RESUMEN
OBJETIVO: Avaliar a perviedade dos enxertos no intraoperatório e identificar enxertos com risco de oclusão precoce. MÉTODOS: Cinquenta e quatro pacientes foram submetidos à revascularização do miocárdio e foi utilizado o fluxômetro (Medtronic Medi-Stim) que utiliza o método de tempo de trânsito (TTFM) para avaliação do fluxo nos enxertos. Três pacientes tinham lesão de tronco de artéria coronária esquerda e 48 apresentavam função ventricular normal ou pouco comprometida. RESULTADOS: A mortalidade hospitalar foi de dois (3,7%) pacientes, um por trombose mesentérica e outro por choque cardiogênico. Dezessete (31,4%) pacientes foram operados sem circulação extracorpórea (CEC). O fluxo no enxerto arterial variou de 8 a 106 ml/min, com média de 31,14 ml/min, e nos enxertos venosos de 9 a 149 ml/min, com média de 50,42 ml/min. CONCLUSÃO: O fluxômetro representa maior segurança para o cirurgião e para o paciente. Até mesmo sob o aspecto legal essa documentação dos enxertos pérvios evitará questionamentos futuros.
OBJECTIVE: To evaluate intraoperative graft patency and identify grafts under risk of early occlusion. METHODS: Fifty four patients were submitted to coronary artery bypass surgery and the graft flow was assessed by the Flowmeter (Medtronic Medistim), which utilizes the TTFM method. Three patients had left main disease and 48 had normal or mildly reduced left ventricular function. RESULTS: In hospital mortality was 3.7% (two patients), one for mesenteric thrombosis and one due to cardiogenic chock. Seventeen patients (34%) were submitted to off pump CABG. Arterial Graft flow measures ranged from 8 to 106 ml/min (average 31.14 ml/min), and venous grafts flow ranged from 9 to 149 ml/min (average 50.42 ml/min). CONCLUSION: Flowmeter use represents higher safety both for patients and surgeons. Even under legal aspects, the documentation provided by the device can avoid future questionings.

OBJECTIVE: A retrospective study was performed 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 (25.5%) patients presented Marfan syndrome and one (2.5%) Turner syndrome. Nineteen (48.5%) patients 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. Twenty-eight (72%) patients were in II-III NYHA class in the moment of the surgery. Annulo-aortic ecstasy was present in 14 (35.9%) patients and aortic aneurysms in 16 (41%). The median time in intensive care unit was 8.79 days with range 2-23 days. Four (10.0%) patients underwent an emergency operation and 35 (90%) elective. The overall hospital mortality was 5% (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 treatment for patients with aortic root disease. Our findings confirm the current literature data.

OBJETIVO: Um estudo retrospectivo foi desenhado tendo como fator de inclusão a cirurgia de Bentall e De Bono. MÉTODOS: Dados foram retirados de prontuários médicos e informações de seguimento a longo prazo obtidas por meio de retornos ambulatoriais e contatos diretos com o paciente. Trinta e nove pacientes foram acompanhados no período de janeiro de 1996 a dezembro de 2005. RESULTADOS: A mediana de idade foi 47 anos, sendo 85 por cento dos pacientes do sexo masculino. Onze (25,5 por cento) pacientes apresentavam síndrome de Marfan e um (2,5 por cento) síndrome de Turner. Entre os fatores de risco, listaram-se: hipertensão em 19 (48,5 por cento) pacientes, tabagismo em oito (20,5 por cento), etilismo em seis (15,5 por cento), dislipidemia em oito (20,5 por cento), diabetes melito em dois (5 por cento) e presença de IAM prévio em um (2,5 por cento). Vinte e oito (72 por cento) pacientes estavam em classe II-III NYHA ao momento da operação. Ectasia ânulo-aórtica era diagnóstico em 14 (36 por cento) pacientes e aneurisma da aorta em 16 (41 por cento). O tempo médio de permanência na UTI foi 8,8 dias, com intervalo de 2-23 dias. A taxa de sobrevida em 30 dias (intra-hospitalar) foi de 94,87 por cento (2/39). Em um ano, 37 (94,87 por cento) pacientes estavam vivos, e em 5 e 10 anos, 33 (84,61 por cento). O tempo de acompanhamento médio foi de 46,5 meses, com intervalo de 14-120 meses. CONCLUSÃO: A técnica descrita por Bentall e De Bono obteve excelentes resultados a curto e longo prazo, sendo eficaz e segura no tratamento de doenças da valva aórtica e aorta ascendente em nosso serviço. Nossos resultados são condizentes com dados atuais da literatura.
