Piometra canina: relato de caso

Abstract

Pyometra as the most common reproductive disorder in domestic females, in addition to mammary neoplasia, is of greater importance when it comes to bitches, since its etiopathogenesis is not very clear in cats, and preventive castration is much more prevalent in felines than in cats. in canines. It is believed that the process of development of canine Pyometra begins with Cystic Endometrial Hyperplasia (CEH), due to the influence of progesterone, either coming from the corpus luteum (diestrus), or exogenous (contraceptive applications), whose secretory stimulus by these endometrial glands is an excellent culture medium and uterine immunity is reduced as a hormonal influence as well. In addition, it is mostly nonspecific, with or without fever, abdominal distension and vulvar discharge, but two points should be considered as soon as possible, history of use of progestogens and/or recent heat, and compatible image with the diagnosis. As for the laboratory analysis, findings consistent with anemia, leukocytosis, signs of leukocyte toxicity, alterations in the hepatic and renal profile, indicate the ongoing endotoxemia, which can progress to important metabolic disorders and even septic shock if not diagnosed and reversed in time . Aiming to report the case of a 3-year-old bitch of the shith tsu breed, with a complaint of prostration, intense weight loss and anorexia, in addition to recent heat and, consequently, use of progestogen, this work sought to analyze the most recent data in the literature on this disturbance according to what happened in the report, both in laboratory findings and in the outcome of the case. The treatment chosen was the most indicated, therapeutic ovariohysterectomy, and not uterine lavage, since it not only has a good success rate, but also prevents relapses.
