Bilateral hydrosalpinx in a mare - a case report

Abstract

During a research visit for tissue collection at an abattoir located in Pelotas, Brazil, one female genital tract showed both enlarged oviducts. The reproductive tract was collected and analyzed. Occluded uterine tubes and an increase in the organ volume due to the large amount of fluid in the organ lumen were the macroscopic findings. Three samples, corresponding to isthmus, ampulla and infundibulum from each uterine tube and one sample from the endometrium were collected. Samples were fixed in Bouin's solution and processed in light microscopy. Microscopically a decrease in the number of folds and also an increase in the lumen of the organ were observed, mainly in the ampulla and infundibulum. The epithelial lining of the uterine tubes ranged from ciliated to simple squamous. Inflammatory cells were observed between the epithelial cells and in the lamina propria. Hydrosalpinx is difficult to diagnose and can be a cause of infertility in the mare.Keywords: fluid accumulation, uterine tubes, oviducts, equine, female Palavras-chave: acúmulo de fluido, tubas uterinas, ovidutos, equinos, fêmea RESUMO Durante uma visita de pesquisa para coleta de tecido em um abatedouro localizado na cidade de Pelotas, Brasil, foi observado um trato genital com aumento do tamanho dos ovidutos.

Clinical application of hysteroscopic hydrotubation for unexplained infertility in the mare

“…In conclusion, while endoscopic hydrotubation of the oviduct with saline may be beneficial in some cases of unexplained infertility in the mare, structural abnormalities of the oviduct which may be related to infertility, such as hydrosalpinx [32][33][34], and salpingitis [32,35] associated with abnormal development or adhesions have also been reported. In these and other cases of oviductal abnormalities, laparoscopy can be a useful additional diagnostic aid [31], whereas these abnormalities would not be appropriate candidates for the present treatment.…”
