Summary
Three-dimensional (3-D) sonography effectively visualizes fetal hydrops, detailing skin edema, effusions, and ascites. This advanced imaging aids in prenatal diagnosis and understanding of fetal development in utero.
Area of Science:
- Medical imaging
- Fetal medicine
- Obstetrics
Background:
- Hydrops fetalis is a serious condition characterized by abnormal fluid accumulation in fetal compartments.
- Early and accurate diagnosis is crucial for management and improving outcomes.
Purpose of the Study:
- To characterize the three-dimensional (3-D) sonographic features of hydrops fetalis.
- To evaluate the utility of 3-D sonography in visualizing fetal hydrops.
Main Methods:
- Six cases of hydrops fetalis, ranging from 15 to 32 weeks of gestation, were examined.
- Transabdominal 3-D sonography using a 3.5 MHz transducer was employed.
Main Results:
- Before 20 weeks gestation, 3-D sonography allowed clear visualization of internal organs through transparent-like fetal skin.
- After 25 weeks gestation, significant findings like skin edema, pleural effusion, and ascites were well depicted.
- Hypoplastic lungs were clearly identified in cases with pleural effusion.
Conclusions:
- Three-dimensional sonography offers a novel and effective method for in utero visualization of hydrops fetalis.
- This technique enhances the prenatal assessment of fetal anomalies.
