Background: In surgical graft replacement of the descending aorta graft, one-lung ventilation (OLV) is required to provide adequate surgical view and to allow removal of blood from the left lung. It is best to use a double-lumen tube (DLT) to assure OLV, but it is sometimes difficult to place the left-sided DLT due to thoracic aneurysm or the dissection lumen. We retrospectively investigated tracheobronchial anatomy by chest X-ray and chest computed tomography (CT) in 29 cases of descending aorta replacement to determine how best to manage difficult placement of the left-sided DLT. Methods: From our database of 29 patients who had undergone descending aorta replacement between February 1, 2005, and December 31, 2009, we investigated the association between difficulty in placing the left-sided DLT and tracheobronchial anatomy by chest X-ray and CT. Results: We could not place a left-sided DLT in 3 of 29 cases. Two of these cases were planned surgery for aortic aneurysm and the other was an emergency operation for acute aortic dissection. We could manage the two cases safely using a right-sided DLT. We compared chest X-ray and chest CT images of these 3 cases with the other 26 cases and found that compression of the tracheobronchial tree was prevalent in the cases of difficult placement of the left-sided DLT. Conclusions: We experienced difficulty in placement of the left-sided DLT in 3 of 29 cases of descending aorta replacement. We can predict difficulty of left-sided DLT placement by the presence of compression of the tracheobronchial tree on chest CT. Source
