Abdominal aortic aneurysm with perianeurysmal fibrosis: Experience from 11 Swedish vascular centers ☆ ☆☆

Abstract Case records of 2026 patients operated on because of abdominal aortic aneurysms from 11 Swedish Vascular Centers were reviewed and revealed 98 cases (4.8%) of inflammatory abdominal aortic aneurysm. Also included in this case-control study was an analysis of a randomized group of 82 patients from the same centers who had noninflammatory abdominal aortic aneurysms. Four inflammatory aneurysms were ruptured, compared with 16 in the noninflammatory group ( p 50 mm; p p p = 0.03). In summary, inflammatory abdominal aortic aneurysms were more frequently symptomatic, were less likely to have ruptured and more frequently exhibited elevated erythyrocyte sedimentation rates or creatinine levels. Renal function abnormalities in patients with inflammatory abdominal aortic aneurysms were not influenced by the operative techniques employed against the ureter. (J VASC SURG 1991;13:231-9.)
