Key result
Contrast extravasation (leak) into the aneurysmal sac following endoluminal repair was significantly associated with a progressive increase in abdominal aortic aneurysm diameter (P=0.001).
Why the study?
Does successful endoluminal repair without leak reduce AAA diameter compared to repair with leak in patients with abdominal aortic aneurysms?

Endoleak may warrant intensified post-EVAR surveillance; leaves open whether sealing alters sac expansion.

Does successful endoluminal repair without leak reduce AAA diameter compared to repair with leak in patients with abdominal aortic aneurysms?
p-value: p=0.001
Successfully excluded abdominal aortic aneurysms diminish in size following endoluminal repair, whereas those that continue to increase in size are highly associated with an undetected leak.
May et al. (1995) conducted a cohort in Abdominal aortic aneurysms (n=30). Contrast extravasation (leak) into the aneurysmal sac vs. No extravasation of contrast was evaluated on Progressive increase in AAA diameter (p=0.001). Contrast extravasation (leak) into the aneurysmal sac following endoluminal repair was significantly associated with a progressive increase in abdominal aortic aneurysm diameter (P=0.001).
