A coil herniation refers to part of a detachable coil prolapsing out of the aneurysmand into the parent artery. It is an uncommon complication, and is typically seen at the end of the embolisation procedure. A number of factors are contributory, including 1:
• wide aneurysm neck
• instability of the coil in the aneurysm sac
• excessive embolisation
• microcatheter removal
• the coil being pushed out by subsequent coil embolisation
The herniated coil loops can result in compromise to flow in the vessel or distal thromboembolic complications.
