title: Inflammatory abdominal aortic aneurysm: report of seven cases.
abstract: We reviewed 575 cases of abdominal aortic aneurysm (AAA) repair performed in our institution from 1979 to 2010. In this group, 7 (1.2%) patients (mean age, 72.6 years) had evidence of inflammatory AAA (IAAA). Mean aneurysmal diameter was 70.4 mm as measured on CT, and the mantle sign was present in all cases. They were male smokers. Two patients had hydronephrosis, and required a ureteral stent before surgery. All patients underwent laparotomy, and no perioperative deaths occured. We suggest that operative technique should be modified to avoid excessive dissection on both the proximal and distal sides of the IAAA.
