A 3-month-old and a 4-year-old cat were presented in the clinic due to regurgitation. The kitten had displayed the symptoms since it had been fed solid foods and was smaller than the litter mates. The 4-year-old cat showed sudden-onset symptoms for 5 days prior to presentation and had a good general condition. Positive contrast thoracic radiographs of both cats in lateral recumbency showed an esophageal dilatation cranial to the heart base and raised a suspicion of foreign material with soft tissue density in this area. In the 4-year-old cat, findings of ventrodorsal thoracic radiographs were compatible with a dextroposition of the aorta and a slightly marked focal left curve of the trachea. The echocardiographic examination of the kitten pictured a right sided aorta, hence a vascular ring anomaly with a dextroposition from the aorta was suspected. Aberrant blood flow as it is seen in a persistent ductus arteriosus was not apparent in the echocardiography. As a result of the sudden development of the clinical signs in the older cat without displaying any former history of regurgitation, an esophagoscopy was performed to exclude an intraluminal esophageal cause for the stricture as well as to extract the foreign material. In this cat, computed tomography imaging also displayed an aberrant left subclavian artery. Both cats recovered well after surgical correction.The diagnosis of a ring anomaly in the kitten via echocardiography is a rare situation. As is the diagnosis of a high-grade esophageal stricture due to a vascular ring anomaly at the age of 4 without a former history of regurgitation.Recovery was excellent in the younger cat. There were no signs of regurgitation 6 months after surgery. The adult cat was in good general condition without clinical symptoms according to the owners when presented for stitch removal. Unfortunately, the adult cat was lost to follow up.
一只3个月大的猫和一只4岁的猫因反流被送到诊所。这只小猫自从开始喂食固体食物后就出现了症状，并且比同窝的小猫体型小。这只4岁的猫在就诊前5天突然出现症状，总体状况良好。两只猫侧卧位的胸部阳性对比造影X线片显示，在心底上方食管扩张，怀疑该区域有软组织密度的异物。在这只4岁的猫中，腹背位胸部X线片的表现与主动脉右旋和气管轻度明显的局灶性左弯相符。小猫的超声心动图检查显示主动脉在右侧，因此怀疑是主动脉右旋导致的血管环异常。超声心动图中未发现动脉导管未闭时出现的异常血流。由于这只老猫突然出现临床症状，且之前没有反流病史，因此进行了食管镜检查，以排除管腔内食管狭窄的原因并取出异物。在这只猫中，计算机断层扫描成像也显示了异常的左锁骨下动脉。两只猫在手术矫正后恢复良好。通过超声心动图诊断小猫的血管环异常是一种罕见的情况。4岁时因血管环异常导致高度食管狭窄且无既往反流病史的诊断也很罕见。小猫恢复得很好。术后6个月没有反流迹象。据主人说，这只成年猫在拆线时总体状况良好，没有临床症状。不幸的是，这只成年猫失访了。
