BackgroundEctopic pregnancy (EP), reflecting a fertilized ovum implanted outside the normal uterine cavity, represents a frequent cause of morbidity and possibly mortality in women of reproductive age.
ObjectiveTo summarize the diagnosis and treatment of EP after in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET).
MethodsThe medical records of patients who were diagnosed with EP after embryo transfer from 2017 to 2019, in a tertiary hospital were reviewed.
ResultsOf the 24 cases analyzed, 21 (87.5%) had fallopian tube involvement, while 2 (8.3%) and 1 (4.2%) had cornual and cervical pregnancies, respectively. Clinical manifestations included vaginal bleeding (58.3%) and lower abdominal pain (16.7%); 9 (42.9%) cases had no symptoms. One cornual pregnancy was misdiagnosed as acute appendicitis and later correctly diagnosed by laparoscopic exploration. There were 2 cases of multiple-site EP and 2 of heterotopic pregnancy, including one with an intrauterine pregnancy with double chorionic and four amniotic sacs and right tubal ampullary pregnancy. Five of the 21 cases with fallopian tube involvement received conservative treatment, while the remaining 16 underwent surgeries, including laparoscopic ipsilateral salpingostomy and ipsilateral salpingectomy.
DiscussionEctopic pregnancy after embryo transfer, mainly involving the fallopian tube, is very complex and is with diverse manifestations. Even with the pregnancy sac observed in the uterus, the pelvic cavity should be scanned thoroughly after embryo transfer.
