Síndrome do ovário remanescente em cadela: relato de caso

Abstract

Remaining Ovary Syndrome (ROS) is defined as an iatrogenic complication after the OSH elective or therapeutic is made, which histologically confirmed ovarian tissue remains in the abdominal cavity, and may be uni or bilateral. Affected animals may show signs of proestrus or estrus, such as vulvar swelling, serosanguineous secretion and acceptance to copulate. The permanence of these tissues and the continuous production of estrogen and progesterone, allows the occurrence of uterine neoplasms, besides the possibility of a higher risk of developing mammary neoplasms, among other complications. The diagnosis is made through anamnesis, the patient's clinical history, and its confirmation is done through laboratory tests such as vaginal cytology, hormonal analysis, and ultrasonography. The most used treatment is surgery through exploratory laparotomy, which the ovarian tissue fragments will be removed. This paper presents a case report of SOR in a female dog, submitted to OSH at two years of age, which routinely presented estrus behavior and breast tumors. Abdominal ultrasound showed the presence of two ovaries, confirmed by exploratory laparotomy.
