Dissecting Superficial Inferior Epigastric Veins Using a Tablet Navigation Device

Area of Science:

• Surgical Navigation
• Medical Imaging
• Augmented Reality

Background:

• Preoperative understanding of vascular anatomy is crucial for safe flap elevation in surgery.
• Computed tomography angiography provides detailed vascular information but requires effective visualization tools.

Purpose of the Study:

• To develop and evaluate an augmented reality navigation device for visualizing and dissecting superficial vasculature.
• To improve the safety and accuracy of flap elevation procedures by providing real-time vascular guidance.

Main Methods:

• Development of an augmented reality navigation system using a tablet, marker, and custom software.
• Integration of computed tomography angiography data to generate patient-specific vascular images.
• Application of the system for dissecting superficial inferior epigastric veins (SIEVs) in various flap surgeries.

Main Results:

• The navigation device successfully guided the dissection of 12 superficial inferior epigastric veins with high accuracy (error < 1 cm).
• Bilateral SIEVs were easily identified using the image overlay system, demonstrating the device's effectiveness.
• The system facilitated safe navigation and dissection of superficial vascular structures.

Conclusions:

• The developed augmented reality navigation device is effective for superficial vascular dissection in surgical planning.
• This technology enhances surgical precision and safety, particularly in flap elevation procedures.
• Future applications may include navigation of deeper anatomical structures.
