Key result
A modified Blalock-Park procedure using side-to-side anastomosis in a 12-month-old infant resulted in normal growth of the left subclavian artery with no pressure gradient after 12 years.
Why the study?
Does a modified Blalock-Park procedure prevent recoarctation and allow normal growth of the reconstructed aortic arch in infants with severely hypoplastic aortic isthmus?
Case Report (n=1)
No
Does a modified Blalock-Park procedure prevent recoarctation and allow normal growth of the reconstructed aortic arch in infants with severely hypoplastic aortic isthmus?
A modified Blalock-Park procedure using side-to-side anastomosis and interrupted sutures allows for normal growth of the reconstructed aortic arch without recoarctation in infants with hypoplastic aortic isthmus.
Answers are grounded in this paper and cite their sources.
Single case shows sustained arch growth without gradient; leaves open whether this prevents recoarctation in hypoplastic isthmus.

Med., 1986, 150 (1), 25-30-Various kinds of operations for coarcation of the aorta in infancy are life saving, but they still carry a high operative mortality rate and are followed frequently by residual or recurrent coarctation. Fifteen years ago we performed a modified Blalock-Park procedure on a 12 month old male infant with preductal coarctation, a large VSD and PDA. Recently a follow-up study was performed on this patient. Aortography revealed a normally developed aortic arch without any sign of stenosis. The intraaortic pressure tracings revealed no pressure gradient through the aortic arch and thoracic aorta. These findings suggest that this procedure is recommendable for the treatment of infants with severely hypoplastic aortic isthmus.

Ishizawa et al. (1986) conducted a case report in Preductal coarctation of the aorta, large VSD, and PDA (n=1). Modified Blalock-Park procedure was evaluated on Postoperative growth of the left subclavian artery and pressure gradient. A modified Blalock-Park procedure using side-to-side anastomosis in a 12-month-old infant resulted in normal growth of the left subclavian artery with no pressure gradient after 12 years.
