Hypothermic circulatory arrest through a left thoracotomy in a 12-year-old child with aortic coarctation.

Surgical correction of adult complex aortic coarctation using hypothermic circulatory arrest often requires central cannulation to secure cerebral perfusion. It is not easy to place the cannula in the ascending aorta, however, especially in children undergoing surgery through a left thoracotomy. In a 12-year-old male with hypoplastic distal aortic arch, we placed an arterial cannula in the ascending aorta using the Seldinger puncture technique through the stenotic segment of the distal aortic arch. Replacement of the stenotic segment with a 20 mm-size Dacron graft was then routine. The ascending aorta was exposed only for the proximal anastomosis. The left subclavian artery was also reconstructed. This central cannulation technique is simple and is useful in repairing complex aortic coarctation.
