A 14-week-old border collie with a history of exercise intolerance was confirmed to have a patent ductus arteriosus (PDA) from colour flow Doppler echocardiography. Under general anaesthesia, angiography was performed to gauge accurately the width of the ductus, and then two intravascular embolisation coils were introduced into the ductus via percutaneous catheterisation of the femoral vein. The coils were both 8 mm in diameter, each with four loops. This led to an immediate disappearance of the murmur. Some slight residual flow was detected at the time of the procedure by angiography, but by 10 days postoperatively there was no PDA flow detectable. The time taken to complete the procedure was 55 minutes, with a total fluoroscopy time of 15 minutes. Placement of intravascular embolisation coils represents a viable alternative to traditional surgical methods of ductus closure.
一只14周大的边境牧羊犬有运动不耐受史，经彩色多普勒超声心动图确诊为动脉导管未闭（PDA）。在全身麻醉下，进行血管造影以准确测量导管宽度，然后通过股静脉经皮导管插入术将两个血管内栓塞线圈引入导管。线圈直径均为8mm，每个有四个环。这导致杂音立即消失。术中血管造影时检测到一些轻微的残余血流，但术后10天未检测到动脉导管未闭血流。完成该手术用时55分钟，总透视时间为15分钟。血管内栓塞线圈置入是传统手术闭合导管方法的一种可行替代方案。
