Ultrasound guided intrauterine transfusion.

Area of Science:

• Maternal-Fetal Medicine
• Perinatology
• Medical Imaging

Background:

• Rh sensitization poses a significant risk to fetuses, potentially leading to hemolytic disease.
• Intrauterine transfusion (IUT) is a critical intervention for managing severe fetal anemia due to Rh incompatibility.
• Traditional IUT methods may involve radiation exposure and carry risks of inaccurate needle placement.

Purpose of the Study:

• To evaluate the efficacy and safety of a novel real-time ultrasound-guided technique for intrauterine transfusion.
• To assess the success rate and neonatal survival associated with this minimally invasive procedure.

Main Methods:

• A total of 12 IUT procedures were performed on 9 Rh-sensitized women.
• Real-time ultrasound guidance was used to precisely insert a needle into the fetal peritoneal cavity through a placenta-free zone.
• An epidural catheter was advanced through the needle for transfusion, with needle placement confirmed by fluid aspiration or air injection.

Main Results:

• The ultrasound-guided IUT procedure was successful in 11 out of 12 instances (91.7%).
• One patient required multiple attempts for needle placement and subsequently developed complications.
• The neonatal survival rate in this cohort was 22% (2 out of 9 infants).

Conclusions:

• Real-time ultrasound guidance offers a safe and effective method for performing intrauterine transfusions.
• This technique minimizes radiation exposure and enhances the precision of needle placement, reducing potential complications.
• Further research may be warranted to optimize outcomes and improve neonatal survival rates in Rh-sensitized pregnancies.
