[Experience of modified Bentall's procedure for annulo-aortic ectasia].

To reduce the incidence of false aneurysm formation at the suture lines, a known complication with the inclusion technique such as Bentall's procedure or Cabrol's procedure, modified Bentall's procedure (Carrel patch technique), which is identical to Inberg's procedure, has been selected as treatment for annulo-aortic ectasia since 1991. This operation was carried out in 6 consecutive patients with annulo-aortic ectasia from July 1991 to August 1992. The aortic valve and the aneurysm were resected, the coronary ostia were dissected free, mobilized, and then implanted to the composite graft. It was necessary for one patient to undergo coronary artery bypass grafting for myocardial ischemia due to injury of the right coronary ostium. Thereafter, the button of coronary ostium was cut into a big size and then trimmed just before the implantation to the composite graft in order to prevent injury of the button of the coronary ostium. There was no hospital mortality. No pseudo-aneurysm at the coronary ostia or the distal aortic anastomosis was observed at control aortography carried out 1 month after surgery. One patient died 1 year after the first operation because of low cardiac output after the re-operation for pseudo-aneurysm at the proximal aortic anastomosis and infection of the composite graft. All the other patients have been symptom free during follow-up. The use of gelatin impregnated dacron graft and the reinforcement of the suture lines by Teflon felt strips minimized bleeding. One patient underwent this operation without blood transfusion.(ABSTRACT TRUNCATED AT 250 WORDS)
