Evaluation of the Predictive Pulmonary Function After Pneumonectomy Using Perfusion Lung Scan

Abstract
|
|
|
Surgical resection of lung cancer or other disease is recently required in patients with severely impaired lung function resulting from chronic obstructive pulmonary disease or disease extension. So prediction of pulmonary function after lung
resection
is very important in thoracic surgeon. We studied the accuracy of the prediction of postoperative pulmonary function using perfusion lung scan with 99m technetium macroaggregated albumin in 22 patients who received the pneumonectomy.
@ES The linear regression line derived from correlation between predicting (X) and postoperative measured (Y) values of FEV1 and FVC in patients are as follows:
@EN 1) Y(ml)=0.713X+381 in FEV1 (r=0.719), (P<0.01)
2) Y(ml)=0.645X+556 in FVC (r=0.675), (P<0.01)
In conclusion, the perfusion lung scan is noninvasive and very accurate for predicting postpneumonectomy pulmonary function.
