Whether the site of operation for coarctation of aorta has grown or not after resection and end-to-end anastomosis is an important factor to affect long term results, as an operation takes place in infancy in most cases. However, because aortography is necessary to know the growth exactly, clinical investigations are scarce. Excluding one case of recoarctation and the other with no sufficient data at the operation, we were able to confirm growth at the anastomotic site in 7 cases. Therefore, we believe that resection and end-to-end anastomosis is a useful technique as a surgical treatment of coarctation of aorta without sacrificing the subclavian artery and using prosthesis.
