Case ReportsDifficult placement of Univent tube blocker due to aberrant right subclavian artery aneurysm.
There have been few reports on aneurysms of the anomalous branch of the aortic arch. We present a rare case in which correct placement of the movable blocker of a Univent tube was difficult due to an aberrant right subclavian artery aneurysm. A 72-year-old man with a history of hypertension had manifested coughing and wheezing for four months prior to admission to our hospital. ⋯ Several methods of blocker placement, including those recommended in the manual attached to the product, were attempted without success. Finally, the trachea was intubated again using a Univent tube with the blocker tip bent manually, which permitted entrance of the blocker into the bronchus. Blocker placement should be modified to suit patients with a problem in the trachea or bronchi.
