Summary
This summary is machine-generated.

Three-dimensional (3D) printing of liver models aids complex liver surgery planning. These patient-specific 3D prints enhance visualization of critical vascular structures and improve surgical orientation, especially for challenging cases.

Area of Science:

  • Surgical Innovation
  • Medical Imaging
  • Additive Manufacturing

Background:

  • Three-dimensional (3D) reconstruction of liver anatomy, particularly vascular structures, is valuable for surgical planning.
  • 3D printing applications in medicine remain relatively rare despite its potential.

Purpose of the Study:

  • To evaluate the utility of 3D printing in planning complex liver surgeries.
  • To assess the benefits of 3D printed liver models in visualizing critical surgical areas.

Main Methods:

  • Ten challenging liver surgery cases utilized full-size 3D prints alongside CT scans for pre-operative planning.
  • 3D models incorporated transparent parenchyma, major vessels, and tumors, with biliary trees included if requested.

Main Results:

  • 70% of cases required vascular reconstructions during surgery.
  • Surgical teams reported significant benefits in visualizing vascular infiltration, planning reconstructions, and intraoperative orientation for multifocal tumors.

Conclusions:

  • 3D printed liver models can optimize operation planning in complex liver surgery, especially when vascular reconstruction is anticipated.
  • Further prospective studies are necessary to quantify the clinical impact of 3D printing in liver surgery compared to other 3D visualization methods.
