METHODS: Case report.
METHODS: Eight month old Babydoll sheep wether, 13 kg.
METHODS: The patient presented with a weight half that of its sibling, persistent regurgitation following eating, and delayed growth noted from the age of approximately 2 months, coinciding with the introduction of solid feed into the diet. Plain thoracic radiographs were within normal limits but computed tomography angiography (CTA) confirmed multiple congenital vascular anomalies. The primary finding was esophageal and tracheal entrapment by a PRAA and left LA. Thoracoscopic transection of the LA was performed with a bipolar vessel sealing device with the aid of transesophageal endoscopy.
RESULTS: Immediate improvement in attitude and absence of regurgitation were observed. The patient was discharged and subsequently reintroduced to grazing and long-stem hay, which were previously not tolerated. By 6 months post discharge, the patient\'s weight was 36 kg, comparable to an age-matched sibling and considered appropriate for the stage of growth.
CONCLUSIONS: Thoracoscopic transection of the LA in sheep is a feasible treatment for esophageal compression resulting from a VRA. Surgical intervention resolved the clinical signs and allowed normal digestive rumination, restoring bidirectional esophageal function in a ruminant.
方法:病例报告。
方法:八个月大的娃娃羊,13公斤。
方法:患者的体重是其兄弟姐妹的一半,进食后持续返流,并从大约2个月的年龄开始延迟生长,与在饮食中引入固体饲料相吻合。胸部X光片在正常范围内,但计算机断层扫描血管造影(CTA)证实了多种先天性血管异常。主要发现是PRAA和左LA压迫食管和气管。在经食管内窥镜检查的帮助下,使用双极血管密封装置进行了胸腔镜横切LA。
结果:观察到态度立即改善,没有反流。病人已出院,随后又被重新引入放牧和长茎干草,以前是不能容忍的。出院后6个月,病人的体重是36公斤,与年龄匹配的兄弟姐妹相当,被认为适合成长阶段。
结论:胸腔镜对绵羊LA进行切断术是治疗VRA引起的食管压迫的可行方法。手术干预解决了临床症状,并允许正常的消化反推,恢复反刍动物的双向食管功能。
