    Abstract:
    We address 3 important keys to obtain successful outcomes in surgery for emphysematous giant bullae. It is the 1st step to select patients who might benefit from bullectomy based on functional imaging. The chest computed tomography (CT) and pulmonary perfusion scintigram provide information regarding with pulmonary vascular beds which could be recruited by bullectomy. In addition, dynamic-magnetic resonance imaging (MRI) during breathing can show a patient with paradoxical inflation of giant bulla during expiration, which means impairment of ventilation of the adjacent normal parenchyma, and is a promising sign for successful outcome of bullectomy. Second, it should be emphasized to perform a proper procedure in bullectomy. If a giant bulla has a wide bottom, it should be recommended to open the bulla and to plicate it by sutures without injury of vessels on the bottom of the bulla rather than simple bullectomy with staples. Finally, it is important to keep inflated lung avoiding atelectasis following operation by minimum pressure of suction. We show here sequential bullectomies on a 41-year-old male with chronic obstructive pulmonary disease (COPD) GOLD IV due to bilateral giant bullae and poor vascular reserve, and address our strategy described above.
