Stent-jack technique in stent-assisted coiling of wide-neck aneurysms

To describe a variant of the stent-assisted coiling technique in the endovascular treatment of aneurysms with a dome-to-neck ratio less than 1.5.

This technique, named the stentjack technique, consisted of the deployment of a first coil before the delivery of a self-expandable stent across the aneurysm neck without detachment. Once the stent was deployed, the first coil was detached.

This maneuver enabled us to constrain the coil loops within the sac before detachment of the first coil, a coil that is often critical when dealing with broad-neck aneurysms. We successfully treated three patients harboring wide-neck aneurysms.

We found that the stentjack technique was helpful in the treatment of selective aneurysms with a dome-to-neck ratio smaller than 1.5.
