Stent-Assisted Coiling of Wide-Necked Aneurysm

 

Angiogram shows an aneurysm with a wide neck. The shape of the aneurysm would make it difficult to pack with coils without some of the coils bulging into the artery.

3D rotational angiogram of the same aneurysm confirms its wide neck.

Another view of the 3D reconstruction of the aneurysm, again confirming the wide neck.

 

 

 

 

 

 

---

A Neuroform stent has been placed in the artery, spanning the wide aneurysm neck. The aneurysm has then been packed with coils and the stent keeps the coils in the aneurysm sac and out of the artery. The stent is a wire mesh tube made of wire so fine that it is hard to see on the angiogram—its ends are marked with four “dots”.
