Two techniques to locate the dominant perforator vessels
Objective To provide morphology data that enable to locate perforator vessels and flap design. Methods Two fresh
unfixed corpses underwent whole body bismuth oxide and polyvinyl alcohol injection, and then scanned by spiral CT. The CT data
was imported into the Mimics imagine workstation to locate the dominant perforator and flap design by volume rendering and
dynamic reconstruction. Results Two methods were able to locate the perforator. Rapid direct volume rendering on perforator
vessel locating was rapider, but it was not good to show adjacent structures. The dynamic reconstruction method was used for
perforator locating and flap design, and also showed adjacent layers clearly with threshold adjustments. Conclusion Rapid direct
volume rendering is a quick and simple way to show the locating of the perforating branches of the source artery in various
parts. Dynamic reconstruction method is able to display the adjacent structures with multi colored forms.The best way to locating
perforators is combining these two methods. The results provide the morphological basis for designing and simulating the flap.
