Correlation 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 کاملEndobronchial Valves for Emphysema without Interlobar Collateral Ventilation.
BACKGROUND Bronchoscopic lung-volume reduction with the use of one-way endobronchial valves is a potential treatment for patients with severe emphysema. To date, the benefits have been modest but have been hypothesized to be much larger in patients without interlobar collateral ventilation than in those with collateral ventilation. METHODS We randomly assigned patients with severe emphysema a...
متن کاملThe fissure: interlobar collateral ventilation and implications for endoscopic therapy in emphysema
In patients with severe emphysema, bronchoscopic lung volume reduction using one-way valves is a promising therapeutic option to improve lung function and quality of life. The goal of this treatment is to achieve a complete lobar atelectasis. In a significant proportion of patients, this atelectasis cannot be achieved due to interlobar collateral ventilation. This collateral ventilation is gene...
متن کاملAssessment 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 کاملCorrelation between alveolar ventilation and electrical properties of lung parenchyma.
One key problem in modern medical imaging is linking measured data and actual physiological quantities. In this article we derive such a link between the electrical bioimpedance of lung parenchyma, which can be measured by electrical impedance tomography (EIT), and the magnitude of regional ventilation, a key to understanding lung mechanics and developing novel protective ventilation strategies...
