title: [Hemoptysis one year after video-assisted thoracoscopic bullectomy for spontaneous pneumothorax: report of a case].
abstract: A 63-year-old man who had underwent video-assisted thoracoscopic bullectomy for left spontaneous pneumothorax 1 year before developed recurrent hemoptysis. Chest computed tomography showed previous stapling of the subsegmental bronchus in the left apico-posterior segment Bronchial arteriography showed hypervascularization of bronchial artery in the left upper segment and pooling of contrast medium along the staple-suture line. Video-assisted thoracoscopic apico-posterior segmentectomy was performed successfully. Pathological examination revieled hemosiderin lining along the surgical stump of B(1+2)cii, neither with infection nor infarction. These findings suggest that mechanical stapling of B(1+2)cii induced ischemia in the peripheral lung parenchyma causing bronchial hypervascularization. Late onset hemoptysis should be kept in mind as a complication after bullectomy with a mechanical stapler.
