총폐정맥 환류이상증의 외과적 치험 4예

Total anomalous pulmonary venous return is a cardiac malformation in which there is no direct connection between any pulmonary vein and the left atrium but, rather all the pulmonary veins connect to the right atrium or one of its tributaries. TAPVC is a relatively uncommon anomaly, accounting for only about 1.5-3% of cases of congenital heart disease. Recently improvement in intraoperative techniques did eventually bring substantial improvements in the results in infants. 4 cases of TAPVC was successfully treated with one-stage operation, in the Dept. of Thoracic and Cardiovascular Surgery, National Medical Center in which 2 cases are supracardiac types and the other 2 cases are cardiac types. Sex ratio was 1:1, and the range of age was 2 years-18 years. The common pulmonary venous sinus was connected to the left vertical vein and innominate vein: in 2 supracardiac types and coronary sinus in 2 cardiac types. All cases are operated with standard cardiopulmonary bypass, and the hospital mortality was 0%.
