Summary
The subdermal plexus, crucial for thin flap design, is located in the subdermal plane or deep dermis. Its vascular patterns are not always random, impacting surgical planning.
Area of Science:
- Anatomy
- Vascular Biology
- Surgical Planning
Background:
- The subdermal plexus is a key vascular network.
- Understanding its anatomical distribution is vital for reconstructive surgery, particularly flap design.
Purpose of the Study:
- To visualize and characterize the anatomical distribution and pattern of the subdermal plexus.
- To assess the implications of the subdermal plexus's vascular architecture on thin flap design.
Main Methods:
- Angiographic imaging was performed on five fresh cadavers.
- Systemic injection with a lead oxide-gelatin mixture was used to delineate the vascular network.
Main Results:
- The subdermal plexus was located in either the subdermal plane or the deep dermis.
- Vessel diameters within the plexus were non-uniform.
- Vascular continuity exhibited variations, indicating non-random patterns in some instances.
Conclusions:
- The subdermal plexus exhibits variability in its anatomical location and vascular patterning.
- These findings are significant for optimizing the design of thin flaps in surgical procedures.
- Awareness of the plexus's non-random nature is essential for successful flap viability.
