整形外科临床常用的带血管游离皮瓣和肌皮瓣均有一定的局限性。作者设想,如能利用皮下众多的静脉网使静脉血管动脉化,向皮瓣提供营养,那么游离皮瓣来源会增多,也不会丧失供瓣区肌肉的功能。作者设计了一项动物实验以验证该设想。材料和方法家兔作为实验对象。家兔分为四组,每组五只。全麻下从耳软骨表面游离耳后皮瓣,皮瓣仅借中央动、静脉 Plastic surgery commonly used in clinical free flap and myocutaneous flap have some limitations. The authors hypothesize that if many subcutaneous venous networks are used to arteriorate the veins and provide nutrients to the flap, then the source of the free flap will increase, without losing the function of the lobar zone muscle. The authors designed an animal experiment to validate the idea. Materials and Methods Rabbits as experimental subjects. Rabbits were divided into four groups of five. Under general anesthesia free from the surface of the ear cartilage flap, the flap only by the central artery and vein
