A review of the anatomy of the interlobar fissures is based on a detailed study of 100 fixed and inflated lung specimens (50 right and 50 left lungs). The upper part of the fissural surface of the right lower lobe almost always faces in a slightly lateral direction and is usually concave; the lower part typically faces laterally but is usually convex. The upper part of the left major fissure also almost always faces laterally and is concave; but unlike the right side, the lower part usually faces medially and is convex. The minor fissure is typically oriented so that the anterior part is lower than the posterior part and the lateral margin is lower than the medial margin. Incompleteness of the fissures (fusion between lobes) is common; this study revealed a 70% incidence of fusion across the upper right major fissure, 47% across the lower right major fissure, 40% across the upper left major fissure, 46% across the lower left major fissure, and 94% across the minor fissure. The fissural complex is a term used to describe the variable anatomic relation of the major and minor fissures. Some comments are offered concerning fissural anatomy relative to collateral air drift, the visualization and position of interlobar fissures on chest radiographs, and the appearance of inferior interlobar fluid on the lateral radiograph.
对叶间裂解剖结构的回顾基于对100个固定并充气的肺标本（50个右肺和50个左肺）的详细研究。右下叶裂面的上部几乎总是略向外侧，通常呈凹形；下部通常朝向外，但通常呈凸形。左主裂的上部也几乎总是朝向外且呈凹形；但与右侧不同，下部通常朝内侧且呈凸形。小叶裂通常的走向是前部低于后部，外侧缘低于内侧缘。叶裂不完全（叶间融合）很常见；本研究显示右上叶主裂融合发生率为70%，右下叶主裂为47%，左上叶主裂为40%，左下叶主裂为46%，小叶裂为94%。叶裂复合体是一个用于描述主裂和小叶裂可变解剖关系的术语。文中还对叶裂解剖结构与侧支气流、胸部X线片上叶间裂的显示及位置，以及侧位X线片上叶间积液的表现进行了一些讨论。
