Tubal rupture in ectopic pregnancy: is it predictable?

Area of Science:

• Reproductive Endocrinology
• Gynecologic Surgery
• Maternal-Fetal Medicine

Background:

• Ectopic pregnancies (EP) represent a significant cause of maternal mortality, accounting for 10-15% of all pregnancy-related deaths.
• Tubal rupture in ectopic pregnancy is a life-threatening emergency, underscoring the critical need for predictive measures.
• Early identification of risk factors for tubal rupture is essential for timely intervention and improved patient outcomes.

Purpose of the Study:

• To assess the tubal rupture rate across various treatment modalities for ectopic pregnancies.
• To identify predictive markers, specifically human chorionic gonadotropin (hCG) levels and ectopic mass size, for tubal rupture.
• To enhance the clinical management of ectopic pregnancies through improved risk stratification.

Main Methods:

• Retrospective analysis of demographic and clinical data from 211 patients diagnosed with tubal ectopic pregnancy.
• Comparison of clinical characteristics between patients with and without tubal rupture.
• Evaluation of treatment modalities including expectant management, methotrexate, and surgical intervention.

Main Results:

• Tubal rupture occurred in 14.7% of the study cohort.
• Ectopic pregnancy masses smaller than 2 cm in diameter were not associated with tubal rupture.
• An admission hCG level of 1855 IU/L demonstrated 93.5% sensitivity and 29% positive predictive value for tubal rupture.

Conclusions:

• Admission hCG levels and ectopic pregnancy mass size are significant predictors of tubal rupture.
• These parameters can aid clinicians in identifying high-risk ectopic pregnancy cases requiring closer monitoring or immediate intervention.
• The findings support the integration of hCG levels and mass size into risk assessment protocols for tubal ectopic pregnancy.
