What is Lung volume reduction surgery is used in the management of and explain in detail?
Lung volume reduction surgery (LVRS) reduce volume of lung in emphysema. Patients with upper lobe-predominant emphysema and a low post-rehabilitation exercise capacity are most likely to benefit from LVRS. Patients are excluded if they have significant pleural disease, a pulmonary aery systolic pressure >45 mmHg, extreme deconditioning, congestive hea failure, or other severe comorbid conditions. Patients with an FEV1 <20% of predicted and either diffusely distributed emphysema on CT scan or diffusing capacity of lung for carbon monoxide (DlCO) <20% of predicted have an increased moality rate after the procedure and thus are not candidates for LVRS.Ref: Harrison 19e pg: 1706
