The concept of delaying a skin flap is well established and has been implemented into plastic surgery practice for years. Some investigators have delayed musculocutaneous flaps to improve the perforator inflow. To our knowledge, the concept of delaying a muscle flap had previously never been tested in a model with segmental pedicles. Five cats each underwent 3 sequential operations providing them with a sartorius muscle whose blood supply was a single distal pedicle. The opposite leg was used as a control. Our delayed type IV muscle flap demonstrated perfusion to the proximal tip of the sartorius muscle without necrosis or loss of muscle mass (P < 0.0001). The control showed no evidence of perfusion beyond the distal portion of the muscle when infused through the distal pedicle. The delayed flap can survive on a distal blood supply that would not be adequate in a single-stage procedure. This flap has an increased arc of rotation that may provide solutions to difficult reconstructive problems in the groin, lower abdomen, genitalia, knee, proximal leg, and might be suitable as a free flap.
