Abstract
The operative morbidity and mortality of patients with Stanford type A acute aortic dissection undergoing urgent operation using retrograde cadioplegia for myocardial protection were evaluated to assess the efficacy of such surgery. A total of 18 patients (12 men and six women. 19–71 years of age) were operated on 9–137 h after onset of dissection using cardiopulmonary bypass with deep hypothermia and retrograde cardioplegia. Graft replacement was performed in ten patients, primary anastomosis in three, and Cabrol and Bentall operations in five. All patients were weaned from cardiopulmonary bypass, but four died in hospital (mortality rate 22%). Thirteen patients were in good health at follow-up ranging from 3 to 98 months, and the remaining patient died from rectal cancer 5 months after surgery. It is concluded that urgent operation of patients with Stanford type A acute aortic dissection can be performed with reasonable operative and excellent follow-up results. Retrograde cardioplegia is an easy and reliable method of myocardial protection to repair the fragile aortic wall.
