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

Objective: 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.

Clinical Presentation: 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.

Technique: 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.

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