Bilateral tubal occlusion secondary to asymptomatic ectopic pregnancies.

An infertile woman with normal pelvic anatomy apparently underwent two consecutive asymptomatic tubal pregnancies without surgical intervention. Bilateral tubal obstruction resulted from destruction of the proximal segments of the fallopian tubes. These findings suggest that unrecognized ectopic pregnancies may cause destruction of segments of the fallopian tube and should be considered as an etiology of the rarely noted absence of tubal segments.
