Primary peritoneal pregnancy is extremely rare in the category of extrauterine pregnancy and usually has wide attachment to the peritoneal surface at the implantation site.
A 37-year-old woman had severe lower abdominal pain 13 days before laparotomy for a preoperative diagnosis of extrauterine pregnancy. The conceptus was implanted on the pedicle originating from the left infundibulopelvic ligament. A fresh embryo of approximately 6 weeks' gestation was found in the conceptus.
Primary peritoneal pregnancy may become pedunculated, and implantation on the infundibulopelvic ligament may be involved in the formation of the pedicle. A pedunculated pregnancy may increase the risk of early termination. The reflux theory may be one of the mechanisms in this case.
原发性腹腔妊娠在宫外孕类型中极为罕见，且在着床部位通常广泛附着于腹膜表面。
一名37岁女性在剖腹手术前13天出现严重下腹痛，术前诊断为宫外孕。孕体着床于源自左卵巢悬韧带的蒂上。在孕体中发现一个约6周妊娠的新鲜胚胎。
原发性腹腔妊娠可能形成有蒂的，且着床于卵巢悬韧带可能参与蒂的形成。有蒂妊娠可能增加早期终止的风险。逆流理论可能是该病例的机制之一。
