Three-dimensional visualization and virtual resection planning improve surgical outcomes for pediatric solid tumors. This innovative approach enhances understanding of complex anatomical relationships for better pre-operative strategies.

Area of Science:

  • Medical imaging
  • Surgical oncology
  • Pediatric surgery

Background:

  • High-resolution computed tomography (CT) and magnetic resonance imaging (MRI) enable 3D tumor visualization.
  • Complex pediatric malignancies often require additional preoperative information beyond standard imaging.

Purpose of the Study:

  • To present a novel model for preoperative 3D visualization and virtual resections in pediatric solid tumors.
  • To assess the feasibility and utility of 3D visualization and virtual surgical planning in pediatric oncology.

Main Methods:

  • Utilized HepaVision2 software for image analysis of pediatric tumors from multislice CT scans.
  • Extracted and analyzed organs, tumors, and vascular systems, calculating vascular territories.
  • Performed virtual resections using InterventionPlanner software and correlated findings with intraoperative results.

Main Results:

  • Successfully applied 3D visualization to pediatric patients (mean age 5 years, 9 months) with hepatic, renal, and other solid tumors.
  • Identified spatial relationships and quantified anatomical structures using colorimetric encoding.
  • Demonstrated successful virtual simulation of tumor resections for planning hepatic and renal tumor surgeries.

Conclusions:

  • 3D tumor visualization and virtual resection simulation provide a foundation for successful complex pediatric tumor resection planning.
  • Further studies with larger cohorts and diverse tumor types are needed to validate the efficiency of these techniques.
