Surgical repair of coarctation of the aorta in infants under one year of age. Long-term results in 146 patients comparing subclavian flap angioplasty and modified end-to-end anastomosis.
Between July 1976 and February 1991, 146 consecutive infants underwent surgical repair of coarctation of the aorta. Age at operation varied from 2 days to 11 months (median 1 month). Ninety-two (63%) were less than 2 months. Isolated coarctation was present in 65 patients (group 1), associated ventricular septal defect in 49 patients (group 2) and complex anomalies in 32 patients (group 3). The majority (65%) were in a critical condition and 45 patients (31%) were artificially ventilated. Subclavian flap angioplasty was performed in 39 patients and resection and end to end anastomosis in 107 patients. Neither hospital mortality was significantly different between subclavian flap angioplasty (15%) and end-to-end anastomosis (18%) nor was the postoperative hypertension. Actuarial survival at 10 years were 100% for group 1, 94% for group 2, and 62% for group 3. Seventeen patients had recurrent coarctation. No significant difference was found in terms of types of repair or age at operation. As no major advantage in terms of mortality and morbidity to either technique was found, we recommend resection and end-to-end anastomosis. This technique not only relieves the obstruction whatever the level is but also eliminates the ductal tissue, preserves the subclavian artery and avoids the use of prosthetic material.
