Summary
The rabbit dorsal flank flap has a consistent twin angiosome blood supply system, ideal for microvascular research. Its perforating vessels are reliably sized for anastomosis, making it a valuable model.
Area of Science:
- Plastic Surgery
- Anatomy
- Vascular Biology
Background:
- The rabbit dorsal flank flap is a widely used model in microvascular and flap research.
- Understanding its vascular anatomy is crucial for successful experimental design and clinical application.
Purpose of the Study:
- To assess the constancy and caliber of the blood supply to the rabbit dorsal flank flap.
- To characterize the vascular pattern and territories of this flap model.
Main Methods:
- Vessel sizes of the main pedicle were measured in 24 live rabbits.
- Lead oxide arteriograms were performed to evaluate vascular patterns and territories.
Main Results:
- A regular twin angiosome supply pattern was observed in over 85% of animals.
- The thoracodorsal vessels supplied a median of 59% and deep circumflex iliac vessels 41% of the flap.
- Vessel sizes (artery/vein: 0.9/1.2 mm and 0.7/1.0 mm) were suitable for microvascular anastomosis.
Conclusions:
- The rabbit dorsal flank flap exhibits a predictable vascular supply suitable for microvascular research.
- The consistent anatomy and vessel caliber support its utility as a flap model.
