Heartworm caval syndrome (CS) occurred in three dogs under 2 years of age. A 23-month-old dog was recovered by surgical and medical treatments, but the other 2 dogs (15 and 21 months old) died. Necropsy demonstrated 12 heartworms in the 15-month-old dog and 8 worms in the 21-month-old dog. Histopathologically, pulmonary arterial embolism caused by dead worms and thrombi were observed in these cases. The findings suggested that CS could develop regardless of canine age and worm burden if pulmonary arterial embolism related to worm death or thrombus formation were induced.
心丝虫腔静脉综合征（CS）发生在3只2岁以下的犬只身上。一只23个月大的犬只通过手术和药物治疗后康复，但另外2只犬只（15个月和21个月大）死亡。尸检显示，15个月大的犬只体内有12条心丝虫，21个月大的犬只体内有8条心丝虫。组织病理学检查发现，这些病例中均观察到死虫和血栓引起的肺动脉栓塞。研究结果表明，如果诱发与虫体死亡或血栓形成相关的肺动脉栓塞，无论犬只年龄和虫体负荷如何，都可能发生CS。
