What is a common source of the lateral sub dermic plexus?

The lateral sub dermic plexus, which is an important component in understanding venous disorders, is commonly affected by non-saphenous vein incompetence. This plexus encompasses small veins located near the dermis and is often involved in conditions where veins outside of the primary saphenous system exhibit incompetence, leading to venous insufficiency and visible varicosities.

Non-saphenous vein incompetence can contribute to increased venous pressure within the lateral sub dermic plexus, resulting in a compromised flow and the potential for venous pooling. This stands in contrast to other conditions such as stripping surgery, which intentionally removes veins and could lead to changes in venous dynamics but does not serve as a source of the plexus itself. Deep vein thrombosis typically affects larger, deeper veins and may not directly influence the lateral sub dermic plexus. Reticular vein reflux, while potentially impactful in venous health, usually refers to specific smaller veins rather than the wider context of the sub dermic plexus as a whole.

This understanding underscores the importance of recognizing the role of non-saphenous veins in the venous system and their contributions to conditions that affect the sub dermic plexus.
