穿支体区血管及其相互间吻合的3D可视化研究

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。

Three dimensional visualisation of perforasome and its choke vessels

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 di...
