为探讨膈褶与肝副裂的形态特征，明确其临床意义，本文观测了２９例常规固定成年男尸以及５０例２７—３８周胎儿肝和膈。并对３例膈褶和附近膈组织进行了切片观察。结果：（１）５０例胎儿未见肝副裂和膈褶；（２）３例成年肝有肝副裂与膈褶并存；（３）膈褶中有１—３条较大血管，其血管截面积大于无褶膈中血管截面积；（４）膈褶的骨骼肌组织厚于无褶膈者。本文认为膈褶可能与局部大血管有关，与长期慢性咳嗽、有力的膈肌运动等产生的“机械”因素有关。肝副裂可能为外力型。就膈褶与肝副裂的形态特征提出临床注意要点。
In order to explore the morphological features of the phrenic pleura and liver paratsupae and to clarify its clinical significance, we observed 29 cases of routinely fixed adult male corpses and 50 cases of fetal liver and diaphragm in 27-38 weeks. Three cases of septal pleura and adjacent diaphragmatic tissue were observed. Results: (1) There were no liver cleft palate and phrenic pleura in 50 fetuses. (2) There were 3 adult hepatic paraconeal fissures and phrenic pleuroses in 3 adult fetuses. (3) There were 1-3 larger vessels in phrenic folds, The cross-sectional area is larger than the cross-sectional area of blood vessels in the non-pleated diaphragm. (4) The skeletal muscle tissue of phrenic pleura is thicker than those without pleated diaphragms. This paper suggests that septum may be related to the local macrovascular, and long-term chronic cough, vigorous diaphragm movement and other “mechanical” factors. Liver cleft may be external force type. On the shape of pleural folds and liver cleft morphological features of the clinical points.
