Abstract:
A pregnant dwarf hamster (Phodopus sungorus), of approximately 1 year old, was attended at the veterinary clinic of a higher education institution with clinical suspicion of dystocia. According to the owner, the patient presented signs of labor but failed to deliver. During labor, conservative pharmacological therapy with intramuscular oxytocin was attempted, but without success, resorting to laparotomy. When the peritoneal cavity was accessed, twisting of the right uterine horn was observed, which was congested and with hematomas. Due to fetal infeasibility, ovariohysterectomy was successfully performed and the patient recovered well, without intercurrence. Uterine horn torsion is a well-known and commonly described condition in the reproductive sphere of domestic animals, causing life threat to both mother and the unborn offspring, usually occurring in the final gestation period in several species. However, no previous reports of gravid uterine horn torsion in dwarf hamster were found, making the condition rare in pet rodents, although life-threatening. The present report demonstrates the importance of including uterine torsion, even if rare, within the spectrum of causes of dystocia in hamsters and other pet rodents, and how rapid decision-making by the veterinarian is crucial to favorable evolution of the condition.
