Postoperative growth of the left subclavian artery in a case after a modified Blalock-Park procedure
Insights
The modified Blalock-Park procedure offers a viable treatment for infants with severe aortic coarctation and hypoplastic aortic isthmus. Long-term follow-up confirmed successful aortic arch development and no pressure gradients, indicating a recommendable surgical option.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Defects
- Aortic Coarctation Treatment
Background:
- Coarctation of the aorta in infancy necessitates surgical intervention but often results in high mortality and reoccurrence.
- Existing surgical methods for aortic coarctation carry significant risks and complications.
Abstract:
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.
