Formatted Abstract/Summary
Results of endovascular aneurysm repair (EVAR) may be gender dependent. Between September 1997 and September 2001, 118 AneuRx™ aortic grafts were placed for aneurysmal disease. During this period, 17 females and 101 males were treated with this device. A prospective database was maintained and supplemented with retrospectively gathered information to evaluate early and mid-term end points. A total of 113 devices were deployed in 118 attempts. Length of procedure was greater for females (3.3 ± 1.75 vs. 2.3 ± 0.8 hr, p = 0.05) and they were more likely to have significant arterial dissections (12% vs. 1%, p = 0.05). The mortality rates at 1 month were 12% for females and 0% for males (p = 0.02); the complication rates at 1 month were 41% for females and 15% for males (p = 0.02). Although technical success was not significantly different between the sexes, assisted primary technical success (requiring endovascular assistance) and assisted secondary technical success (requiring open surgical assistance) were significantly different (71% vs. 96%, p = 0.003; and 76% vs. 98%, p = 0.004, respectively). Clinical success at 1 month was 59% for females and 84% for males (p = 0.02). This difference was also significant when assessing 1-month assisted primary clinical success (59% vs. 90%, p = 0.003) and assisted secondary clinical success as well (71% vs. 96%, p = 0.003). Clinical success and assisted primary clinical success were not different at 6- or 12-month intervals, however, assisted secondary clinical successes differed at both time intervals (56% vs. 83%, p = 0.02; and 56% vs. 81%, p = 0.05, respectively). As-yet undetermined factors appear to predispose females to complications and technical difficulties in the short term. Endovascular and open procedures required to achieve ongoing clinical success in the following months appear to favor males to a greater degree than females.
