Abstract

A six-month-old, entire female, Irish setter was presented with a two-month history of progressive hindlimb weakness and collapse on exercise. Thoracic auscultation revealed a soft systolic murmur and a split second heart sound. Differential cyanosis and polycythaemia were not observed. Right-to-left shunting patent ductus arteriosus (r-PDA) was confirmed on contrast echocardiography ("bubble study") and selective right ventricular angiography. Comparison of blood gases from the metatarsal and auricular artery confirmed the presence of differential hypoxia. This technique is not known to have been described previously in the diagnostic investigation of r-PDA in dogs.

摘要

一只6个月大的未绝育雌性爱尔兰赛特犬，出现进行性后肢无力和运动时虚脱2个月病史。胸部听诊发现柔和的收缩期杂音和第二心音分裂。未观察到差异性发绀和红细胞增多症。经造影超声心动图（“气泡试验”）和选择性右心室血管造影证实为右向左分流的动脉导管未闭（r-PDA）。比较跖骨动脉和耳动脉的血气证实存在差异性低氧血症。据了解，该技术此前未在犬r-PDA的诊断研究中被描述过。
