title: [Long-term results of the surgical treatment of acute type A thoracic aortic dissection].
abstract: Out of a population of 110 patients operated as an emergency for acute Stanford type A dissection of the thoracic aorta between 1985 and 1994, there were 84 survivors. Seventy-nine were assessed after a mean follow-up period of 47.3 months. The corrected 1 year, 5 year and 10 year survival rates were 69 +/- 5.1%, 53.1 +/- 6% and 42.1 +/- 7.1% respectively. There were 19 deaths during the study period: in two thirds of cases death was due to cardiovascular complications related to the aortic pathology or hypertension. There were 13 reoperations in 12 patients for complications on the initial site of repair or for progression of the pathological process. The average time to reoperation was 21.5 months with an operative mortality of 3 patients (25%). Predictive factors of reoperation were young age (52 +/- 4.4 years vs 60.1 +/- 1.4 years; p = 0.037), the persistence of a patent false lumen (p = 0.033) and the initial surgical techniques as the incidence of reoperation seemed to be higher after treatment with biological glue alone or resuspension of the aortic valve compared with replacement of the ascending aorta or Bentall's procedure (p = 0.08). The incidence of reoperation also varies with time as it was 1.8 +/- 0.7% at 1 year, 18.5 +/- 6.5% at 5 years and 26% +/- 7.8 at 10 years. In spite of improvements in surgical technique and postoperative care, acute type A dissection of the aorta carries a poor prognosis in both the short and the long-term with a notable number of cardiac or other complications related to repair of the initial aorta. Analysis of these and other reported results suggest that initial surgery should be as complete as possible with extension to the aortic arch when involved: this more aggressive attitude should improve the long-term results by reducing the risk of reoperation responsible for a high mortality rate.
