Nitroglycerin mediated dilatation (NMD) and abdominal aortic aneurysm (AAA) progression. (A) There was no correlation between AAA size and NMD. (B) NMD did not deteriorate under AAA surveillance. Ethically, the NMD protocol could not be carried out in most patients with large AAAs scheduled for surgery, as the side effect of hypotension in this setting could potentially have complicated clinical management. As such, no comparison could be made for the pre- and post-operative NMD measurements.
