대동맥 교약증의 수술요법 -12년간의 수술경험-

Surgical Management of Coarctation of the Aorta: 12 Years of Experience

During the twelve-year period from March 1973 through July 1984, 23 consecutive operations for coarctation of the aorta were performed at Seoul National University Hospital. The patients included 19 male and 4 female in the range of 4 months and 16 years old. Associated cardiac anomalies were present in 19 patients [70%] and they were VSD+PDA [9 patients], VSD[2], PDA[1], VSD+ASD+PDA[1], VSD+MS+AS+PDA[1], D-TGA+VSD+PDA[1], P-ECD[1], MS[1], Al[1], and DORV+PDA[1]. The preoperative main symptoms included congestive heat failure, hypertension, subacute bacterial endocarditis and nonspecific symptoms. Congestive heart failure was the most common symptom in the group younger than 2 years and hypertension in the adult group. Operative techniques for coarctation of the aorta were resection and end to end anastomosis in 10 patients, prosthetic patch aortoplasty in 8, subclavian flap aortoplasty in 4, and LSCA-aortic anastomosis in 1. There were 4 operative deaths among the nine patients less than 2 years old[44.4% mortality]: all of these patients had associated cardiac anomalies. And only one operative death occurred in patients older then 2 years old[7.1% mortality]. No hospital death occurred in patients with isolated coarctation of the aorta. Operation of the coarctation was performed primarily in 6 patients associated with ventricular septal defect and subsequently underwent successful VSD closure except one operative death.
