Abstract

We assessed aneurysm neck diameter change after endovascular abdominal aortic aneurysm repair (EVAR) and its relationship to stent-graft diameter. Ninety-eight patients with abdominal aortic aneurysm who underwent EVAR were studied with multislice computed tomography following a standardized protocol. A preoperative study and immediate postoperative, 6-month, 1-year, and 2-year follow-up studies were performed. The aneurysm neck was measured from adventitia to adventitia, 6 mm below the lowermost renal artery, in planar images performed perpendicular to the vessel axis (real axial section). Baseline and follow-up neck diameters were compared with stent-graft diameters. For statistical analysis, a one-way analysis of variance with repeated measures was used. Pearson's correlation coefficient was used to examine the correlation between the change in neck diameter and stent-graft diameter. The average neck diameter was 22.38 mm (range 16-32.5) on the preoperative study and 23.35 mm (17-33.9) on the immediate postoperative, 24.35 mm (18.2-34.5) on the 6-month, 24.36 mm (18-34.5) on the 1-year, and 24.39 mm (17.8-35.7) on the 2-year follow-up. The mean device diameter was 24.08 mm (20-32). A significant increase in average neck diam...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
