Occasionally, standard stent grafts are not usable in emergency aortic bleeding, and custom-made stent grafts are not practical as a replacement. We describe a novel technique for the repair of such aneurysms by using the catheter-delivered liquid to solid embolic agent Onyx (Micro Therapeutics Inc., Irvine, CA). Two patients with ruptured aortic aneurysm, where endovascular or open repair was not considered as feasible, were treated by internal sealing of the aneurysm with Onyx, resulting in stoppage of bleeding and further expansion of the aneurysm-the plugging and sealing technique.

Larzon et al. (2010) conducted a case report in Ruptured aortic aneurysm with acute aortic bleeding (n=2). Internal sealing with catheter-delivered liquid to solid embolic agent (Onyx) was evaluated on Stoppage of bleeding and further expansion of the aneurysm. Internal sealing with the catheter-delivered embolic agent Onyx stopped acute bleeding and aneurysm expansion in 2 of 2 (100%) patients with inoperable ruptured aortic aneurysms.
