RESUMO
Objective To summarize the experience of perioperative management of coronary artery bypass graft(CABG) in high-risk patients with coronary heart disease.Methods The clinical data of 164 patients underwent CABG from March 2004 to November 2005 were analyzed.Of 164 patients,151(92.05%) cases had severe coronary heart disease.Results Totally 144 artery-vessels and 353 venous-vessels were transplanted to patients.Combined operative procedures included 11 cases of ventricular aneurysm resect,5 cases of valve replacement,5 cases of valve repair,and 1 case of surgical repair of perforation of ventricular septum.Post-operative complications included 2 cases of low cardiac output,1 case of respiratory failure,1 case of renal failure,and 1 case of cerbral infarction.Two patients died and the operative mortality was 1.22%.Conclusion CABG procedure is safe in the treatment of high-risk patients with coronary heart disease.Proper preoperative and perioperative treatment can improve the curative effects significantly.
