Juxtarenal Aortic Aneurysm after Successful Repair of Ruptured Infrarenal Aneurysm

RESUMO

Eight months after successful repair of a ruptured infrarenal aneurysm, a 50-year-old hypertensive male patient was found to have a 2nd aneurysm restricted to the juxtarenal segment of the aorta, and not in continuity with the infrarenal lesion. While there have been reports both of true aneurysms arising independently in the abdominal (infrarenal) and thoracic (suprarenal) aortic segments, and of false aneurysms arising secondary to abdominal aortic repair (at the suture line or as dilatations of residual aneurysmal tissue), we believe our case unusual in that the new aneurysm was a discrete and “true” thoracoabdominal dilatation arising just above the renal arteries and terminating just below the superior mesenteric artery. This strictly juxtarenal dilatation conforms better to a descriptive pattern for atherosclerotic occlusive disease than it does to the standard scheme for classifying thoracoabdominal aortic aneurysms.
