A 13-year-old neutered male Maltese was referred for paroxysms of coughing and cyanosis, with radiographic evidence of bronchial disease and cardiomegaly. Investigation with echocardiography, bronchoscopy, fluoroscopy and bronchoalveolar lavage led to a diagnosis of myxomatous mitral valve degeneration with insufficiency, ISACHC class II heart failure and bronchomalacia with severe left mainstem bronchial collapse. Persistence of intractable cough despite medical therapy prompted placement of a stent in the left mainstem bronchus. Immediately after stent placement, severe pulmonary oedema developed, thought to be due to compression of the left atrium by the stent or acute lung injury related to stent placement. The dog recovered over a 3-day period with diuretic therapy and positive end expiratory pressure ventilation. Subsequently, the dog died from congestive heart failure 102 days after stent placement, during which time occasional, self limiting coughing episodes occurred.
一只13岁已绝育的雄性马尔济斯犬因阵发性咳嗽和发绀前来就诊，影像学检查显示有支气管疾病和心脏肥大。通过超声心动图、支气管镜检查、荧光透视检查和支气管肺泡灌洗进行的检查，诊断为黏液瘤样二尖瓣退化伴关闭不全、ISACHC II级心力衰竭和支气管软化伴左主支气管严重塌陷。尽管进行了药物治疗，但顽固性咳嗽仍持续存在，促使在左主支气管置入支架。支架置入后立即出现严重肺水肿，认为是由于支架压迫左心房或与支架置入相关的急性肺损伤所致。通过利尿治疗和呼气末正压通气，这只狗在3天内康复。随后，这只狗在支架置入102天后死于充血性心力衰竭，在此期间偶尔出现自限性咳嗽发作。
