SpletAt the first post-EVAR CTA, the mean SAL was 31.9±15.6 mm, and the mean EID was 19.5±11.8. At the last follow-up CTA, there was a significant decrease in apposition of 10.5±14.1 mm (P<0.001) and a significant increase in EID of 5.3±9.5 mm (P<0.001). A type Ib endoleak developed in three patients due to a reduced SAL. SpletVariability was low for calculation of endograft diameter (RC 2.3 mm), fabric distances (RC 5.2 to 5.7 mm), and shortest apposition length (RC 4.1 mm), which was the same as …
