Decortication was done for those cases in which lung expansion was not obtained within 10 to 12 days following intercostal chest tube drainage, antibiotherapy based on sensitivity tests of pleural fluid and pleural irrigation.
Preoperatively, CT scan and sinogram for the determining the size of pleural pouche were carried out and pulmonary perfusion sintigrams with Tc99 labelled maroaggregated albumin (MAA) to prove perfusion of the involved lung in 23 patients with mean 65 % perfusion loss were taken.
Postoperatively, perfusion defect of ten patients was found to be decreased below mean 4% in approximately third month. Average postoperative hospitalization stay lasted ten days.
