Shunt-based interventions: Why, how, and when to place a shunt.

Area of Science:

• Medical science
• Surgical innovation
• Fetal medicine

Background:

• Surgical fetal therapy encompasses open and minimally invasive approaches.
• Minimally invasive techniques utilize fetoscopy or ultrasound guidance through small uterine ports.
• Open fetal surgery involves hysterotomy with associated risks.

Purpose of the Study:

• To compare the benefits of minimally invasive fetal intervention versus open surgical techniques.
• To highlight the advantages of fetoscopic and ultrasound-guided procedures.
• To identify fetal abnormalities suitable for ultrasound-guided drainage.

Main Methods:

• Review of surgical fetal therapy categories: open vs. minimally invasive.
• Description of minimally invasive techniques: fetoscopy and ultrasound-guided procedures.
• Identification of fetal conditions treatable with ultrasound-guided drainage.

Main Results:

• Minimally invasive fetal intervention decreases uterine irritability and preterm labor incidence.
• These techniques avoid hysterotomy risks and future cesarean delivery commitment.
• Thoracic fluid-filled lesions and lower urinary tract obstruction are amenable to ultrasound-guided drainage.

Conclusions:

• Minimally invasive fetal therapy provides significant advantages over open surgery.
• Fetoscopic and ultrasound-guided interventions enhance maternal and fetal safety.
• Ultrasound-guided drainage is a viable option for specific fetal abnormalities.
