We report two feline cases of patent ductus arteriosus (PDA) with pulmonary hypertension (PH). The subjects were both intact domestic shorthair cats, a 4-month-old, 2.5 kg male (case 1) and an 8-month-old, 2.12 kg female (case 2). At the first presentation, left-sided congestive heart failure was diagnosed in case 1 and severe aortic stenosis (AS) in case 2. Following surgical ligation of the ductus arteriosus (DA), furosemide therapy was no longer required in case 1, and the severe AS improved to mild status in case 2 perhaps because of reduced volume overload. In case 2, severe hypoxemia was revealed after surgery; however, this normalized within 96 days after surgery.
我们报告了两例患有动脉导管未闭（PDA）并伴有肺动脉高压（PH）的猫科动物病例。病例均为未绝育的家养短毛猫，一只4个月大、体重2.5千克的雄性猫（病例1）和一只8个月大、体重2.12千克的雌性猫（病例2）。初次就诊时，病例1被诊断为左侧充血性心力衰竭，病例2被诊断为严重主动脉瓣狭窄（AS）。在对动脉导管（DA）进行手术结扎后，病例1不再需要使用速尿治疗，病例2的严重AS可能由于容量负荷减轻而改善为轻度状态。在病例2中，术后出现严重低氧血症；然而，这在术后96天内恢复正常。
