Intrauterine device localization by three-dimensional transvaginal sonography
1Department of Prenatal Diagnosis and Therapy, University Hospital Vienna, Austria.
Summary
Three-dimensional transvaginal ultrasound effectively visualizes intrauterine devices (IUDs) after insertion. This advanced imaging allows for complete IUD assessment, aiding in routine follow-up and early detection of complications.
Area of Science:
- Medical Imaging
- Gynecology
- Ultrasound Technology
Background:
- Intrauterine devices (IUDs) are common contraceptives.
- Routine follow-up is essential to ensure correct placement and function.
- Traditional ultrasound methods may have limitations in visualizing the entire IUD.
Purpose of the Study:
- To evaluate the utility of 3D transvaginal ultrasound for IUD visualization.
- To assess the effectiveness of this technique in routine post-insertion follow-up.
- To determine if 3D ultrasound improves IUD imaging compared to standard methods.
Main Methods:
- 96 women with TCu380A IUDs were examined.
- 3D transvaginal ultrasound was performed using a specialized probe.
- Imaging occurred at a mean of 22 days post-insertion.
Main Results:
- Complete visualization of all IUD parts was achieved in 95% of cases.
- The three-plane mode visualized the entire IUD in 64% of cases; volume rendering aided in 30%.
- Abnormalities like incomplete arm opening (2 cases), cervical displacement (1 case), and concurrent intrauterine pregnancy (1 case) were identified.
Conclusions:
- 3D transvaginal ultrasound offers valuable insights into IUD location post-insertion.
- The technique allows simultaneous imaging of the entire IUD, including shaft and arms.
- This method can minimize examination time, enhancing efficiency in IUD follow-up.
