Sequential Endoscopic Lung Volume Reduction

August 30, 2022 updated by: Felix JF Herth, Heidelberg University

Sequential Endoscopic Lung Volume Reduction in Patients With Heterogeneous Lung Emphysema

Patients with heterogenous emphysema benefits from endoscopic lung volume reduction. Until now the technique is limited to one lobe. In case of collateral ventilation patients show no improvement. Between upper and middle lobe exists the highest collateral flow. The trial examine the hypothesis, that sequential ELVR help especially those patients, which have no benefit after lobar exclusion.
