What major operative modifications of the original Bentall composite graft procedure are being used at Johns Hopkins?
We currently prefer to use the coronary button technique for virtually all of our patients receiving a composite graft. Normally, the aortic buttons have a diameter of 12 to 15 mm and we like to use an overlaying washer of Teflon felt to buttress the suture line. We use 4-0 polypropylene suture for anastomosis of the coronary button to the Dacron graft. We also use a narrow strip of Teflon felt to buttress the distal suture line, which can be carried out either with 4-0 or 3-0 polypropylene suture. As Kouchoukos first pointed out in 1986, it is important not to construct a blood-tight closure of the residual aneurysm wall over the composite graft. With this modification of the original Bentall procedure, the complication of coronary artery dehiscence has been virtually eliminated.
