A 5-month old, intact, female domestic shorthair cat was referred for evaluation of a heart murmur. Echocardiography revealed a large, left-to-right shunting patent ductus arteriosus (PDA). One month after initial presentation, the cat underwent transvenous PDA occlusion via Amplatz occlusion device. A 4-mm Canine Duct Occluder (ACDO) was successfully placed via introduction into the right jugular vein and retrograde manipulation from the pulmonary artery across the ductal opening. No residual flow was detected postoperatively, and the patient recovered uneventfully without significant complications. At recheck evaluations one and seven months post-operatively, the patient was clinically well with trivial residual diastolic flow and improved left heart dimensions. This report demonstrates the feasibility of transvenous PDA occlusion via ACDO device in the feline patient, although further experience is needed to establish the repeatability and safety of this approach compared with alternative methods.
一只 5 月龄、未去势的雌性家短毛猫因心脏杂音被转诊进行评估。超声心动图显示存在一个大的、左向右分流的动脉导管未闭（PDA）。在初次就诊一个月后，猫通过 Amplatz 封堵器进行了经静脉 PDA 封堵术。通过引入右颈静脉并从肺动脉逆行操作，成功地将 4mm 的犬型动脉导管封堵器（ACDO）放置于动脉导管开口处。术后未检测到残余血流，且患者无明显并发症，顺利恢复。在术后 1 个月和 7 个月的复查评估中，患者临床状况良好，仅有轻微的残余舒张期血流和左心尺寸改善。本报告证明了在猫中使用 ACDO 装置进行经静脉 PDA 封堵的可行性，尽管需要进一步的经验来确定与替代方法相比，这种方法的可重复性和安全性。
