Abstract
Random skin flaps have been widely used for loss of skin and subcutaneous tissues for thousands of years [1]. Unlike the axial pattern flap, the blood supply of a random pattern flap is based on small unnamed vessels. Most unnamed vessels are part of the subdermal plexus [2]. Partial or complete skin flap necrosis is a common problem encountered postoperatively. Flap necrosis caused by disruption of blood supply within the flap often occurs after the surgery, and requires a secondary operation [1,2].
