先天性膈疝和膈膨升的病理研究

摘要

对10例先天性膈疝、5例膈膨升和27例正常婴幼儿尸体的膈作了病理研究,提供了详细的解剖数据.研究发现,正常膈在两侧的腰肋三角区都存在一个先天性的肌层薄弱区,有的则肌层完全缺如.这一部位及其三角形形态与先天性膈疝的好发部位及疝口形态是一致的.膈膨升除肌纤维完全缺如外,尚有粗大胶原纤维层的缺如.这样,对先天性膈疝和膈膨升的发病原因提出了一些解剖发育上的解释.%This article reported the autopsy and surgical pathological studies on 10 cases with congenital diaphragmic hernia (CDH) and 5 cases with diaphragmatic eventration (DE) and 27 cases of normal diaphragm.It was found that in both sides of the normal diaphragms,there is a week area,even no muscle fibers in some cases,at the tribonum lumbocostales where is just the common site of the CDH.In DE,there are practically no collagenous fibers.This may explain the cause of CDH and DE on its anatomical and developmental bases.
