OBJECTIVE: The site of cannulation for the repair of ascending @entity1580 remains controversial. It is not clear whether cannulation of the dissected vessel is safe or even preferred. We hypothesized that cannulation of the dissected aorta could be done safely with acceptable complication and mortality rates in this high-risk population. METHODS: The charts of repairs of acute ascending @entity1580 (n = 70) from 1996 to 2005 were reviewed. Cannulation was accomplished in 24 @entity1 via the dissected aorta (central) and in 46 @entity1 through cannulation of the femoral or axillary artery (peripheral). All were converted to sidearm cannulation of the graft for reperfusion. Groups were compared on the basis of comorbidities in addition to mortality, complications, hospital stays and final disposition. RESULTS: The groups were comparable on the basis of age and preoperative comorbidities. Similarly, there were no differences in bypass time, crossclamp time, or hypothermic circulatory arrest time between groups. @entity260 , including @entity64 , were similar between groups, but the peripheral group experienced more @entity299 (peripheral 15% vs central 0%; P < .05) and higher mortality than the central group (peripheral 19.5% vs central 4.2%; P < .05). CONCLUSIONS: Direct cannulation of the dissected aorta was safe compared with peripheral cannulation in these @entity1 . Inasmuch as these data demonstrate that cannulation of the dissected ascending aorta is safe, this technique can be used to tailor the cannulation approach to specific anatomic and @entity1 characteristics that might optimize postoperative outcomes in this disease entity.

Central cannulation is safe in acute XXXX repair.
