Which of the following would be an acceptable method of repair for a neonate with symptomatic isolated coarctation of the aorta?

A. Resection with end-to-end anastomosis

C. Subclavian flap aortoplasty.

DISCUSSION: The most commonly used methods for coarctation repair are resection with anastomosis and subclavian flap aortoplasty. Both have been shown to provide adequate relief of the obstruction with acceptable rates of restenosis. The choice of repair depends on the patient's anatomy and the surgeon's experience. Patch aortoplasty was used frequently in the past; however, because of concern over restenosis and aneurysm formation it is no longer commonly performed. Prosthetic tube graft repair is avoided except in some complex cases and some cases of recoarctation.
