Preoperative balloon sealing of a false ascending aortic aneurysm for safe redo sternotomy.

Sternal contact of aortic aneurysms in redo operations may require specific techniques to safely control bleeding during sternotomy and surgical dissection. This is the first report on the preoperative use of an inflatable balloon to prevent massive hemorrhage by inserting the balloon--a procedure performed in the cardiac catheterization laboratory--before rethoracotomy. A false ascending aortic aneurysm was successfully sealed by transaortic wire-guided balloon placement from the iliac artery. Gentle traction on the inflated balloon catheter, which was placed inside the false aneurysm, effectively sealed the entrance to the aneurysm. A straightforward median redo sternotomy procedure was subsequently performed without blood loss from the unavoidably opened aneurysm. My colleagues and I propose this technique for aneurysms of mycotic or anastomotic origin, which have an anatomically distinct entry channel.
