Angiographic study of the subdermal plexus: a preliminary report.

The subdermal plexus was pictured angiographically in five fresh cadavers injected systemically with a lead oxide-gelatin mixture. Subdermal plexus was found either in the subdermal plane or in the deep part of the dermis. Diameters of vessels in the subdermal plexus are not uniform and there are differences in vascular continuity, which means that the subdermal plexus does not always have a random pattern. This observation is important when designing a thin flap.
