RATIONALE AND OBJECTIVES
Some septal structures have been observed in the areas of incomplete interlobar fissures (IIFs) in resected lungs. We describe the anatomy of IIFs with or without the presence of septal structures.
METHODS
Twenty fused areas from 16 autopsy cases were examined histologically. Other septal structures outside the areas of IIFs also were examined.
RESULTS
In 10 of the 20 fused areas, there was a mixture of septal structures with and without defects. In the remaining 10, there were no septal structures. The septal structures consisted of two inner layers from both lobes. Other septal structures examined were the same as ones observed in the IIFs.
CONCLUSION
Linear shadows seen at interlobar fissures and on computed tomography scans do not necessarily depict the presence of complete interlobar fissures. The absence of linear shadows does not necessarily imply the absence of septal structures.
原理与目的
在切除的肺脏中，已在不完全叶间裂（IIF）区域观察到一些间隔结构。我们描述了有或无间隔结构的IIF的解剖结构。
方法
对16例尸检病例的20个融合区域进行组织学检查。还检查了IIF区域外的其他间隔结构。
结果
在20个融合区域中的10个，存在有缺陷和无缺陷的间隔结构混合情况。其余10个区域没有间隔结构。间隔结构由来自两个肺叶的两层内层组成。检查的其他间隔结构与在IIF中观察到的相同。
结论
在叶间裂处和计算机断层扫描上看到的线性阴影不一定表示存在完整的叶间裂。没有线性阴影不一定意味着没有间隔结构。
