Objective To provide the skin vessels morphologie basis for perforating flap of the antero- lateral thigh(ALT).Methods Six sides lower limbs of adult fresh cadaver specimens perfused with lead oxide-gelatine mixture were used.Observe the peraforators of anterolateral thigh by dissection.The elevated tissue was radiographed by X-ray and MSCT-scanning.Computer techniques was used for the detection and 3D-reconstruction of the regions of each perforators of ALT flap.Results The three-dimensional recostruct- ed digitized visible models perfectly displayed the anatomic structures of arteries on the anterolateral thigh, and,the morphology and distribution of the vascular territory of each perforator from descending branch of LCFA was displayed in the images of 3D-visualization,their effective morphology and distribution were same, and they accord with vascular territory of radiograph.On the 2D-image of X-ray,The margins of the anatomical distribution of each perforator from descending branch of the lateral circumflex femoral artery were determined, their total areas was about 25cm×24cm.Conclusion Since the digitized image of perforator territory can accord with the morphology of anatomy,and can off vascular structure insights into cutaneous perforator anato- my,their 3D visualizative models can be applied in pre-operative designing and virtual operation procedures, and can be helped for study of perforator flap.
