摘　　要：目的对穿支体区血管及其相互间的吻合情况进行综合分析,为穿支皮瓣的应用提供解剖学依据。方法使用改良的明胶--氧化铅血管造影技术,灌注新鲜尸体标本10具。使用螺旋CT进行扫描并通过相应的软件存储扫描得到的图像,选择下腹部和小腿外侧皮瓣供区,应用交互式的医学影像控制系统(Mimics)进行3D可视化研究。结果三维重建的各部位层次分明、穿支体区间小血管的清晰度好,穿支体区间的血管吻合有3种类型,2个层次。而且可对不同层次分别进行透明、不同穿支体分别配色或提取等专业化处理。结论①应用Mimics可以非常方便地对穿支体区及其相互间血管的吻合情况进行综合分析;②穿支皮瓣血供方式与传统轴型皮瓣有异。Objective To determine anatomical characters of the perforasome and its choke vessels by using angiography in cadavers and software system MIMICS.Methods 10 fresh cadavers were subjected to angiography and CT scan,and reconstructed in three dimensions.Focus was placed on the generation of digitalize visual model of inferior abdominal and the lateral peroneal region.Specimens were then dissected by layers to document the individual perforasomes.Results The layers of the anatomical model were distinctively displayed;the small blood vessels between adjoining perforator were illustrated in high clarity.The choke vessels between the neighboring perforators can be divided into three types,located among two layers.In addition through the program we can perform specialize application such as,transparency to each layer,labeling each perforator with different color and digitalize flap elevation stimulation.Conclusions ①Through the use of Mimics integrative vascular analysis can be performed on the perforators and its choke vessels,therefore providing useful data such as vascular anatomy and its distribution,this could be of clinical significance and enables better understanding of perforator flaps.② Blood supply of perforator flap is difference with the traditional axis flap.
