本文采用冠状动脉X线造影法、解剖法和腐蚀法研究了14例成人心脏室间隔的动脉及其吻合。供应室间隔的动脉有前中隔动脉,后中隔动脉,房室结动脉,后上中隔动脉和降隔动脉。左、右冠状动脉在室间隔的供应范围分别占40～98％和2～40％。室间隔动脉不仅在室间隔形成丰富的冠状动脉内吻合和冠状动脉间吻合,它们还可与其它动脉吻合于房间隔,心房后壁,动脉圆锥部,心尖部和后室间沟。本文还观察了正常人和心脏病患者室间隔动脉吻合支的形态特点和直径。
In this paper, coronary arteries and their anastomosis were studied in 14 adult patients with interventricular septum by means of coronary angiography, anatomy and erosion. The arteries supplying the interventricular septum include anterior septal artery, posterior septal artery, atrioventricular node artery, posterior superior septal artery and descending septal artery. Left and right coronary artery in the supply of ventricular septal area accounted for 40 ~ 98% and 2 ~ 40%. The interventricular septum not only produces abundant intracoronary and intercoronary anastomoses at the septum but also interacts with other arteries in the atrial septum, posterior atrial wall, arterial conus, apex, and posterior interventricular groove. This article also observed the morphological characteristics and diameter of anastomosis branch of the interventricular septum in normal subjects and patients with heart disease.
