肺组织切除后的肺部并发症可引起严重后果。本文就术前预测非小细胞肺癌术后肺部并发症的可能性进行了研究。 方法 全部患者术前均接受颅和全身CT、肺灌注闪烁扫描、骨扫描和肺量计测试。预测残存肺功能公式为:肺功能×(1-切除侧肺灌注比例×切除的肺段数/切除侧肺段总数)。手术指征为预测术后用力肺活量(FVC)>800ml/m~2或第1秒用力肺活量(FEV_1)>600ml/m~2。术后肺部并发症 Pulmonary complications after lung resection can cause serious consequences. This article studies the possibility of predicting postoperative pulmonary complications of non-small cell lung cancer. Methods All patients received preoperative and total body CT scans, pulmonary perfusion scintigraphy, bone scans, and spirometry tests. The formula for predicting residual lung function was: lung function × (1 - resection side lung perfusion ratio × number of resected lung segments / total number of resection side lung segments). Surgical indications were predictive postoperative forced vital capacity (FVC)> 800 ml/m 2 or forced vital capacity (FEV_1)> 600 ml/m 2 during the 1st second. Postoperative pulmonary complications
