Figure 2: The biodegradable nanofiber‑covered stent was placed in a canine aneurysm model with complete occlusion of the aneurysm. (a) Anteroposterior angiography before the procedure shows an aneurysm (arrow) at the middle of the common carotid artery. (b) Dilation of the biodegradable nanofiber‑covered stent with a balloon. (c) Anteroposterior angiographic study obtained immediately after the procedure shows complete occlusion of the aneurysm without endoleak. (d) Follow‑up angiography 3 months after the procedure still shows the complete occlusion of the aneurysm, without obvious stenosis of the parent artery
