本文用透明,软X线造影及组织学切片技术,对100例家兔左心室壁内动脉进行了观察,并与人心左室壁内动脉作了比较讨论。家兔左心室壁内动脉的分布类型在许多方面与人相似。分支型动脉(classA血管)供应心肌全层,包括心内膜下层;直型动脉(class B血管)主要分布到乳头肌、肉柱。乳头肌内动脉分布可分为节段型、轴型和混合型。室间隔壁内动脉的分布比较紊乱,无明显规律。在心脏横切面中,毛细血管互相吻合成网,其走行方向与心肌纤维方向一致。
In this paper, 100 cases of rabbit left ventricular intra-arteries were observed with transparent, soft X-ray and histological sections technology, and compared with the left ventricular artery in human heart. The distribution of rabbit left ventricular wall arteries is similar in many ways to humans. Branched arteries (class A blood vessels) supply the entire myocardium, including the subendocardial layer. Straight arteries (class B blood vessels) are mainly distributed in the papillary muscles and meat pillars. Papillary intramuscular artery distribution can be divided into segment type, shaft type and hybrid type. Interventricular septal artery distribution more disorder, no obvious law. In the cross-section of the heart, capillary mutual anastomosis into a network, its direction of travel consistent with the direction of myocardial fibers.
