Treatment of Ruptured and Nonruptured Aneurysms Using a Semisolid Iodinated Embolic Agent (Adv. Mater. 10/2022)

Endovascular Treatment In article number 2108266, Rahmi Oklu and co‐workers report an endovascular treatment for ruptured saccular aneurysms. In the cover image, blue represents the catheter inside the artery releasing the shear thinning hydrogel (in yellow) inside the aneurysm sac, rapidly achieving hemostasis. The magnified image of the hydrogel demonstrates its structure, with the dark brown spots indicating iodine. The inset in the lower right demonstrates rapid healing of the aneurysm neck and the fibroinflammatory response to the hydrogel leading the fibrotic replacement of the biomaterial.
