心脏微循环血管的扫描电镜观察 Ⅰ.心脏血管球

SCANNING ELECTRON MICROSCOPIC OBSERVATION ON CARDIAC MICROCIRCULATORY BLOOD VESSELS(I)——VASCULAR BALLS OF HUMAN HEART

应用血管铸型、扫描电镜观察方法,研究了2例成人及1例儿童的左冠状动脉前降支中段心肌浅层及其周围的脂肪组织内的心脏血管球的三维构筑.根据形态特点,将心脏血管球分为圆球型、柱型、多角型、捆绑型、绒团型及鸭梨型,并对各型心脏血管球的形态结构特点进行了描述,且阐述了这些心脏血管球的临床意义.

The three dimensional architecture of cardiac vascular balls in the superfacial cardiac muscle and the adipocellular layer around the middle segment of anterior interventricular branches of the left coronary artery of two adults and one child was studied by vascular casts and scanning electron microscopy According to their morphological features,cardiac vascular balls were classified as round ball-like.cylinder-like,multiple angle-like,tied-up-like,floccule-like,and pear-like.In this paper,we not only discribe the morphological and structural features of each kind of cardiac vascular balls,but also illustrate the clinical significance of these cardiac vascular balls.
