Wrapping procedure for stanford type a acute aortic dissection: is there an indication for surgery without a cardiopulmonary bypass?

A wrapping procedure for acute type A aortic dissection was performed on six elderly patients at high risk for conventional surgery. Aortic valve insufficiency was mild, with no malperfusion syndrome. A Teflon plaque or Dacron vascular prosthesis was passed around the aorta and tightened from the coronary ostia to the innominate artery. No severe neurologic complications or deaths occurred in the postoperative period. Computed tomography and magnetic resonance imaging imaging during follow-up showed aortic diameters had stabilized in all patients.
