Unusual ectopic pregnancies: a retrospective analysis of 65 cases.

AIM: The aim of this study was to retrospectively investigate unusual ectopic pregnancies (EP) and compare them with fallopian ones.

MATERIAL AND

METHODS

A total of 1000 cases of ectopic pregnancies were analyzed, including 65 unusual cases. We discussed distribution, incidence, risk factors, examinations, treatments and prognoses.

RESULTS

Ovarian pregnancy was associated with placement of intrauterine device and pelvic inflammatory diseases. Extratubal EP have a high rate of misdiagnosis and presented more serious manifestations. Some unusual EP could be diagnosed by ultrasonography. Ovarian pregnancy was usually manifested as positive culdocentesis. Most of the unusual EP underwent surgery, except some early cervical and corneal pregnancies.

CONCLUSION

Although extratubal pregnancies are difficult to diagnose, some histories and auxiliary examinations could make diagnosis easier for clinical physicians. Surgery is still the most effective approach for treatment of unusual EP, while conservative treatment of mifepristone combined with methotrexate or curettage could be used for early diagnosis and treatment of cervical pregnancy.
