Echogenic fluid on transvaginal ultrasound accurately indicates hemoperitoneum in suspected ectopic pregnancy cases. This finding has high accuracy, sensitivity, and specificity for surgical confirmation.

Area of Science:

  • Medical Imaging
  • Gynecology
  • Emergency Medicine

Background:

  • Ectopic pregnancy is a life-threatening condition requiring prompt diagnosis.
  • Identifying hemoperitoneum is crucial for managing suspected ectopic pregnancies.
  • Echogenic fluid on ultrasound is a key indicator, but its correlation with surgical findings needs precise evaluation.

Purpose of the Study:

  • To assess the accuracy of echogenic fluid detection via transvaginal sonography in correlating with hemoperitoneum.
  • To determine the diagnostic performance of echogenic fluid for hemoperitoneum in patients with suspected ectopic pregnancy.

Main Methods:

  • Retrospective analysis of 831 patients undergoing transvaginal sonography to rule out ectopic pregnancy over 36 months.
  • Evaluation of pelvic free fluid presence and echogenicity.

  • Correlation of ultrasound findings with surgical documentation of hemoperitoneum in 185 patients (laparotomy/laparoscopy).

    • Main Results:

    • Echogenic fluid was identified in 125 patients; 122 (98%) had confirmed hemoperitoneum at surgery.
    • Anechoic fluid or no fluid detected on ultrasound showed 0% correlation with hemoperitoneum.
    • Echogenic fluid demonstrated 100% sensitivity, 95% specificity, 98% positive predictive value, and 98% accuracy for hemoperitoneum.

    Conclusions:

    • Transvaginal sonography's detection of echogenic fluid is a highly accurate predictor of hemoperitoneum in suspected ectopic pregnancy.
    • Echogenic free fluid is a reliable sonographic marker for intra-abdominal bleeding in this patient population.
    • The findings support the use of transvaginal ultrasonography for rapid and accurate assessment of hemoperitoneum in ectopic pregnancy evaluations.
