Summary
Three-dimensional reconstruction using CT angiography or MRI aids gastrocnemius muscle flap surgery. This technique improves flap design and surgical accuracy, leading to successful flap survival in all patients.
Area of Science:
- Plastic Surgery
- Medical Imaging
- Surgical Techniques
Background:
- Gastrocnemius muscle flaps are used for wound repair.
- Accurate flap design is crucial for surgical success.
- Preoperative imaging can aid in flap planning.
Purpose of the Study:
- To evaluate the initial clinical application of 3D reconstruction for gastrocnemius muscle flap surgery.
- To assess the accuracy and efficacy of 3D reconstruction in guiding flap design and harvest.
Main Methods:
- Seven patients underwent gastrocnemius muscle flap surgery.
- Preoperative CT angiography or MRI with contrast was used for 3D reconstruction.
- Amira 4.1 software facilitated individualized flap design based on defect size.
Main Results:
- 3D reconstruction accurately visualized flap anatomy, including blood vessels and skin.
- Flap design matched surgical findings in 6 out of 7 cases.
- All 7 flaps survived post-surgery, with one case showing smaller perforating branches than predicted.
Conclusions:
- 3D reconstruction of gastrocnemius flaps using CT angiography or MRI enhances anatomical visualization.
- This technique allows precise marking of flap extent, minimizing intraoperative vascular injury.
- Improved flap design and harvest contribute to better flap survival rates.
