皮血管的血供类型可分为:(1)直接皮血管,起自深部动脉干,不发肌支;(2)肌皮血管,起自供应肌肉的动脉,发出穿支和缘支;(3)动脉干网状血管,由动脉干发出许多细小皮支;(4)间接皮血管,发皮支经肌间隔或肌间隙至皮肤。本文描述了以此四种血供类型为基础的各类皮瓣的解剖学特点。 Blood vessels of the type of blood supply can be divided into: (1) direct skin vessels, from the deep arterial stem, no muscular branch; (2) musculocutaneous vascular, starting from the supply of muscle arteries, perforating branches and limbs; 3) Arterial reticular blood vessels, issued by the arterial stem a lot of small skin; (4) indirect skin vessels, the hair branch by muscle space or muscle space to the skin. This article describes the anatomic features of various types of flaps based on these four blood supply types.
