“…The selected donors were then clinically evaluated and submitted to simple X-ray and computed tomography scan of the chest with volume measurement of lower lobes, together with electrocardiogram, Doppler echocardiogram, renal function tests, hepatic function tests and serology, as well as evaluation of pulmonary function using spirometry. (16)(17)(18) In order to analyze the bronchial tree, all potential donors were submitted to fiberoptic bronchoscopy, which, in one case, determined the choice of the side of the lobectomy. Also, for the 10 first transplantations, pulmonary arteriograms were performed in the donors on the side chosen for lobectomy, in order to identify alterations in the origin of the segmental arteries that might cause difficulties during surgery.…”
