The Powerlink system for endovascular abdominal aortic aneurysm repair: Six-year results

The Kaplan-Meier survival curves for the Powerlink and control groups are presented in the figure below. The log-rank test was not statistically significant with P = .5065. The observed survival rates and 95% confidence limits of the rates are presented in Table IX.

Kaplan-Meier AAA-related survival curves for Powerlink and control groups through 72 months.

Kaplan-Meier curve of freedom from device-related hospitalization in Powerlink group.

Kaplan-Meier curve of freedom from major adverse events through 72 months in Powerlink and control groups. The log-rank test of the difference in freedom from major adverse event curves between the two treatment groups was not statistically significant (P =.5251).

Kaplan Meier analysis of freedom from endoleak through 72 months. The curve terminates at 72 months with detection of last endoleak.

A, Aneurysm sac diameter reduction over time in Powerlink group. Error bars represent standard deviation. B, Aneurysm sac volume reduction over time in Powerlink group. Error bars represent standard deviation.

Aneurysm sac straightening over time. The MMS reconstructions demonstrate a 22.6° sac angle reduction between 1 month and 3 years.
