Summary

Heterotopic pregnancy, a rare condition of simultaneous intrauterine and extrauterine pregnancies, is increasingly seen with assisted reproductive techniques. Early ultrasound diagnosis is crucial for managing this high-risk obstetric emergency.

Area of Science:

  • Reproductive Medicine
  • Obstetrics & Gynecology
  • Diagnostic Imaging

Background:

  • Heterotopic pregnancy, the coexistence of intrauterine and extrauterine pregnancies, is rare but incidence is rising due to assisted reproductive technologies.
  • The condition presents significant risks, including rupture and maternal mortality, necessitating prompt diagnosis and management.
  • Risk factors are not always apparent, making vigilance essential in early pregnancy assessment.

Observation:

  • A case report details a 25-year-old patient in her second pregnancy, presenting with a confirmed living intrauterine and a coexisting right tubal extrauterine pregnancy at 6 weeks gestation.
  • No specific risk factors for heterotopic pregnancy were identified in this patient prior to diagnosis.
  • The patient underwent laparoscopic surgery for the removal of the right fallopian tube, preserving the intrauterine pregnancy.

Findings:

  • Laparoscopic salpingectomy was successfully performed, resolving the extrauterine component of the heterotopic pregnancy.
  • The patient's intrauterine pregnancy continued to term without complications.
  • The patient delivered a healthy infant at full term.

Implications:

  • This case underscores the critical importance of meticulous ultrasound examinations in early pregnancy, including thorough adnexal evaluation.
  • Early and accurate diagnosis of heterotopic pregnancy through precise imaging can significantly reduce morbidity and mortality.
  • Healthcare providers must remain aware of heterotopic pregnancy as a possibility, even in the absence of typical risk factors, to ensure timely intervention.
