3D Modeling of a Myometrially Embedded Intrauterine Device.

Area of Science:

• Medical Imaging
• Surgical Planning
• 3D Modeling

Background:

• Intrauterine device (IUD) use is increasing globally.
• Malpositioned and deeply embedded IUDs pose challenges for removal.
• Standard imaging modalities may require adjunctive tools for complex cases.

Purpose of the Study:

• To describe a novel technique for visualizing deeply embedded intrauterine devices (IUDs) using 3D models.
• To demonstrate the utility of these models in perioperative planning and patient counseling.
• To assess the feasibility of generating 3D models from standard 2D ultrasound data.

Main Methods:

• A patient with a deeply embedded levonorgestrel IUD underwent transvaginal ultrasound.
• Longitudinal ultrasound images were used to construct a volumetric dataset.
• 3D modeling software segmented the uterus and IUD for spatial analysis and visualization.

Main Results:

• A patient-specific 3D model of the deeply embedded IUD was successfully generated from 2D ultrasound data.
• The 3D model provided precise spatial analysis of the IUD's depth and orientation.
• The model facilitated structured patient counseling and surgical planning.

Conclusions:

• Reconstructing patient-specific 3D models from existing 2D ultrasound data is technically feasible.
• This 2D-derived 3D modeling can serve as a valuable adjunct for visualizing deeply embedded IUDs.
• Further studies are needed to evaluate the reproducibility and clinical impact of this technique.
