We performed a retrospective study of 56 dogs with Patent Ductus Arteriosus (PDA) to evaluate the indications for and efficacy of transarterial PDA coil embolization. Transarterial PDA coil embolization was conducted in 37 cases (66.1%) and surgical ligation was conducted in 16 cases (28.6%). Three cases (5.4%) were diagnosed as pulmonary hypertension and were excluded from surgical intervention. Although coil dislodgement was observed in the pulmonary artery in one case, no death occurred during coil embolization or surgical ligation. Echocardiography showed that fractional shortening decreased from 35.4 +/- 6.8% to 30.2 +/- 5.9% (P<0.05) after transarterial PDA coil embolization. Although slight residual shunts were observed in 18 cases, transarterial PDA coil embolization was effective treatment of PDA.
我们对56只患有动脉导管未闭（PDA）的犬进行了一项回顾性研究，以评估经动脉PDA线圈栓塞术的适应症和疗效。37例（66.1%）接受了经动脉PDA线圈栓塞术，16例（28.6%）接受了手术结扎。3例（5.4%）被诊断为肺动脉高压，被排除在手术干预之外。尽管在1例中观察到线圈在肺动脉中移位，但在进行线圈栓塞或手术结扎期间没有死亡发生。超声心动图显示，经动脉PDA线圈栓塞术后，缩短分数从35.4±6.8%降至30.2±5.9%（P<0.05）。尽管在18例中观察到轻微的残余分流，但经动脉PDA线圈栓塞术是治疗PDA的有效方法。
