Segmental uterine aplasia in elective ovariohysterectomy in a bitch – case report

Congenital anomalies of the reproductive system of cats and dogs are rare. Among these, the unilateral agenesis of the uterine horn (unicornuate uterus) is the most frequent anomaly. Due to its rarity and few reports in literature, the aim of this work is to report the finding of uterine segment aplasia in a bitch during elective ovariohysterectomy. Traction of the right uterine horn was attempted after a retro umbilical celiotomy, disclosing a malformation characterized by shortening of the uterine horn, which measured 12 mm with the ovary close to the reduced segment. Malformation encountered during surgical procedures result in difficulties for the surgical team and prolonged surgical time, since other organs and systems can also present anomalies and require therefore careful inspection.
