Lung perfusion and ventilation computed tomography protocols
Before procedure and 12 weeks after procedure

Study Arms (1)
Endobronchial valve:
EXPERIMENTALEndobronchial valve (size 4.0 - 7.0 mm or 5.5 - 8.5 mm) insertion for target bronchi
Interventions
One-way endobronchial valves are placed in segmental bronchi of the most hyperinflated and least perfused lobe of the emphysematous lungs on computed tomography (CT). Before the procedure, we confirm that the target lobe has no collateral ventilation with other lobes using Chartis® System (Pulmonx, Inc. Redwood City, CA, USA).
Eligibility Criteria
You may qualify if:
- Age more than 40 and below 75
- Patients with smoking history and heterogenous emphysema on chest CT
- Advanced emphysema (FEV1/FVC \<70%, FEV1 of 15-45%, TLC \>100% and RV \>150% predicted)
- Persistent symptoms refractory to treatment
- PaCO2 \<50 mmHg and PaO2 \>45 mmHg
- Body mass index (BMI) ≤31.1 kg/m2 (men) or ≤32.3 kg/m2 (women)
- min walk distance \>140 m after pulmonary rehabilitation
You may not qualify if:
- Diffusing capacity (DLco) \<20% predicted
- Large bullae (exceed 5 cm)
- Alpha-1 antitrypsin deficiency
- History of thoracotomy
- Excessive sputum production (throughout the week)
- Severe pulmonary hypertension ( systolic pulmonary artery pressure ≥ 45mmHg, estimated from the peak velocity of a tricuspid regurgitant jet by doppler echocardiography)
- Acute respiratory infection
- Unstable angina, congestive heart failure, or acute myocardial infarction in 6 months
