Abstract:
Objective The study aimed to evaluate the short and middle term results in the patients with tetralogy of Fallot(TOF) after one-stage repair and staged repair.Methods A total of 459 TOF younger children less than five-year-old between January 2009 and December 2013 had received surgical repair,including 416 patients by one-stage repair(group Ⅰ)and 43 patients by staged repair(group Ⅱ).Among them,245 were male and 214 were female.The average repair surgical age was 27.8 ranged from 4 to 60 months,average palliation age was 15.4 ranged from 3 to 40 months.23 perioperative and follow-up parameters were assessed including sex,age,weight,preoperative clinic symptom,ratio of McGoon,pulmonary artery index,Z score of pulmonary annulus,cardiopulmonary bypass time,aortic cross-clamping time,type of VSD repair,type of RVOT procedure,Peak RV/LV pressure radio,RV-PA pressure grade,mortality,severely low cardiac output syndrome,hypoxemia,extubation time,ICU time,fellow-up time,left ventricular eject faction,RV index of myocardial performance (MPI),tricuspid annular plane systolic excursion(TAPSE) and pulmonary regurgitation.Results Compared with group Ⅰ,age and weight were significantly lower in patients in group Ⅱ[(19.1 ± 16.4) months vs.(21.1 ± 11.2) months,P ＜ 0.05) and(19.1 ±16.4) kgvs.(21.1 ±11.2) kg,P ＜0.01].The Z score of pulmonary annulus of patients in group Ⅱ were significantly less than those in group Ⅰ (-3.69 ± 2.36 vs.-2.50 ± 1.95,P ＜ 0.01).The ratio of repairing VSD by RV incision and using TAP in patient of group Ⅱ were significantly more than those in group(27/43 vs.71/413,P ＜0.01),(41/43 vs.221/413,P ＜0.01).There was no difference of mortality,complication,extubation time and ICU time bewteen two groups.All patients followed up 12-52 months,there was no difference of LVEF,MPI and TAPSE between two groups.However,the severity of pulmonary regurgitation in patients of group Ⅱ was significant more than those of group Ⅰ (47.6％ vs.32.1％,P ＜ 0.01).Conclusion The early and mid-term results in the the young children patients with TOF after one-stage repair or staged repair were good.Although the prior palliative shunt could promote the development of the hypoplasia pulmonary arteries in the young children patient,it may related to the technique of repairing operations and the postoperative pulmonary regurgitation.
