PURPOSE: To determine outcomes of aneurysmal common iliac arteries (aCIA) used for landing zones (LZs) during @entity439 repair (EVAR). METHODS: This single-center study retrospectively compared 57 EVAR @entity1 (mean age 72  8 years; 56 @entity1 ) with 70 aCIAs (diameter >= 20 mm) to 25 control EVAR subjects (mean age 73  7 years; 20 @entity1 ) with 50 normal ( <=15-mm) @entity29941 LZs treated consecutively during the same time interval. The @entity29941 LZ measurements were analyzed using random effects linear mixed models to determine diameter change over time. Life tables were used to estimate freedom from endoleak, reintervention, and all-cause mortality. RESULTS: The mean maximum preoperative @entity29941 diameter in the aCIA LZ group was 24.8  4.5 mm (range 20.0-47.3, median 23.9) vs 13.6  1.5 mm (range 9.2-15.0, median 13.9; p<0.001) in the controls. Nineteen aCIA LZs were treated outside the instructions for use of the device. Median follow-up in the aCIAs LZ cohort was 39.2 months [interquartile range (IQR) 15, 61] vs 49.3 months (IQR 36, 61) in the controls (p=0.06). The rate of aCIA LZ change (0.09 mm/mo, 95% CI 0.07 to 0.1) was significantly greater than controls (0.03 mm/mo, 95% CI -0.009 to 0.07; p<0.0001). No type Ib endoleaks developed in either group; however, aCIA LZ @entity1 had 6 (11%) iliac limb-related reinterventions. There were significantly more endograft-related reinterventions in the aCIA LZ @entity1 (n=10, 14%) compared with controls (n=2, 4%; p=0.06). There was no difference in mortality or freedom from any post-hospital discharge endoleak. CONCLUSION: Aneurysmal @entity29941 LZs used during EVAR experience greater dilatation compared with normal LZs, but no significant difference in outcome was noted in midterm follow-up. However, an increased incidence of graft limb complications or endograft-related reintervention may be encountered. Use of aCIA LZs appears to be safe; however, greater @entity1 numbers and longer follow-up are needed to understand the clinical implications of morphologic changes in these vessels when used during EVAR.
