In Situ Uterine Artery Prostaglandin E and Nitric Oxide in Open-Cervix Pyometra and Medically Treated Bitches.

Uterine vascular alterations take place in pyometra bitches speculatively influenced by prostaglandin and nitric oxide pathways. However, no causative effect of nitric oxide on endometrial vascularization was proved elsewhere for medically treated pyometra bitches. This study aimed to identify the main in situ uterine artery vasodilation pathway in pyometra bitches medically treated with antigestagen solely or coupled with prostaglandin.

Prostaglandin and antigestagen in pyometra bitches: vascular and stereological effect.

Unlabelled: Effects of conservative treatment on uterine blood flow and morphometric findings are still unknown in bitches. Thus, this study aimed to compare uterine changes of pyometra bitches subjected to distinct modes of treatment. Pyometra bitches were assigned to: OHE (ovariohysterectomy immediately after diagnosis), Aglepristone (days 1, 2 and 8) and Associative (aglepristone treatment coupled with cloprostenol for 7 days) groups.

Clinical Changes and Uterine Hemodynamic in Pyometra Medically Treated Bitches.

Cystic endometrial hyperplasia-pyometra complex is a canine endometrial disorder, considered the most common and important among uterine diseases. The treatment of choice is ovariohysterectomy, but medical treatments have become an alternative. However, no studies have been performed in order to evaluate uterine hemodynamic changes during medical treatment for pyometra bitches.
