猪心表浅静脉观察

用大体解剖方法观察了５０例猪心表浅静脉，猪心冠关呈卵圆形，冠状窦瓣形态不一，多数（７６％）心中静脉直接注入右心房，猪心存在明显的右室后静脉，心前静脉包括升支和降低支两组。根据冠状窦的收受范围和心静脉的注入形式不同，将猪心表浅静脉分为６种类型。

An Observation on the pig Superfical Cardiac Veins

The morpholgical feature of the superficial cardiac veins wasinvestigated in 50pig hearts by gross dissection method.The ofifice ofthe coronary sinus was ovoid,the valves at the orifice of soronarysinus were variable in form and dimension.Almost 76% middle cardiacvein opened directoy into the right atrium.The posterior rightentriculary vein of the pig hearts was obvious.Anterior cardiac veinsincluded ascending and descending tributary groups.According to thedistribution pattems of the tributaries of coronary sinus and the formsof the venous opening,the cardiac vein mightbe divided into 6 types.
