Long term survival of animals with major congenital anomalies is very rare. This report documents the 18-month survival of a dog with multiple anomalies including atresia ani. An 18-month-old black Cocker Spaniel bitch was presented for evaluation of prolapsed glands of the third eyelid involving both the eyes. Clinical examination revealed a single perineal opening, fecal matter in the vestibule, distended abdomen, hypoplastic vulva, and the absence of a tail without any neurological deficits. Abdominal contrast radiography revealed a distended colon with fecal stasis, rectovestibular fistula, termination of the rectum as a blind pouch, lumbar scoliosis due to block vertebrae, and the presence of only two hypoplastic coccygeal vertebrae. The case was diagnosed as atresia ani type II with rectovestibular fistula, hypoplastic vulva, lumbar scoliosis, and anury, in the global context of a caudal regression syndrome. The wide aperture fistula, connected to the vestibule, undamaged spinal cord and sacrum without any neurological deficits were the favorable prognostic factors that maintained continence and allowed the dog to survive to adult life with these anomalies. Thus, an appropriate bowel management program and specialty care can improve the quality of life and longevity of this animal.
患有重大先天畸形的动物长期存活非常罕见。本报告记录了一只患有多种畸形（包括肛门闭锁）的狗 18 个月的存活情况。一只 18 个月大的黑色可卡犬雌性因第三眼睑脱垂的腺体脱垂累及双眼而就诊。临床检查显示只有一个会阴部开口，前庭有粪便，腹部膨胀，外阴发育不全，没有尾巴，没有任何神经缺陷。腹部对比放射摄影显示扩张的结肠有粪便停滞，直肠前庭瘘，直肠末端呈盲袋，腰椎侧凸是由于椎体阻塞引起的，只有两个发育不全的尾骨。该病例被诊断为肛门闭锁 II 型，伴有直肠前庭瘘、外阴发育不全、腰椎侧凸和无尿，在全球范围内属于尾部退化综合征。宽口瘘与前庭相通，脊髓和骶骨完好无损，没有任何神经缺陷，这些是保持控便能力的有利预后因素，使这只狗能够在这些畸形的情况下存活到成年。因此，适当的肠道管理计划和专业护理可以提高这种动物的生活质量和寿命。
