报告一种微创闭合犬动脉导管未闭（PDA）的技术及5只犬的治疗结果。
临床病例。
5只4 - 6月龄患有动脉导管未闭的犬。
所有犬均使用钛结扎夹闭合动脉导管未闭。3只犬采用视频辅助小切口开胸动脉导管未闭封堵术。另外2只犬使用定制的胸腔镜夹钳进行胸腔镜下动脉导管未闭封堵术。
2只尝试胸腔镜下动脉导管未闭封堵术的犬均成功。4只犬实现了动脉导管未闭的完全闭合。术后3个月，最大的那只犬存在残余导管血流，但血流动力学上无显著意义。
尽管技术要求高，但微创动脉导管未闭封堵术在犬中是一种安全可靠的技术。术前测量动脉导管未闭的直径对于确定能否用金属夹完全闭合至关重要。
微创动脉导管未闭封堵术应被视为传统开胸封堵术的替代方法。
