Using a Thermal Imaging Camera to Locate Perforators on the Lower Limb

Area of Science:

• Plastic Surgery
• Surgical Oncology
• Medical Imaging

Background:

• Lower limb reconstruction after skin cancer excision is complex due to anatomical challenges.
• High flap failure rates are associated with raising flaps superficial to the deep fascia, contrary to established vascular anatomy.
• Fasciocutaneous flaps offer superior cosmetic outcomes compared to skin grafts for lower limb reconstruction.

Purpose of the Study:

• To investigate the utility of thermal imaging in identifying perforator 'compartments' for lower limb flap design.
• To propose an improved method for designing fasciocutaneous flaps based on perforator identification.
• To reduce flap failure rates in lower limb reconstruction.

Main Methods:

• Utilized a thermal imaging camera to visualize and identify perforator 'compartments' in the lower limb.
• Correlated thermal imaging findings with anatomical vascular planes.
• Applied findings to the design of fasciocutaneous flaps.

Main Results:

• Thermal imaging effectively identified distinct perforator 'compartments'.
• This method aids in precise flap design, respecting deep vascular planes.
• Potential for improved flap survival and aesthetic outcomes.

Conclusions:

• Thermal imaging is a valuable tool for preoperative planning in lower limb reconstruction.
• Identifying perforator compartments using thermal imaging can optimize fasciocutaneous flap design.
• This technique may lead to reduced complication rates and enhanced functional and cosmetic results in lower limb reconstruction.
