A total of 10 adult, healthy, male chinchillas (Chinchilla lanigera) were used to investigate the origin, course, and termination of the coronary arteries. Coloured latex was injected into the carotid arteries following conventional anatomical applications. In all the chinchillas examined, the left coronary artery was the single coronary artery. The right coronary artery was missing. Additionally, a small vessel originating from the cranial border of the aorta was observed in one chinchilla. The left coronary artery divided into the paraconal, interventricular and left circumflex rami. The left marginis ventricular ramus arose from the paraconal interventricular ramus in eight chinchillas, and from the left circumflex ramus in two. The ventricular and septal branches of the left coronary artery ran subepicardially at the beginning mostly parallel to the muscle fibres, also surrounded by a thin adipose tissue. It was concluded that the only left coroner artery supplied blood to the heart in the chinchilla.
总共使用了10只成年、健康的雄性毛丝鼠(Chinchilla lanigera)来研究冠状动脉的起源、走行和终末。按照传统解剖方法将彩色乳胶注入颈动脉。在所有检查的毛丝鼠中,左冠状动脉是唯一的冠状动脉,右冠状动脉缺失。此外,在1只毛丝鼠中观察到一条起自主动脉头侧缘的小血管。左冠状动脉分为圆锥旁支、室间支和左旋支。左缘室支在8只毛丝鼠中起自圆锥旁室间支,在2只毛丝鼠中起自左旋支。左冠状动脉的室支和间隔支起初在心外膜下走行,大多与肌纤维平行,也被一层薄的脂肪组织包绕。得出的结论是,在毛丝鼠中,仅左冠状动脉为心脏供血。
