Surgical Repair for Aortic Coarctation in Children Aged Less than One Year / 日本心臓血管外科学会雑誌

ABSTRACT

The operative results in case of aortic coarctation (CoA) were studied. Between June 1980 and June 1995, 37 children with CoA underwent surgical intervention during their first year of life in our institute. The aortic lesion was repaired by the subclavian flap (SCF) method in 27, direct anastomosis (DA) method in 7, grafting or other methods in 3 children, respectively. The mean follow up period was 7.4±5.3 years (6 months-13 years). Rate of re-stenosis of the aorta was 10% (2 in 20 children) after SCF method, 0% (0 in 7 children) after DA method. The stenotic lesion was successfully dilated by the percutaneous balloon reconstruction in one child. Perioperative mortality was 25% (1/4) in one-stage repair, while one-stage repair was successfully performed in the last three cases and 16.6% (3/18) in two-stage repair for CoA associated with ventricular septal defect (VSD). The mortality was 60% (6/10) of CoA associated with other complex anomalies. In conclusion, one-stage repair seems to be recommendable for the operation of CoA with VSD, and two-stage repair seems to be safe for CoA with complex anomalies.
