Aortic Aneurysm and Aneurysmal Endarteritis After Resection for Coarctation

Three cases in which aneurysm of the aorta developed at or near the site of anastomosis after resection for coarctation have been reported, but there is no record of a case such as this one, in which the condition was complicated by intra-aneurysmal endarteritis. A 6-year-old boy had undergone surgical correction of coarctation of the aorta on April 21, 1953, 10 months before we saw him. The aorta had been clamped near the origin of the intercostal artery that was uppermost in the operative field, and near the base of the subclavian artery. Then a segment of the aorta 1 cm. in length had been resected. The incision across the proximal part of the aorta (the part between the aneurysm and the heart) was described as oblique, so that the lumen of each cut end of the aorta had been about 2 cm. in diameter. End-to-end anastomosis had been made,
