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.
