    Summary
    This summary is machine-generated.

    Interstitial and angular pregnancies are rare ectopic pregnancies with potentially severe outcomes. Early diagnosis, often suggested by uterine asymmetry and bleeding, is crucial to prevent catastrophic hemorrhage.

    Area of Science:

    • Reproductive Medicine
    • Gynecology
    • Obstetrics

    Background:

    • Interstitial and angular pregnancies are rare forms of ectopic pregnancy.
    • These conditions occur in specific locations within the uterine cavity, differing from typical tubal pregnancies.
    • Understanding their unique characteristics is vital for appropriate clinical management.

    Observation:

    • The study presents two cases of interstitial pregnancy and one of angular pregnancy.
    • Angular pregnancy implants in the uterine angle, potentially aborting into the uterine cavity.
    • Interstitial pregnancy, a true ectopic pregnancy, implants in the fallopian tube within the uterine wall.

    Findings:

    • Interstitial pregnancies carry a high risk of rupture due to the area's rich vascularization, leading to potentially catastrophic hemorrhage.

  • Preoperative diagnosis is challenging but suggested by a combination of bleeding during pregnancy, absence of fetal tissue after dilation and curettage, and uterine asymmetry.
  • Angular pregnancies may have different outcomes compared to interstitial pregnancies, with a possibility of development or abortion into the uterine cavity.

    • Implications:

    • Increased use of laparoscopy could improve preoperative diagnosis rates for these rare conditions.
    • Timely diagnosis and intervention are critical to prevent severe maternal morbidity and mortality associated with ectopic pregnancies.
    • This case series highlights the importance of recognizing diagnostic clues for interstitial and angular pregnancies to guide surgical and diagnostic strategies.
