Sm. Qasim et al., RECURRENT CERVICAL PREGNANCY AFTER ASSISTED REPRODUCTION BY INTRAFALLOPIAN TRANSFER, Obstetrics and gynecology, 87(5), 1996, pp. 831-832
Background: Cervical pregnancy is an uncommon, yet potentially catastr
ophic form of ectopic pregnancy. Early diagnosis and intervention are
important in avoiding short-term and long-term morbidity. Although tra
nscervical embryo transfer is thought to increase the incidence of thi
s phenomenon in patients undergoing in vitro fertilization, its occurr
ence after intrafallopian transfer is rarely seen. Case: A 43-year-old
nulliparous white female with a history of unexplained infertility ex
perienced recurrent cervical pregnancy after two consecutive gamete/zy
gote intrafallopian transfer cycles. Abnormally rising beta-hCG levels
combined with transvaginal sonography helped establish the diagnosis
in each case. Intramuscular (IM) methotrexate combined with intra-amni
otic potassium chloride successfully treated this condition initially,
and IM methotrexate alone was sufficient for successful treatment in
the second case. Conclusion: Cervical pregnancy may occur with assiste
d reproductive techniques involving intrafallopian transfer. Early dia
gnosis may be important for successful treatment of cervical pregnancy
with conservative measures. Even in the case of recurrence, prompt in
tervention may allow for preservation of a patient's future fertility
potential.
