Abstract

Objective: A retrospective study was perfomed in a series of consecutive patients who underwent a Bentall and De Bono procedure. Methods: Data were removed of medical records and follow-up data were obtained from clinical records and direct contact with patients. A total of 39 patients were studied between January 1996 and December 2005. Results: The median age was 47 years (range 14-70). There were 33 males and six females. Eleven patients (25.5%) presented Marfan syndrome and one (2.5%) Turner syndrome. Nineteen patients (48.5%) had hypertension, eight (20.5%) had history of smoking, six (15.5%) had history of alcoholism, eight (20.5%) had dyslipidemia, two (5.0%) had diabetes and one (2.56%)had myocardial infarct previously. 28 patients (72.0%) were in II-III NYHA class in the moment of the surgery. Annulo-aortic ecatsia was present in 14 patients (35.90%) and aortic aneuryms in 16 (41.0%). The median time in intensive care unit was 8,79 days with range 2-23 days. Four patients underwent an emergency opertation (10.0%) and 35 (90.0 %) elective. The overall hospital mortality was 5.0 % (2/39). The event-free survival is 94.87% at 1 year and 84.61% at in 5 and 10. The median time of follow-up was 46.5 months (range 14-120 months). Conclusion: The Bentall and De Bono technique obtained excellent results in the short-term and long-term, which support the continued use of the compositive graft technique as the preferred method of treatament for patients with aortic root disease. Our findings confirm the current literature data.
