Endobronchial Valve

Patients with prolonged air leak or bronchopleural fistula after lung resection may benefit from placement of endobronchial valve.  IBV Valve System has been developed by Spiration to control prolonged air leaks of the lung following lobectomy, segmentectomy or lung volume reduction surgery.  Patients with prolonged air leak can be treated with prolonged use of chest tube or redo-operation.  IBV Valve system is an alternative for these patients.  It is used for patients who has air leak present on post-operative day 7.  IBV Valve System is placed for 6 weeks to treat prolonged air leak.


The procedure is performed in the operating room.  The patient will have general anesthesia with placement of endotracheal tube.  A flexible bronchoscope is inserted through the tube.  Next we will determine the location of the air leak by inflating a small balloon in the airway.  After the airway is identified, we will place a smaller balloon to determine the correct size valve.  Finally, a valve will be implanted in that airway to minimize the leak.


The rare risk of the operation include irritation of the airway, bronchitis, pneumonia, persistent cough or development of shortness of breath.  The risks of having the bronchial valve are that it may become loose and you may cough it out of your lung.  The valve can cause irritation or swelling of the airway and development of bronchitis or pneumonia.  You may have cough from having the valve.  You may develop bleeding from having the bronchial valve.


This can be performed as an outpatient procedure.

Longterm Outcome

The IBV Valve System have been shown to decrease duration of the chest tube in patients with persistent air leak.
