Surgical management of severe aortic coarctation and interrupted aortic arch in neonates.
Forty-four infants, 2 to 90 days of age, with severe obstructive lesions of the aortic arch, underwent emergency surgical correction between Jan. 1, 1966, and April 1, 1975. The typical clinical presentation was severe congestive heart failure and acidemia. Resection of an aortic coarctation with end-to-end anastomosis was performed in 31 patients. Eight (26 per cent) died after the operation. Since 1969, the mortality rate has been reduced to 14 per cent (3 of 22 patients) even though the incidence of major associated cardiac lesions has remained essentially constant (56 per cent from 1966 through 1969, 64 per cent from 1970 through March, 1975). This suggests that the higher survival rate has resulted from improved surgical techniques and postoperative care. The mortality rate in the infants operated upon during the second and third months of life was twice as high as that in those operated upon before the age of 1 month. Eight patients with Type A interrupted aortic arch were operated upon and 5 survived. Five patients with Type B aortic arch were operated upon and 3 survived.
