Fetoscopy enables advanced fetal surgery, particularly for twin-to-twin transfusion syndrome, with high survival rates and low neurological morbidity. This minimally invasive technique is revolutionizing prenatal diagnosis and therapy.

Area of Science:

  • Minimally Invasive Fetal Surgery
  • Prenatal Diagnosis and Therapy
  • Maternal-Fetal Medicine

Background:

  • Fetoscopy, a minimally invasive endoscopic procedure, has seen a resurgence due to technological advancements.
  • Its application extends to fetal diagnosis and therapy, with emerging roles in endoscopic fetal operations.
  • Obstetrical endoscopy encompasses interventions on the placenta, umbilical cord, and fetal membranes.

Purpose of the Study:

  • To review the current applications and advancements in fetoscopy for fetal diagnosis and therapy.
  • To discuss the efficacy and outcomes of specific fetoscopic procedures, such as laser coagulation for feto-fetal transfusion syndrome.
  • To explore alternative methods for cord ligation and their associated risks and benefits.

Main Methods:

Related Experiment Videos

  • Review of current literature and clinical practices regarding fetoscopy in fetal medicine.
  • Analysis of outcomes for Nd:YAG laser coagulation of chorionic plate vessels in feto-fetal transfusion syndrome.
  • Comparison of fetoscopic cord ligation with alternative methods like bipolar cord occlusion under ultrasound guidance.

    • Main Results:

    • Nd:YAG laser coagulation for feto-fetal transfusion syndrome demonstrates survival rates exceeding 60% with neurological morbidity below 6%.
    • These outcomes compare favorably to serial amnioreductions, suggesting a potential shift in treatment preference.
    • Bipolar cord occlusion under ultrasound guidance is emerging as a safer alternative to complex fetoscopic cord ligation due to reduced risk of membrane rupture.

    Conclusions:

    • Fetoscopy is a valuable tool for fetal therapy, particularly for feto-fetal transfusion syndrome, offering improved survival and reduced neurological complications.
    • Ongoing research and a proposed randomized trial aim to further define the optimal management strategies for this condition.
    • While fetoscopy has limitations for cord ligation, advancements in ultrasound-guided procedures offer promising alternatives.
