[Extended aortic arch anastomosis for coarctation of the aorta and interruption of the aortic arch in early infancy].
We performed extended aortic arch anastomosis, which was so called EAA procedure, for Coarctation of the Aorta (CoA) with hypoplastic aortic arch (HAA) and interruption of the aortic arch (IAA) in 17 infants under three months of age. The proximal anastomosis site was extended into ascending aorta in order that we could make non-obstructive pathway of systemic flow. During anastomosis, we employed mild systemic hypothermia and topical cooling of head and lumber lesion. Satisfactory anastomoses were performed without any neurological and renal complications except one case. Postoperative Doppler echographic evaluation revealed that the mean peak flow velocities at anastomotic site were under 2.0 m/sec at 1 and 2 years after surgery. We concluded that EAA procedure was useful for CoA with HAA and IAA in early infancy.
