[Improving function by decortication. Functional studies with particular evaluation of lung perfusion scintigraphy].
The study presents functional and scintigraphic lung perfusion measurements before and after decortication of 9 patients treated for chronic pleural empyema with special emphasis to changes in perfusion scintigraphy. Preoperatively, the average vital capacity was 60% and the average FEV1 was 65% of the predicted. Perfusion of the affected side showed an average reduction to 22%. After decortication all functional data showed an improvement (average VC 78.5%, average FEV1 79.5%) the percentage of lung perfusion having increased to a mean of 37.8%.
