ABSTRACT

Objective:

To summarize the results of surgical treatment for complete atrioventricular septal defect(CAVSD) in early and middle stages.

Methods:

147 children with CAVSD in Guangzhou Women and Children’s Medical Center from January 2010 to December 2019 were selected, Males 85, females 62, median age of surgery 5 months(1 months-10 years old), median body mass 5.5 kg(2.4-20.9 kg). Complete atrioventricular septal defect was diagnosed by ultrasonic cardiogram before surgery. All the children underwent atrial ventricular valve formation and underwent simultaneous repair.Outpatient follow-up was planned.Ultrasonic cardiogram and electrocardiogram were performed. SPSS 22 statistical software was used for data analysis.

Results:

All 147 CAVSD patients underwent one-time surgical correction.Early postoperative death occurred in 7 cases(4.76%). The causes of death were 3 cases of pulmonary hypertension crisis, 3 cases of severe mitral insufficiency(MI), 1 case of postoperative malignant arrhythmia, and the rest of the children were cured and discharged. Permanent pacemaker was installed in 3 patients due to atrioventricular block(AVB). The follow-up time was 1-10 years old, and 2 patients died in late stage 1 patient did not seek medical treatment in time due to infection, and 1 patient had unknown cause. Five patients underwent secondary surgery 4 due to severe mitral/tricuspid insufficiency(MI/TI) and 1 due to delayed AVB. The mid-term follow-up showed 9 cases of severe MI and 4 cases of severe TI. Compared with children with surgical age<3 months and ≥3 months, there were statistically significant differences in postoperative ventilator-assisted ventilation time, severe MI before postoperative discharge and total mortality between the two groups( P<0.05). Mid-term follow-up results showed no difference between the two groups. There were statistically significant differences in surgical age, postoperative CICU stay time and total hospital stay between the children with trisomy 21-syndrome and those without trisomy 21-syndrome( P<0.05), and there was no difference between the two groups in mid-term follow-up results. Residual shunt of 1-3 mm VSD was found in 29 cases, 26 cases were closed during follow-up, and 3 cases had smaller residual shunt.

Conclusion:

Modified single patch technique treatment of CAVSD has good effect, low mortality and low re-operation rate. But age <3 months group, infant mortality was significantly increased, the duration of postoperative mechanical assisted ventilation was prolonged, and the proportion of early postoperative severe MI was high.Severe MI and TI is easy to occur after CAVSD, which requires long-term follow-up and timely treatment. The children with trisomy 21-syndrome were similar to those with normal chromosome except for longer stay in ICU and total hospital stay.
