Medical records of 32 cattle treated for umbilical abnormalities that had undergone ultrasonographic examination of the umbilicus followed by umbilical resection or postmortem examination were reviewed. Thirty of the cattle were between 6 and 240 days old (mean, 73 days); the remaining 2 cattle were a 3-year-old bull and a 5-year-old cow. Thirty (94%) animals had external evidence of infection associated with the umbilicus. Two calves did not have external signs of infection; 1 had an abscess of the urachus and the other was found to be normal. Two-dimensional real-time ultrasonography was used to identify abnormal umbilical cord remnants. Ultrasonographic results were most reliable for the urachus, and the urachus was the most commonly affected internal umbilical cord remnant. Statistical agreement between ultrasonographic and physical (surgical or postmortem) findings was good to excellent for all umbilical structures. Intra-abdominal adhesions were found at surgery in 47% of animals with umbilical abnormalities; however, adhesions were not detected ultrasonographically.
回顾了32头因脐部异常接受治疗的牛的病历，这些牛在接受脐部超声检查后进行了脐部切除或尸检。其中30头牛年龄在6至240天之间（平均73天）；其余2头牛是一头3岁公牛和一头5岁母牛。30头（94%）动物有与脐部相关的感染外部证据。2头犊牛没有感染的外部体征；1头有脐尿管脓肿，另一头检查正常。使用二维实时超声检查来识别异常的脐带残余物。超声检查结果对脐尿管最可靠，脐尿管是最常受影响的内部脐带残余物。对于所有脐部结构，超声检查与体格检查（手术或尸检）结果之间的统计学一致性良好至极佳。在有脐部异常的动物中，47%在手术时发现有腹腔粘连；然而，超声检查未检测到粘连。
