title: [Evaluation of postoperative pulmonary complications and remaining pulmonary arterial flow of lobectomized lung cancer patients using pulmonary digital subtraction angiography].
abstract: Postoperative pulmonary complications cause the decrease of the flow of remaining pulmonary circulation. We examined the effects of the difference of resected lobes on the postoperative course and remaining pulmonary circulation of the lobectomized lung cancer patients using a pulmonary digital subtraction angiography. In all cases with preoperative pulmonary complications, circulatory flow of the remaining lung on the operated side significantly decreased. In the cases without preoperative pulmonary complications, only the cases performed left upper lobectomy developed the decrease of the circulatory flow on the operated side. This seemed to be chiefly caused by a postoperative continual atelectasis of the remaining lower lobe due to kinking of the bronchus. On the other hand, the postoperative decrease of the residual pulmonary circulatory flow on the operated side was not developed in the cases undergoing a segmentectomy, even with pulmonary complications. Therefore, for any case requiring a left upper lobectomy or the case with an impaired lung requiring any type of lobectomy, contralateral pulmonary function should be exactly evaluated preoperatively.
