This prospective observational study analyzes endometrial thickness and serum β-hCG levels, identifying their predictive value in medical abortion outcomes.
Key Points
Endometrial thickness and serum β-hCG levels are significant markers for predicting outcomes of medical abortion.
Increased endometrial thickness was associated with incomplete abortions, averaging 14.6 mm compared to 11.2 mm in complete abortions.
A serum β-hCG level threshold of ≥100 IU/L indicated incomplete abortion with a sensitivity of 87.2% and specificity of 78.9%.
These markers should complement clinical evaluations, as they provide valuable insight into predicting late medical abortion failures.
