Early pregnancy failure: study by ultrasonic and hormonal methods
Obstetrics and Gynecology
|January 1, 1980
Summary
Ultrasonic examination is the primary diagnostic tool for early pregnancy failure. Hormonal tests, like human chorionic gonadotropin (hCG), provide valuable supplementary information, especially before nine weeks gestation.
Area of Science:
- Reproductive Endocrinology
- Medical Imaging
- Obstetrics
Background:
- Early pregnancy failure is a common complication.
- Accurate diagnosis is crucial for patient management.
- Ultrasonic and hormonal markers are used for evaluation.
Purpose of the Study:
- To assess the diagnostic value of ultrasound and hormonal assays (hCG, E2, P) in early pregnancy failure.
- To determine the optimal combination of methods for diagnosing specific pregnancy complications.
Main Methods:
- Prospective study of 188 patients with early pregnancy failure.
- Utilized ultrasound for fetal life detection and structural assessment.
- Measured plasma levels of human chorionic gonadotropin (hCG), estradiol (E2), and progesterone (P).
Main Results:
- Negative ultrasound for fetal life after 9 weeks predicted 100% failure.
- Positive ultrasound predicted delivery in 90% of threatened abortions.
- Pathologic hCG or P levels indicated miscarriage in 93%; combined levels showed 100% failure.
- Ultrasound combined with hCG was useful for ectopic pregnancy diagnosis.
- Ultrasound alone was sufficient for blighted ovum detection.
Conclusions:
- Ultrasonic examination is the fundamental diagnostic method for early pregnancy failure.
- Hormonal assays, particularly hCG, offer valuable adjunct information, especially before 9 weeks gestation.
- The combination of methods improves diagnostic accuracy for specific conditions like ectopic pregnancy.
