Simionescu et al. delivered 1–3, 4, 6-pentagalloylglucose (PGG) via a weeping endovascular balloon to stabilize elastin and collagen in a swine AAA model (elastase/collagenase and CaCl2) with not only attenuation of AAA but also reduction in aortic diameter (124). Here, ELN is linked to triple-A syndrome.
