intraoperative ultrasound
Real-time ultrasound imaging performed during fetal surgery to guide needle placement, monitor fetal position, and assess procedural progress.
Full Definition
Intraoperative ultrasound involves the use of sterile ultrasound transducers during fetal surgical procedures to provide continuous visualization of fetal anatomy, instrument positioning, and procedural landmarks. This technology enables surgeons to navigate complex anatomical structures, verify instrument placement, monitor amniotic fluid levels, and assess fetal well-being throughout the procedure. The technique is essential for minimally invasive procedures where direct visualization is limited and helps reduce complications by providing real-time feedback on fetal positioning and procedural progress.
Usage
Usage note: Distinguish from diagnostic ultrasound performed before or after surgery.
