ABSTRACT
Objective To sum up the therapeutic results of 125 cases of tetralogy of Fallot(TOF),and ex- plore the optimal time and risk factors of opration,as well as perioperative management.Methods One hundred and thirth-one consecutive cases of TOF underwent corrective surgery.There were simple stenosis of infundibular portion in right ventricular outflow tract in 37 cases,stenosis of infundibulum and pulmonary valve in 14 cases,main pul- monary trunk and left/right pulmonary arteries stenosis in 74 cases,and pulmonary atresia in 5 cases.Autologousper- icardial conduit,or with waived were used for right ventricular outflow tract and right ventriculo-pulmonary artery connection.Other anomalies were corrected.Results The surgicalmortality was 4.0 %.The cause of death were se- rious low cardiac output syndrome(3 patients),respiratory function failure(1 patient),pericadial infection(1 pa- tient).Conclusion It is necessary to profonn corrective opration on younger TOF patients.Effetive prophylaxis and control of low cardiac output syndrome and pulmonary complication is a useful strategy.
