The value of bronchography in the diagnosis of pulmmonary diseases, especially of bronchial diseases, is well known and bronchography is an essential procedure for evaluation of braonhial diseases. And by visualization of a selected bronchial tree, lobar or segemental, we can obtain roentgenorgrams of superior quality and of higher and sample for pathology and bacteriology can be obtained. And there is another therapeutic possibility of introducing drugs intrabronchially through the catheter. Authors introduce a simple new technique of selective bronchography which is a combination of transglottic intubation and Seldinger method. The technique is summerized as follows , 1. Anesthetize oral cavity, pharynx and larynx with 2 % lidocaine. 2. Under fluoroscopic control, Nelaton catheter is introduced over a wire mandarin, as authors previously reported. 3. After removal of wire mandarin, angiographic guide wires in inserted through the catheter into the trachea. 4. Then , the Nel ton catheter is withdrawn and is changed with preshaped angiogrpahic catheter, just as in introduction of catheter in arterigraphy. We carried out 18 cases of selective bronchography with this technique and selection of lobar, segemental and sugbsegmental bronchi was carried out without difficulty.
