Abstract

A vaginal speculum examination of a 17-month-old Holstein heifer with a history of repeated artificial insemination (AI) failures via the cranial vagina revealed the presence of an intact hymen (imperforate hymen) beyond the external urethral orifice, which resembled the vaginal wall. An ultrasonographic examination detected hypoechoic fluid within the vaginal cavity between the intact hymen and the cervix, indicating the presence of hydrocolpos. After sedation and epidural anesthesia, the intact hymen was incised using a scalpel and scissors and removed, while the incised portions were sutured using a simple interrupted method. The heifer became pregnant after three consecutive estruses with the intervals of approximately 20 days and concomitant AIs. The heifer gave birth to a healthy male calf with no complications after a 291-day gestation period. This case reports the presence of an imperforate hymen with hydrocolpos in a Holstein heifer, followed by successful insemination, conception and delivery after removal of the imperforate hymen.

질을 경유한 반복된 인공수정 실패의 병력을 가진 17개월령 홀스타인 미경산우에서, 질경 검사로 바깥요도구멍 후방에 무공질판막의 존재를 확인하였으며, 이것은 질벽과 비슷한 외관을 보여주었다. 초음파검사 결과 질판막과 자궁경 사이 질강 내에 저에코성 액체의 존재, 즉 질수증의 동반을 확인하였다. 미경산우를 진정 및 경막외마취 후, 수술용 칼과 가위로 무공질판막을 절개 및 제거하였으며, 절개 부위는 단순결절봉합 하였다. 미경산우는 약 20일 간격의 3회 연속 발정에 따른 인공수정 후 임신되었으며, 수정일로부터 291일 경과 후 건강한 수컷 송아지를 순산하였다. 본 증례는 홀스타인 미경산우에서 질수증을 동반한 무공질판막의 발생과 질판막의 제거 수술 후 성공적인 인공수정, 임신 및 분만을 보고한다.
