摘要
Hysterectomy is a rare method of castration in bitches, due to an increased risk of side effects. Ovariohysterectomy is the most recommended method of surgical castration of a bitch. However, leaving the ovaries decreases the risk of obesity and urinary incontinence. This report describes a 9 year old German Shepherd female (hysterectomized 3 years before) which was refferred to the clinic due to purulent vaginal dicharge and changes of 3,4 and 5th right mammary glands (RMG 3,4,5). During ultrasound examination two ovaries with cysts and inflamation of uterocervical stump were observed. The surgery was carried out, both remaining fibrotic ovaries with cyst together with part of inflammated uterocervical stump were removed. Right semi-mastectomy was also performed (RMG 3,4,5 and inguinal lymph node were removed). The histopathological examination of mammary glands revealed the presence of adenocarcinoma papilliferum. Two months later, after left semi-mastectomy of 2,3,4 and 5th mammary gland (LMG 2,3,4,5) hystopathological examination revealved a complex carcinoma in mammary glands and in inguinal lymph node. Two years after the surgery disseminated neoplasia with metastases to the lungs was diagnosed. Described side effects outweight potenctial benefits of the hysterectomy. To authors knowledge this is the first report of severe consequences of deliberately leaving ovaries in a bitch.
