Bir kedide nadir görülen konjenital anomali: Tek taraflı ovaryum agenezi

Kedilerde üreme organlarının konjenital anomalisi nadiren görülür ve etiyolojisi tam olarak bilinmemektedir. Ovaryum agenezi konjenital anomalilerden biridir ve genellikle laparotomi ameliyatları sırasında rastlantısal olarak bulunur. Bu vakada ovariyohisterektomi için kliniğe getirilen 2 yaşlı dişi bir kedi sunuldu. Anestezi ve ameliyat öncesi rutin muayene yapıldı. Fiziki muayeneler ve kan örnekleri sonucunda ameliyat için herhangi bir sorun olmadığı belirlendi. Pre-operatif hazırlıklardan sonra operasyon gerçekleştirildi. Sağ tarafta kornu uteri ve ovaryum tespit edildi. Ancak sol tarafta sadece herhangi bir anormallik bulunmayan kornu uteri gözlendi. Olgu tek taraflı ovaryum agenezi olarak teşhis edildi. Daha sonra serum steroid hormon düzeylerini belirlemek için kan örneği alındı. Serum östradiol ve progesteron düzeyleri 18 pg / ml ve 1.4 ng / ml olarak ölçüldü. Sonuç olarak, laparatomi esnasında tesadüfen teşhis edilen tek taraflı ovaryum agenezinin kedilerde seksüel aktiviteye olumsuz etkisinin olmadığı belirlenmiştir.

The rarely seen congenital anomaly in a queen: Unilateral ovarian agenesis

Congenital malformations of the reproductive system are rarely encountered in queens and etiology is not known precisely. Agenesis of the ovary is one of the congenital anomalies and usually found incidentally during laparotomy operations. In this case, a 2-year-old female cat referred to the clinic for ovariohysterectomy is described. Before anesthesia and surgery, a routine examination was performed. In physical examinations and results of blood samples did not reveal any problem for the operation. After the pre-operative process, ovariohysterectomy was performed. Ovary and the uterine horn were identified on the right-side. However, only the uterine horn without any abnormality was detected on the left-side. The cat was diagnosed with unilateral ovarian agenesis. Then, a blood sample was taken to determine serum steroid hormone levels. Serum estradiol and progesterone levels were measured as 18 pg/ml and 1.4 ng/ml, respectively. As a conclusion, unilateral ovarian agenesis that is incidentally detected the laparotomy procedures were no adverse effect on sexual activity in queens.
