Thin-section computed tomographic scans of both lungs in 154 patients, including seven cadavers, with lung cancer (n = 37), diffuse (n = 32) or inflammatory (n = 30) lung disease, other proved or suspected disease (n = 23), or healthy lungs (n = 32) were analyzed to determine the frequency of incomplete interlobar fissure (IIF). An IIF was defined as a discontinuous linear shadow that remained in contact with the chest wall. An IIF was found in 128 of 154 right lungs (83.1%) and 77 of 154 left lungs (50.0%). Some bronchovascular structures crossed or passed through two contiguous lobes in the fused area. The most common bronchovascular structure associated with an IIF was a pulmonary vein; this association was found in 87 right lungs (56.5%) and 20 left lungs (13.0%). An IIF was traversed by a pulmonary artery in only seven right lungs and 13 left lungs or by a bronchus in only three lungs. It is concluded that recognition of an IIF might improve understanding of the spread of pulmonary disease.
对154例患者（包括7例尸体）的双肺进行薄层计算机断层扫描，这些患者患有肺癌（n = 37）、弥漫性（n = 32）或炎性（n = 30）肺部疾病、其他已证实或疑似疾病（n = 23）或健康肺（n = 32），以确定不完全叶间裂（IIF）的发生率。IIF被定义为与胸壁保持接触的不连续线性阴影。在154个右肺中的128个（83.1%）和154个左肺中的77个（50.0%）发现了IIF。一些支气管血管结构在融合区域穿过或经过两个相邻的肺叶。与IIF相关的最常见支气管血管结构是肺静脉；在87个右肺（56.5%）和20个左肺（13.0%）中发现了这种关联。只有7个右肺和13个左肺的IIF被肺动脉穿过，只有3个肺的IIF被支气管穿过。结论是，认识IIF可能有助于提高对肺部疾病传播的理解。
