摘　　要：目的 探讨家猪心血管三角的解剖结构,为建立动物模型提供形态学数据.方法 选购形态结构完整的家猪心脏50例,大体观测心大静脉和左冠状动脉及其分支的位置、数目、外径和角度.分析心血管三角的特点.结果 家猪心血管三角可分为相交、相伴和复合三种类型.在三角形中,前室间支与左旋支构成的角为97.0±15.4°,对应边长为46.24±15.30 mm;前室间支与心大静脉构成的角为29.7±10.3°,对应边长为23.50±8.02 mm;左旋支与心大静脉构成的角为54.9±16.4°,对应边长为36.30±13.94 mm.心血管三角内可有左室前支和对角支走行.结论 家猪心血管三角形态与人心相似,大小有显著差异.家猪可作为冠心病和冠状窦介入治疗的良好动物模型.Objective To explore the anatomic structure of pig cardiac blood vessel triangle and provide anatomic data for animal models. Methods Fifty intact pig hearts were dissected to measure the location, quantity, outer diameter and angle of left coronary artery and its branches, as well as great cardiac vein and its tributaries. The characteristics of cardiac blood vessel triangle were analysed. Results The cardiac blood vessel triangle could be divided into intersectant type, associated type and complex type. In the triangle, the included angle consisting of anterior interventricular branch and circumflex branch was 97.0±15.4, whose corresponding side length was 46.24±15.30 mm; the included angle consisting of anterior interventricular branch and great cardiac vein was 29.7±10.3, whose corre- sponding side length was 23.50±8.02 mm ; the included angle consisting of circumflex branch and great cardiac vein was 54.9±16.4, whose corresponding side length was 36.30±13.94 mm. There could be anterior branches of left ventricle and opposite angie branches in the triangle. Conclusions Pig cardiac blood vessel triangle is similar to that of human in form, but distinctly different in size. The pig can be used as excellent animal models for interventional treatments of coronary heart disease and coronary sinus.
