Clinic anatomy and design of island skin flap in the lower leg / 基础医学与临床

ABSTRACT

Objective To study the blood supply of the flap accompanying vessels of the cutaneous nerves in the lower leg, and to design the reversed flap for clinical reference. Methods Anatomic observation was performed on 30 adults’ lower extremity specimens perfused via pressure with red latex through femoral arteries. Results Superficial peroneal nerves, sural nerves and saphenous nerves were all nourished by their accompanying arteries which, anastomosed with the cutaneous perforating branches of other arteries, also nourish the corresponding skin areas. Conclusion The blood supply of the reversed island flap accompanying vessels of the cutaneous nerves in the lower leg is reliable and so it is possible to design long flaps along the cutaneous nervous axis.
