Abstract

OBJECTIVE:

To present four cases of twin tubal pregnancies and discuss possible etiologies. Twin tubal pregnancies are a rare event, with incidence rates estimated as 1 out of 725-1,580 of tubal pregnancies.

DESIGN:

Case series.

SETTING:

Department of obstetrics and gynecology at a tertiary health care facility.

PATIENT(S):

All women with twin tubal pregnancy diagnosed and treated in the department during the years 2007-2009, according to electronic files and histologic reports.

INTERVENTION(S):

None.

MAIN OUTCOME MEASURE(S):

Artificial reproductive technique preceding twin tubal pregnancies

RESULT(S):

We diagnosed four twin pregnancies of 163 tubal pregnancies, an incidence of 2.4%. Of the four cases, two conceived after gonadotropin stimulation and intrauterine insemination. The third conceived following in vitro fertilization and intracytoplasmic sperm injection. The fourth was a spontaneous conception diagnosed as monochorial monoamniotic twin tubal pregnancy.

CONCLUSION(S):

Twin tubal pregnancies may not be as rare as previously thought. Three of the four cases identified during a 2-year period followed artificial reproductive technique. We hope that this report will promote the study of the epidemiology of this event, improve diagnosis, and encourage the development of treatment modalities.
