摘　　要：目的探索猪股骨头标本离体后支持带动脉显微灌注技术方法。方法显微镜下对12例离体猪股骨头标本显微灌注,显微CT扫描;血管三维重建。结果通过下支持带动脉对离体猪股骨头显微灌注及骨内血管三维重建。构建离体股骨头的数字化三维模型,可精确、清晰呈现股骨头内动脉主干及其分支的形态结构。结论离体猪股骨头动脉显微灌注及骨内血管三维重建能够清晰显示猪股骨头骨内的血管。为股骨头缺血性坏死研究提供形态学基础。Objective To investigate the feasibility of pig femoral head micro perfusion and quantitative analysis of the intraosseous artery. Methods 12 pig femoral head specimens were perfused using contrast agent of gelatin barium sulfate suspension under surgical microscope. After micro CT scanning, the intraosseous artery three-dimensional digital model was reconstructed. Results Micro perfusion and quantitative analysis of the pig in vitro femoral head intraosseous artery is possible. The reconstructed model is accurate, high resolution, which also contains artery structure, bone mass, and bone structure. Conclusion Micro perfusion of femoral head and quantitative analysis of the in vitro pig femoral head intraosseous artery provide a research technique to study the intraosseous artery morphology for study of femoral head avascular necrosis.
