M. Kasum et al., SIMULTANEOUS BILATERAL TUBAL PREGNANCY FOLLOWING IN-VITRO FERTILIZATION AND EMBRYO-TRANSFER, Human reproduction, 13(2), 1998, pp. 465-467
A case of simultaneous bilateral tubal pregnancy resulting from in-vit
ro fertilization and embryo transfer is presented. Repeated transvagin
al ultrasound examinations confirmed an intrauterine sac but no fetus.
A diagnosis of early missed abortion was incorrectly made and a curet
tage was performed. The pathological examination showed the presence o
f decidua and Arias-Stella phenomenon but no chorionic villi. Diagnost
ic laparoscopy and laparotomy performed 40 days after embryo transfer
(eighth week of gestation), revealed bilateral tubal pregnancy. Bilate
ral salpingectomy was performed.
