Brasil. 53 pacientes fueron sometidos a RM con Circulación Extracorpórea (RMCEC), y 15 a RM sin Circulación Extracorpórea (RMSCEC). Sus datos demográficos, factores de riesgo preoperatorios, complicaciones y evolución postoperatoria fueron evaluados.
Resultados: El tiempo quirúrgico fue menor en el grupo de RM-SCEC, requiriendo menos unidades de paquetes globulares y de plasma fresco congelado que el grupo de
RM-CEC. Las complicaciones postoperatorias, estancia hospitalaria, y mortalidad, fueron a su vez menores en el grupo de
RM-SCEC.
Conclusiones: En el grupo de RM-SCEC se observó menor tiempo de estancia hospitalaria, menor morbilidad postoperatoria y no hubo mortalidad.
En el grupo de RM-CEC, el tiempo de estancia hospitalaria, la morbilidad y mortalidad postoperatorias fueron mayores, observándose sin embargo, la presencia de un mayor número de factores de riesgo preoperatorios en este grupo.
Palabras Claves: Cirugía de Revascularización Miocárdica, Circulación Extracorpórea, Octogenarios.
SUMMARY
OFF PUMP AND ON PUMP CORONARY ARTERY BYPASS SURGERY IN OCTOGENARIANS.
Objective: Determine the potential benefits of Off pump coronary artery bypass surgery in octogenarians.
Methodology: Records of 68 consecutive octogenarian patients who underwent coronary artery bypass grafting (CABG) surgery (February 1998 -September 2000), at the Heart Institute (InCor), University of SAo Paulo Medical School, Brazil, were retrospectively reviewed. 53 patients underwent On - pump coronary artery bypass (ONCAB) surgery and 15 underwent Off-pump coronary artery bypass (OPCAB) surgery. Their demographic data, preoperative risk factors, postoperative complications and outcomes, were evaluated.
Results: Operative time was lower in the OPCAB group, requiring less units of packed red blood cells and fresh frozen plasma than the ONCAB group. Postoperative morbidity, mean hospital stay and mortality were also lower in the OPCAB group.
Conclusions: We found less in-hospital stay, less postoperative morbidity, and no mortality in the OPCAB group.
In-hospital stay, postoperative morbidity and mortality, were greater in the ONCAB group, nevertheless there were more preoperative risk factors in this group.
Key Words: Coronary Artery Bypass Grafting Surgery, On - pump, Off - pump, Octogenarians.
