Fig. 3From: Cellular and acellular ex vivo lung perfusion preserve functional lung ultrastructure in a large animal model: a stereological studySome sections contained areas with microatelectasis or oedema formation. Microatelectasis was seen predominantly in control group (a) or ischaemia group (b). Oedema was found almost only in EVLP groups (c) aEVLP, (d) cEVLP).
