摘　　要：目的：从发生学角度探讨心肌血管重建术的供血机理。方法：本文采用不同胎龄的人胎心１３个，用墨汁灌注血管、组织切片染色法，观测左心室壁与心腔的血管交通状况。结果：显示人类胚胎早期的心脏，心室壁结构类似海绵状，心腔与心壁间存在着许多窦状通道。这类管道包括肉柱间隙、心肌窦样管等，其排列、配布及在心室壁的分布范围随着胎儿生长、结构重建而不断变化。其胚胎发育过程重复了种系发生的各个阶段。结论：提示激光心肌血管重建术从心腔直接供血，与人胚早期者相类似。Objective:To Study the mechanism of myocardial reascularization from the aspect of embryology.Methods:The coronary arteries of 13 fetal hearts aged various months were perfused with Chinese ink.Histological sections were made to study communications between the left ventricular wall and the chamber under microscope.Results:The ventricular wall was built like the spongy structure with many communicating channels with the chamber.The arrangement,distribution and relative proportion of these channels including intertrabecular spaces and myocardial sinusoids underwent remarkable changes during appositional growth and strucural reconstruction.It showed that fetus repeated certain stages of phylogenesis in its ontogenesis.Conclusions:Direct myocardial revascularization by laser was similar to the mode of bringing blood from heart cavity into the myocardium in early period of fetal heart.
