Digital anatomical study of perforator flap based on the perforating arteries of profunda femoris artery in vivo
Objective To explore the feasibility of three-dimensional visualization of the profunda femoris artery perforator flap and provide the anatomical data for clinical application of profunda femoris artery perforator flap. Methods A series of DICOM images were obtained from eight patients by DSA and dual source CTA. Then Mimics 16.0 was used for three-dimensional reconstruction of perforating artery and perforators of profunda femoris arteryies. Results The 3D visualization models of perforating arteries of the profunda femoris artery and their perforators could be successfully achieved by using Mimics. The 3D reconstruction models showed variable origin, location, presence, volume and course of the profundafemoris artery, perforating arteries as well as their perforators clearly. Three perforating arteries which derived from the profunda femoris artery were found in six patients and four perforating arteries displayed in two patients. 66 cutaneous perforators (>0.5 mm) have been found in the eight patients. The average internal diameter of perforator was (0.9±0.2) mm. Cutaneous perforators can be found on a line extending from the ischium to the lateral femoral condyle. Conclusion The 3D reconstruction models can provide perfect dynamic visualization of perforating arteries of profunda femoris artery and their perforators. It can provide the anatomical basis for clinical application of perforator flap base on perforating arteries of profunda femoris artery, and may be used for its individualized design.
