　　Objective To investigate the three-dimensional construction and preservation of coronary anatomy in miniature pig hearts.

　　Methods Five complete fresh Guangxi Bama mini-pig hearts were selected as experimental objects, and the coronary arteries of mini-pig hearts were made by perfusion and corrosion. The production process of the casting model and its three-dimensional three-dimensional model.

　　Results The cast-embedded model of the mini-pig heart coronary artery had high transparency, and the course and branch distribution of the coronary vessels of the mini-pig heart could be clearly observed, and no cast branches were broken. The three-dimensional model constructed the anatomical structure of the mini-pig heart coronary artery. , Strong three-dimensional sense, no artifacts, can be rotated and divided at any angle in three-dimensional space.

　　Conclusion The crystal-embedded cast model can effectively protect the coronary cast specimens of miniature pig hearts, and its three-dimensional model can also provide a technical and empirical basis for the study of three-dimensional virtual simulation of blood vessels in animal models.
