TAIL ABSENCE AND MICROPHTALMIA ASSOCIATED WITH TYPE I ATRESIA ANI IN A CALF: A CASE REPORT

Abstract

Multiple congenital anomalies in calves generally have poor prognosis, with most cases resulting in death. However, there are insufficient data in the literature regarding this subject. This case report aimed to evaluate a calf that presented with a combination of rare congenital anomalies, specifically atresia ani, microphthalmia, and tail absence. The study material consisted of a one-day-old Simmental calf presented to our hospital with the complaint of the absence of an anal opening. On the basis of clinical and radiographic evaluations, the patient was classified as having type 1 atresia ani. Moreover, further congenital anomalies were detected, including microphthalmia in the left eye and absence of the tail. Since the general condition of the calf was stable, surgical correction of the atresia ani was performed, and postoperative defecation was observed. No treatment was applied for any other anomalies. During the postoperative follow-up, the calf's general condition was determined to be good, and no complications developed. In conclusion, as demonstrated in this case, although the prognosis is generally reported to be poor for calves with multiple congenital anomalies, positive outcomes can be achieved with appropriate surgical intervention and a stable general condition. This case report provides valuable information that could serve as a reference for veterinarians working in this field.
