ABSTRACT
Operations upon the juxta-and suprarenal aorta and the visceral branches of the upper abdominal aorta are performed much less frequently than reconstructions confined to the infrarenal aorta and its pelvic and extremity branches. There is evidence that more juxtarenal aneurysms are being diagnosed and repaired in absolute numbers (1). The sophistication of modern imaging modalities allows more detailed and easier assessment of the paravisceral aorta than in years past, and there is more of a trend to longitudinal follow-up by vascular surgeons now than previously. In addition, endovascular treatment of infrarenal abdominal aortic aneurysms is currently performed for anywhere from 4080% of patients undergoing aneurysm repair at referral centers. A larger percentage of the aortic aneurysms now repaired conventionally are juxta-or suprarenal. In the recent series from the Cleveland Clinic, the repair of juxtarenal aneurysms accounted for 10.8% of their total repairs in 1995 and 31.7% in 2000 (2). This relative increase in juxtarenal reconstructions reflects the active endovascular practice of those surgeons for the treatment of infrarenal aortic aneurysms.
