While ectopic pregnancies account for 1-2% of all pregnancies, abdominal pregnancy is extremely rare, accounting for approximately 1% of ectopic pregnancies. Extrauterine abdominal pregnancy is defined as the implantation and development of an embryo in the peritoneal cavity. The present report is the first of an incidental case of abdominal pregnancy within four full-term foetus simultaneously with 2 weeks of physiological gestation in a healthy doe rabbit.
The doe was born on November 3, 2014 and the first partum took place on May 18, 2015. The doe had previously delivered and weaned an average of 12.0 ± 1.41 live kits at birth (no stillbirths were recorded) during 5 consecutive pregnancies. The last mating was on December 18, 2015 and the detection of pregnancy failure post breeding (by abdominal palpation) on December 31, 2015. Then, the doe was artificially inseminated on January 27, 2016, diagnosed pregnant on February 11, 2016 and subsequently euthanized to recover the foetus. A ventral midline incision revealed a reproductive tract with 12 implantation sites with 15 days old foetus and 4 term foetus in abdominal cavity. There were two foetus floating on either side of the abdominal cavity and two suspended near the greater curvature of the stomach. They were attached to internal organs by means of one or 2 thread-like blood vessels that linked them to the abdominal surfaces.
In our opinion a systematic monitoring of rabbit breeding should be included to fully understand and enhance current knowledge of this phenomenon of abdominal pregnancy.
虽然异位妊娠占所有妊娠的1%-2%，但腹腔妊娠极为罕见，约占异位妊娠的1%。宫外腹腔妊娠定义为胚胎在腹腔内着床和发育。本报告是首例健康母兔同时怀有4个足月胎儿且处于2周生理妊娠期的腹腔妊娠偶然病例。
该母兔出生于2014年11月3日，首次分娩于2015年5月18日。此前，该母兔在连续5次妊娠期间，平均每窝产仔12.0±1.41只活仔（无死产记录）。最后一次交配时间为2015年12月18日，2015年12月31日经腹部触诊检测到妊娠失败。随后，该母兔于2016年1月27日进行人工授精，2016年2月11日诊断为怀孕，随后实施安乐死以取出胎儿。经腹正中切口发现生殖道有12个着床部位，腹腔内有15日龄胎儿和4个足月胎儿。腹腔两侧各有2个胎儿漂浮，胃大弯附近悬吊着2个胎儿。它们通过1条或2条线状血管附着于内脏，这些血管将它们与腹壁相连。
我们认为，应纳入对家兔繁殖的系统监测，以全面了解并增进对这种腹腔妊娠现象的现有认识。
