| Abstract |
|
Anomalous right upper lobe bronchus takeoff from the trachea has been reported to occur in 1 of 250 otherwise normal patients. Difficulty with double-lumen tube(DLT) placement has been described previously and there are problems with Univent tube with the intention of using the bronchial blocker to achieve right lung collapse in this patient. In two cases, the fiberoptic bronchoscopic examination through Univent tube revealed a trifurcation, rather than the usual bifurcation, at the carina and revealed that the most rightward lumen was the right upper lobe bronchus and the middle lumen was the right middle and lower lobe bronchus.
The left lumen was the left main bronchus. So in one case, the Univent tube was withdrawn and DLT was reinserted. In the other case right lung collpase achieved with the inflation of cuff of bronchial blocker. One lung anesthesia was performed without any problem in these two cases. |
