Original Excluder component overlap from proximal or distal extension during initial repair not correlated with aneurysm sac shrinkage

Original Excluder aneurysm sac diameter change not correlated with increased overlap. Length of overlap of patients (n = 67) with baseline overlap from the contralateral gate (white circles) and patients (n = 27) with additional overlap from extra components (black squares) plotted against change in aneurysm sac diameter does not show any correlation between increased length of overlap and decrease in aneurysm sac diameter.

Original Excluder aneurysm sac volume change not correlated with increased overlap. Length of overlap of patients (n = 67) with baseline overlap from the contralateral gate (white circles) and patients (n = 26) with additional overlap from extra components (black squares) plotted against change in aneurysm sac volume does not show a correlation between increased length of overlap and decrease in aneurysm sac volume.

Percentage aneurysm sac overlap not correlated with sac diameter change. Patients with additional overlap from baseline (n = 26, black squares) who had higher percentage of graft overlap within the aneurysm sac were not protected from aneurysm sac expansion. They did have a significantly higher percentage of graft overlap (26.2% ± 14.1% vs 18.6% ± 5.5%, P = .0097) than patients with baseline overlap from the contralateral gate (white circles). Few patients had extensive graft overlap.
