Y1 - 2016 N1 - T2 - Williams Gynecology, 3e AB - An ectopic or extrauterine pregnancy is one in which the blastocyst implants anywhere other than the endometrial lining of the uterine cavity. Nearly 95 percent of ectopic pregnancies implant in the fallopian tube. Other sites are shown in Figure 7-1, which reflects data from 1800 surgically treated ectopic pregnancies (Bouyer, 2002). Bilateral ectopic pregnancies are rare, and their estimated prevalence is 1 of every 200,000 pregnancies (al-Awwad, 1999).
