| English abstract | OBJECTIVE: To evaluate the immediate postoperative results of off-pump myocardium revascularization surgery by analyzing complications and mortality. METHOD: A total of 1440 patients were submitted to off-pump myocardium revascularization. The surgical technique is consisted in proximal occlusion of the approached artery, the application of the LIMA graft in the posterior pericardial deflection and stabilization of the target artery with a suction stabilizer. The distal anastomoses were performed first. RESULTS: Among the patients evaluated, 924 were male and 516 were female,with a mean age of 63.12 ± 8.76 years. The ejection fraction was normal in 749 patients, 740 (51.4%) patients had suffered previous myocardial infarction and 687 (47.6%) patients were in functional class III or IV. The mean EuroSCORE was 4.93 ± 3.32. The mean number of dial anastomoses was 3.12 ± 1.23 per patient. A total of 1173 (81.5%) patients remained less than 12 hours on mechanical ventilation and among them, 888 (61.7%) remained for less than six hours. The stay in the ICU was of one night for 330 (22.8%) patients, for two nights for 930 (64.6%) patients and 182 (12.4%) patients remained three or more nights. In regards to complications, three (0.2%) patients presented with renal insufficiency, six (0.4%) patients suffered stroke, 19 (1.3%) patients were reoperated for bleeding, 19 (1.3%) patients had mediastinitis, 18 (1.25%) patients suffered severe myocardial infarction and 212 (14.7%) presented atrial fibrillation. There were 50 (3.5%) deaths, 29 (2.5%) of them being among the 1148 operated electively, nine (4.7%) among 190 patients submitted to coronary re-operation and 12 (11.7%) among 102 patients undergoing emergency operations. CONCLUSION: With the evolution of biomedical technological, all the vessels of the heart are now approached. These data suggest that the operation for myocardial revascularization is safe and efficient. It can be app |

MÉTODO: Foram submetidos à operação para revascularização do miocárdio sem circulação extracorpórea 1440 pacientes. A técnica operatória consistiu em oclusão proximal da artéria abordada, aplicação do ponto de LIMA na deflexão pericárdica posterior e estabilização da artéria alvo com estabilizador de sucção. As anastomoses distais foram feitas inicialmente. RESULTADOS: Entre os pacientes avaliados, 924 eram ao sexo masculino, com idade média de 63,12±8,76 anos. A fração de ejeção era normal em 749 pacientes. Setecentos e quarenta (51,4%) pacientes tinham antecedente de infarto do miocárdio. Seiscentos e oitenta e sete (47,6%) pacientes encontravam-se em classe funcional III ou IV. O EuroSCORE médio foi de 4,93±3,32. A média de anastomoses distais foi de 3,12±1,23 por paciente. Mil cento e setenta e três (81,5%) pacientes permaneceram menos de 12 horas em ventilação mecânica, sendo que destes, 888 (61,7%) permaneceram menos de 6 horas entubados. A permanência em UTI foi de uma noite em 330 (22,8%) pacientes e de duas noites em 930 (64,6%). Cento e oitenta e dois (12,4%) pacientes permaneceram três ou mais noites na UTI. Quanto às complicações, três (0,2%) pacientes apresentaram insuficiência renal, seis (0,4%) tiveram acidente vascular cerebral, 19 (1,3%) foram reoperados por sangramento, 19 (1,3%) tiveram mediastinite, 18 (1,25%) infarto agu |
