Subdermal Plexus
Pronunciation: PLEK-sus
The network of blood vessels located in the deep dermis and superficial subcutis.
Full Definition
The subdermal plexus is a horizontal network of blood vessels that runs parallel to the skin surface at the junction between the deep dermis and superficial subcutaneous tissue. This vascular network plays a crucial role in skin perfusion and is an important anatomic consideration in dermatologic surgery. Understanding the location and function of the subdermal plexus is essential when planning surgical procedures, particularly when designing flaps or assessing tissue viability. Disruption of this plexus can compromise skin perfusion and affect wound healing, making preservation of this vascular network a key consideration in reconstructive procedures.
