1972年1月至1983年6月,作者为57例2岁以下的大室缺患儿做了修复手术。年龄1～24个月,平均12.2±1.8月;体重2.5～12.2 kg,平均6.6±0.9 kg;男性31例,女性26例。患儿均有大室缺的典型临床表现,因充血性心力衰竭而治疗,接受地高辛。大多发育迟缓,喂养困难。手术适应证包括:充血性心力衰竭或影响生长发育51例,肺血管阻力增加3例,后天性右室流出道梗阻2例,2岁前择期手术者1例。心电图显示双室肥厚,胸片可见心脏增大,肺血管影增多。所有患儿均进行了术前导管检查,血管造影电影。肺循环血流量与体循环血流量之比为0.5～8.0(平均3.5±0.5),
From January 1972 to June 1983, the author underwent repair surgery for 57 under-2-year-old children with large or large children. Aged 1-24 months, an average of 12.2 ± 1.8 months; body weight of 2.5 ~ 12.2 kg, an average of 6.6 ± 0.9 kg; 31 males and 26 females. Children have a large clinical manifestations of the lack of room, due to congestive heart failure treatment, to receive digoxin. Mostly stunted, feeding difficulties. Surgery indications include: congestive heart failure or growth and development in 51 cases, pulmonary vascular resistance increased in 3 cases, acquired right ventricular outflow tract obstruction in 2 cases, 2 years before elective surgery in 1 case. ECG showed double room hypertrophy, chest X-ray shows increased heart, increased pulmonary vascular shadow. All children underwent preoperative catheterization and angiography. The ratio of pulmonary blood flow to systemic blood flow was 0.5 to 8.0 (mean 3.5 ± 0.5)
