Use of an Interposition Tube Graft for the Reattachment of Left Coronary Ostium to the Aortic Composite Valve Graft -One Case-

Abstract
|
|
|
The usual methods for the re-attachment of coronary ostia to the ascending aortic conduit have several disadvantages and potential complicatins. A novel, straight forward technique is described that allows for tension free anastomoses to be
constructed
with minimal risk of blood loss and a reduced risk of a 40-yrs-old male patient of acute aortic dissection(Stanford Type A, DeBakey Type I) with severe aortic regurgitation. The techinque comprised anastomosis of a beveled interposition tube
graft
to
the left main coronary artery ostium, and its proximal anastomosis to the ascending aortic graft after seating the composite valve graft in the prepared aortic annulus. With this technique, the low-lying or distant left main coronary ostium can
be
easily reattached to the ascending conduit without undue tension.
