Aneurysm Stenting and Coiling

Live Aneurysm Coiling

Aneurysm Coiling with Stent Assisted Technique

A catheter is inserted through the artery to the site of the aneurysm, usually originating from the groin. The stent is deployed, and catheter is moved into the aneurysm, at which point the coil is released to fill the space. The coils induce clotting (embolization) of the aneurysm and prevent blood from entering.

This picture shows stent inside the vessel to help keep coil mass inside aneurysm, and ensure its total occlusion.

Flow Diverter (Pipeline)

A catheter is inserted through the artery to the site of the aneurysm, usually originating from the groin. The pipeline embolization device is deployed, and catheter is removed. The the remaining stent induces stagnation of blood flow to the aneurysm. Over time clotting will occur and the aneurysm will shrink eventually forming a normal blood vessel.

This picture shows the pipeline embolization device (stent) stretching across the aneurysm neck and protecting it from the blood flow, which will lead to its occlusion.
