Summary
Preoperative 3D visualization and virtual liver surgery planning improve hepatic resection predictability and success rates. This technology aids in complex liver surgeries by optimizing resection plans and ensuring sufficient liver function post-operation.
Area of Science:
- Medical Imaging
- Surgical Planning
- Hepatobiliary Surgery
Background:
- Hepatic resections are complex surgeries often requiring detailed anatomical understanding.
- Conventional imaging may not fully reveal tumor-neovascular relationships, impacting surgical planning.
Purpose of the Study:
- To assess the impact of preoperative 3D visualization and virtual liver surgery planning on hepatic resection outcomes.
- To evaluate the accuracy and utility of the Liv 1.0 software in planning liver tumor resections.
Main Methods:
- 3D models of liver structures were created from CT scans for 142 patients.
- Virtual liver resections were performed using Liv 1.0 software for surgical planning.
- Virtual plans were correlated with intraoperative findings and outcomes.
Main Results:
- 3D visualization accurately depicted tumor spatial relationships to vasculature.
- Virtual resections guided optimal margin identification and helped avoid over-resection, preserving liver function.
- The software demonstrated high accuracy in measuring liver volume (6.1% error) and facilitated complex hepatectomies not feasible with conventional CT.
Conclusions:
- 3D visualization and virtual surgical planning offer crucial insights for complex hepatic resections.
- This approach enhances the predictability, safety, and success rate of hepatectomy procedures.
