  • Application of Modified Lateral Tunnel Fontan Procedure on Complex Congenital Heart Disease in Children

    Objective To summarize the treatment experiences of Modified lateral tunnel(LT) Fontan operation on complex congenital heart disease in children and investigate the advantages of this operation. Methods From March 1999 to August 2008, 86 patients with cynosis complex congenital heart disease underwent LT Fontan operation in our hospital. There were 47 male and 39 female aged 1.9-11.5 years with a mean age of 4.7 years and weighed 8.6-52.0 kg with a mean weight of 17.0 kg. There were 33 cases with asplenia syndrome, 17 cases with polysplenia syndrome, 11 cases with tricuspid atresia(TA), 11 cases with double outlet right ventricle(DORV) of atrioventricular discordance, 8 cases with complete transposition of great arteries(D-TGA) complicated with pulmonary stenosis, 5 cases with corrected transposition of great arteries(cTGA) and 1 case with Ebstein’s anomaly. Unilateral superior bidirectional superior cavopulmonary anastomosis(BSCPA), bilateral bidirectional superior cavopulmonary anastomosis and hemiFontan opertion were done before operatipon. The time between two operations was 0.7-7.8 years(3.6±2.9 years). LT Fontan operation(LT-group, 47cases) and Modified LT Fontan operation(M-LT group, 39cases) were used in operation to drain blood from inferior vena cava to right pulmonary artery. Partly completed secondstage M-LT Fontan operation. Results There were 7 deaths in two groups(9%), 5 in LT group and 2 in M-LT group. There was no statistical significance(χ2=0.865,P=0.448). In stagemodified LT Fontan operation, there were significantly more cases who had BSCPA operation preoperatively in MLT group than that in LT group. Twentytwo cases had low cardiac output syndrome after operation, 13 cases underwent peritoneal dialysis because of renal dysfunction, and theirurine volume recovered after 2-5 days’ dialysis. There were significantly more cases who had arrhythmia in LT group than that in M-LT group(χ2=8.763,P=0.003). The time of chest drainage was longer in LT group than that in M-LT group(t=2.970,P=0.003). The follow-up time was 3 months8 years. No death was found. In M-LT group 33(85%) cases were followed up and in LT group 39(83%)cases were followed up. No severe complication was found. Patients’ activity ability improved significantly. Conclusion The M-LT Fontan operation is an advanced operation to improve the success rate of operation and reduce postoperative complications.
