一只体重 9.9 公斤的 12 岁绝育雌性美国可卡犬因有 2 天的呼吸困难和厌食病史而被送去接受评估。超声心动图显示严重肺动脉高压（估计肺动脉收缩压为 93.4 mmHg），伴有右心增大、肺动脉扩张和右心功能不全。未见左心扩张及先天性心脏分流。通过计算机断层扫描血管造影证实肺血栓栓塞（PTE）。经抗血小板、抗凝治疗后，临床体征及右心超声心动图异常得到改善。这些超声心动图检查结果并非 PTE 特有的，但当排除肺动脉高压的其他原因时，它可以作为 PTE 的规则测试和治疗效果的监测。
A 12-year-old neutered female American cocker spaniel weighing 9.9 kg was presented for evaluation with a 2-day history of dyspnea and anorexia. Echocardiography revealed severe pulmonary hypertension (estimated systolic pulmonary arterial pressure, 93.4 mmHg) with right heart enlargement, pulmonary arterial dilation, and right ventricular dysfunction. The dilation of left heart and congenital cardiac shunt were not observed. Pulmonary thromboembolism (PTE) was confirmed by computed tomographic angiography. After treatment with antiplatelet and anticoagulant, the clinical sign and the echocardiographic abnormality of right heart were improved. These echocardiographic findings are not specific for PTE, but it can be useful as a rule-in test for PTE when other causes of pulmonary hypertension are excluded and a monitor of therapeutic efficacy.
