Objective:
To report a case of a habitual aborter that had a pregnancy reach near term and successfully delivered a viable female infant.
Design:
Report of a unique case of a G10P1 that was successfully able to maintain a pregnancy by maintaining serum levels of estradiol and progesterone at or above 200 pg/dL and 25 ng/dL respectively. This case provides a benchmark for exogenous support of estradiol and progesterone throughout pregnancy.
Setting:
A private advanced reproductive center.
Patient:
39-year-old G10P1091 diagnosed to have antiphospholipid syndrome but continued to have continuous miscarriages despite accepted treatment. In addition, 8 products of conception were sent for cytogenetic testing and all were found to be normal.
Interventions:
Examination, laboratory studies, imaging, clinical judgment, and knowledge of previous treatment failures were used to guide the treatment of this patient. Fertility was achieved with continuous supplementation of progesterone, estrogen, LMW-heparin, and prednisone.
Main Outcome Measure:
Delivery of viable infant.
Results:
This advanced reproductive age woman had three subsequent pregnancies. While compliant with our prescribed protocol, the patient successfully carried two pregnancies to viability.
Conclusion:
Clinicians should be alert to the possibility of a luteal phase defect when a patient presents with recurrent fertility problems and multiple spontaneous abortions.
