A female mongrel dog (1 year old, 6.3 kg) was admitted with a sign of severe paralysis of hind limbs due to automobile accident. Radiographic examination revealed fifth lumbar vertebral fracture and pelvic fracture. By laminectomy and reduction of the lumbar vertebral fracture with pin and wire, nervous function rapidly recovered. In a month postoperatively, almost complete recovery from the paralysis was observed.
A 3-month-old female mongrel dog weighing 0.8 kg was admitted with vomitting and dyspnea post cibum. Physical examination, thoracic radiography and barium sulfate contrast radiography revealed persistent right aortic arch with a esophageal diverticulum. The dog was maintained under feeding of small amounts of liquid diet for 20 days, followed by thoracotomy under general anesthesia. The ligamentum arteriosum was dissected free from the esophagus between the aorta and pulmonary artery. Then surgical removal of the esophgeal diverticulum was performed. After the operation, the dog showed no regurgitation even by giving solid food and the esophagram at 131 days after the surgery revealed that the portion of resection was in a normal condition.
