Two dogs presented with acute tetraparesis, hypoventilation, and bradycardia with a second-degree atrioventricular heart block. Neurological examination localized both lesions to the cervical spine. Diagnostic imaging revealed a ventral extradural compression at the second to third cervical (C(2)-C(3)) region in one dog and at the third to fourth cervical (C(3)-C(4)) region in the other. Following surgical correction of the extruded disk, the hypoventilation and bradycardia resolved. Cervical disk extrusions are a common cause of acute tetraparesis in the dog. This report shows that respiratory and cardiac complications may occur concurrently. The authors recommend screening dogs with cervical myelopathies for respiratory and cardiac dysfunctions and treating appropriately. Prompt surgical intervention and supportive care can improve the prognosis.
两只犬出现急性四肢轻瘫、通气不足和心动过缓，并伴有二度房室传导阻滞。神经学检查发现病变均位于颈椎。诊断性影像学检查显示，一只犬在第二至第三颈椎（C2-C3）区域有腹侧硬膜外压迫，另一只犬在第三至第四颈椎（C3-C4）区域有腹侧硬膜外压迫。在对突出椎间盘进行手术矫正后，通气不足和心动过缓症状得到缓解。颈椎间盘突出是犬急性四肢轻瘫的常见原因。本报告表明，呼吸和心脏并发症可能同时发生。作者建议对患有颈椎脊髓病的犬进行呼吸和心脏功能障碍筛查并给予适当治疗。及时的手术干预和支持性护理可以改善预后。
