    Abstract:
    Single stage repair of syndromes of coarctation and interruption of the aortic arch is a routine procedure in many surgical centres with good immediate results. The classical technique of aortic repair is based on the principles of Crafoord's extended resection anastomosis. Recoarctation is not an unusual long-term complication. A technique of enlarging angioplasty of the aorta using a patch of pulmonary artery has been developed and used in 22 neonates with obstruction of the aortic arch associated with ventricular septal defect with an average age and body weight of 15 days and 2.9 Kg respectively. The ventricular septal defect was closed surgically during the same procedure. Total circulatory arrest was not used in these children and all had aortic repairs with selective cerebral perfusion with moderate hypothermia (28-30 degrees C). This technique was used without any procedure-related early morbidity. No early or late deaths were observed in this series. Two patients were reoperated during the first year after the initial procedure: one for residual ventricular septal defect and the other for supraventricular pulmonary stenosis. Two patients, one of whom was reoperated, developed supraventricular pulmonary stenosis with a gradient of over 60 mmHg. These stenoses were observed in the first cases operated and were essentially due to the technique of pulmonary artery reconstruction. Over a median follow-up period of 10 months, no recoarctations were observed: the Doppler ultrasound study showed an isolated mean systolic gradient of 6 +/- 12 mmHg. The authors conclude that angioplasty of the aortic arch with an enlarging patch of pulmonary artery autograft during single stage surgery of syndromes of coarctation and interruption of the aortic arch provides a harmonious and durable repair of the aortic arch.
