The aim of this clinical case presentation was to describe the effect of a 4.7 mg deslorelin implant placement in a pregnant queen during the second half of gestation, and the consequences of its removal on the pregnancy and parturition. A 5-year-old female cat exhibiting nesting behaviour and weight gain 10 days after placement of a deslorelin implant was presented for examination. Gestation was confirmed on ultrasound, with two well-formed kittens of a gestational age of approximately 7 weeks. The deslorelin implant placed on the umbilicus was removed 1 week later. No change in the pregnancy was observed after removal of the implant. The fetuses showed no signs of distress on ultrasound and radiography examination 4 days after removal of the implant. One week after implant removal, the queen naturally delivered two healthy kittens. The queen showed maternal behaviour with normal milk production.
In the light of the lack of literature on implant injection and removal in the pregnant queen, this case report showcases a successful birth of healthy kittens without any subsequent adverse effect on the queen. Further study is needed to assess the safety of implant removal during pregnancy and potential use as a means to induce fertile oestrus in the queen.
本临床病例报告的目的是描述在妊娠后半期给怀孕母猫植入4.7毫克醋酸去甲雄三烯醇酮的效果，以及取出该植入物对妊娠和分娩的影响。一只5岁雌性猫在植入醋酸去甲雄三烯醇酮植入物10天后出现筑巢行为并体重增加，前来接受检查。经超声检查确认妊娠，有两只发育良好、胎龄约7周的小猫。1周后取出置于脐部的醋酸去甲雄三烯醇酮植入物。取出植入物后未观察到妊娠情况有变化。取出植入物4天后，超声和X线检查显示胎儿无窘迫迹象。取出植入物1周后，母猫自然分娩出两只健康小猫。母猫表现出母性行为且产奶正常。
鉴于缺乏关于怀孕母猫植入物注射和取出的文献，本病例报告展示了健康小猫的成功出生，且对母猫没有任何后续不良影响。需要进一步研究以评估孕期取出植入物的安全性，以及其作为诱导母猫发情手段的潜在用途。
