Abstract:
Objective:The three-dimensional(3D) reconstruction method of calf perforator vessel was explored to provide the basis for clinical safe and accurate harvesting of calf chain perforator flap.Methods:Gelatin-lead oxide is automatically perfused the femoral artery of 3 fresh adult lower limbs specimens. Data were collected after the CT scan of the full limb, 3D reconstruction of bones, arteries and their perforators was processed in Mimics Research 19.0 software. Dynamic display of vascular hierarchy and adjacent relationships by adjusting CT values. And show the anatomical region of each perforator artery in different colors, measure the feeding area of the single perforator using Scion Image software. The 3D printed calf bone and vascular model can be used for direct observation. The specimen anatomy was measured according to a perforator vessel parameter with an outer diameter of 0.5 mm through the deep fascia. The number of perforators, vessle pedicle length, and outer diameter were observed and statistically analyzed.Results:The digitized 3D reconstruction images can clearly show the 3D structured of the calf artery and perforator vessels and micro vessels, as well as the course, distribution characteristics of blood vessels, and the 3D relationship with adjacent structures. The printed 3D model visually observes the hierarchy of the perforator vessels and the anastomosis relationship between the perforators. 3 calf specimen arteries with perforator artery 22±4, vessel pedicle length (46.7±18.3) mm, outer diameter (0.8±0.3) mm, the average blood supply area of the single perforator (38.2±10.7) cm 2. Conclusion:The Mimics Research 19.0 software should be used to dynamically reconstruct the 3D structure of the branch vessel by adjusting the CT value, which improves the display effect of the perforator vessels. The 3D printing model makes the source, course, diameter and distribution range of the perforator vessels visually visible, which provides experimental support for the clinical construction of digital calf chain perforator flap harvest scheme for patients.
