The presence of interlobar<unk>  will affect the choice of lung volume reduction procedure that may be offered in severe cases of emphysema. Emphysema usually develops in later years from the breakdown of alveolar walls resulting in much larger airspaces and much larger pathways for a preferential route of<unk> . Ageing can alter the size of the pores of Kohn, further reducing the normal resistance of the<unk>  pathways. In lung volume reduction procedures interlobular<unk>  is a major factor that can affect a successful outcome. A study showed that those with emphysema had a ten-fold increase of<unk>  over healthy controls. The intent of lung volume reduction is to achieve the complete collapse (atelectasis) of an entire lobe of the lung in order to reduce volume in the chest, restore elastic recoil and improve breathing. Interlobar<unk>  can prevent this. Incomplete lung fissures that separate the lobes of the lung are fairly common and usually without consequence. These fissures are often bridged by parenchyma connecting the airspaces of one lobe with those of another and therefore providing a path for<unk> . This type of parenchymal bridging would prevent the intended collapse of a targeted lobe. Interlobar<unk>  precludes the bronchoscopic procedure that uses endobronchial valves.
