一例泰迪犬冠状病毒感染伴发急性肺水肿的病理诊断报告

某宠物主人送检1只4月龄泰迪犬,初步确诊为冠状病毒感染,于输液过程中突然死亡。剖检可见整个肺脏呈深红色,肺叶边缘呈粉红色,切面深红色,支气管断端有大量红色液体渗出;剖开气管可见其浆膜面呈暗红色,腔内充满红色清亮液体;心脏左右心室扩张,质地柔软,心尖钝圆,呈心力衰竭心。对各个脏器取材进行病理组织学观察,主要病变表现为肺脏弥漫性淤血、水肿,心肌纤维局部溶解坏死。诊断该犬因感染冠状病毒后初次洗澡应激加重病情,并且随着大量静脉输液导致或加剧急性肺水肿发生,最终造成该犬急性死亡。对该病例进行了系统地病理剖检和组织病理学观察,为犬科动物和其他动物发生类似病症提供一定的参考。
