Assessment of intraparenchymal lung collateral ventilation.
We read with interest the paper of Marshall et al entitled 'Direct visualisation of collateral ventilation in COPD with hyper-polarised gas MRI'. 1 Collateral ventilation (CV) is defined as 'the ventilation of alveolar structures through passages that bypass the normal airway'. 2 This happens through the intra-alveolar pores of Kohn, the bronchio-loalveolar communications of Lambert and the int...
متن کاملPredicting atelectasis by assessment of collateral ventilation prior to endobronchial lung volume reduction: a feasibility study.
BACKGROUND The advent of endoscopic lung volume reduction (ELVR), especially relying on valve technology to achieve atelectasis, has aroused new interest in the assessment of collateral ventilation, which has been implicated in ELVR failures. We are reporting on the use of a catheter-based device that measures airway pressures and flows, and calculates airway resistance in vivo. OBJECTIVES To...
متن کاملCorrelation between collateral ventilation and interlobar lung fissures.
BACKGROUND New bronchoscopic techniques for end-stage emphysema treatment are nowadays available; the presence of interlobar collateral ventilation (CV) and interlobar lung fissures (ILF) is crucial for patient selection. OBJECTIVES Assessment of these variables has been reported previously, but it has never been anatomically validated in vivo. This is the purpose of our study. METHODS Twen...
متن کاملAuthor's response to reviews Title: Effect of low tidal volume ventilation on lung function and inflammation in mice Authors:
The Conclusion has to concentrate more on the major results in respect to VILI. Formation of atelectasis is an important factor but there were no data presented in the study. Also the oxygenation data are important. Most of the animals were hypoxic in a different degree but how hypoxia influenced VILI was not the hypothesis of the study. There was no significant difference in oxygen saturation ...
متن کاملCollateral damage assessment for endobronchial lung volume reduction.
LUNG VOLUME REDUCTION SURGERY improves symptoms, lung function, and mortality in selected groups of patient with advanced emphysema (5). However, the uncertainty of individual outcomes and associated morbidity and mortality has limited utilization of this major surgical procedure. There is substantial interest in potentially safer, nonsurgical alternatives. Many of these methods attempt to make...
