Prediction of Postoperative Pulmonary Function Following Thoracic Operations - Perfusion Lung Scanning Method -
폐관류스캔에 의한 폐절제술후 폐기능 예측
Abstract
The purpose of this study is to predict postoperative lung function by perfusion lung scanning method. 40 patients who underwent lobectomy or pneumonectomy between 1983-1985 were analyzed. Mean preoperative FEV1 was 2.36 L in lobectomy cases and 1.73 L in pneumonectomy cases. Preoperative and postoperative lung function were measured by routine spirometry in sitting position. Perfusion lung scanning was performed by 99mTc-MAA radioisotope. Postoperative FEV1 and VC were predicted by the formula; Postoperative FEV1 [VC]=Preoperative FEV1 [VC] x percent function of regions of lung not to be resected. In this study, I concluded that perfusion lung scanning is a simple and useful method to predict postoperative ventilatory function after pneumonectomy of lobectomy.
