title: Tubal pregnancy following tubal embryo transfer into the contralateral fallopian tube.
abstract: Ectopic and heterotopic pregnancy may occur with increased frequency following assisted reproductive technology (ART) procedures. In addition, there may be unusual sites of implantation, which may cause atypical and confusing clinical manifestations. We present a case of tubal pregnancy after tubal embryo transfer (TET) to the contralateral fallopian tube. Four embryos were transferred to the left fallopian tube by laparoscopy, but the patient developed a right tubal pregnancy, possibly as a result of intrauterine or intra-abdominal migration of the embryo. ART patients must be followed closely soon after the procedure, and there should be a high index of suspicion for an unusual implantation site.
