Treatment of a Vertebral Dissecting Aneurysm with Stents and Coils: Technical Case Report

Abstract

We applied a new technique to treat a dissecting aneurysm of the intracranial portion of the vertebral artery with a combination of stents and coils. Further work is required on the tracking, flexibility, and thrombogenic properties of diverse materials and devices. This evolving technology may play a role in the near future as the alternative of choice in some cases of aneurysm treatment via the endovascular route.

Rupture of a Vertebral Artery Dissecting Aneurysm Developing Immediately After Trapping of a Dissecting Aneurysm on the Contralateral Vertebral Artery -Case Report-

“…Guglielmi detachable coils may be positioned in the dissecting aneurysms after placing stents in the true lumen of the VAs to preserve normal blood flow and treat dissecting aneurysms. 5) This method seems to be more effective than conventional occlusion therapy of the parent arteries. However, this method is not proven since long-term results are not yet available.…”

Endovascular Treatment of Internal Carotid and Vertebral Artery Aneurysms Using Covered Stents

“…Although immediate aneurysmal occlusion can be seen after single stent placement for treatment of extracranial pseudoaneurysms, in some cases, 3-6 months or longer may pass before occlusion occurs. To achieve faster complete aneurysmal occlusion, the combination of stents and detachable coils has been suggested for extracranial, as well as intracranial aneurysms [2,52,53] and the combination is currently considered an alternative to single stent placement or other techniques such as the remodeling technique or parent vessel occlusion. Lanzino et al [52] reported 10 cases managed with stent-supported coil embolization; they achieved aneurysmal occlusion of more than 90% in eight patients.…”

Sole stenting of large and giant intracranial aneurysms with self-expanding intracranial stents—limits and complications

“…One patient that had no angiographic result 1 year after sole stenting remained in follow-up without further treatment, since her symptoms due to extradural ICA aneurysm were gradually resolving. Retrograde analysis of angiographic images led to a conclusion that the site of rupture may have been at the distal part of the aneurysm, near the neck, probably due to the Sole stenting was reported for the first time as an ancillary method to stent-assisted coiling [14,18], and is recently receiving attention as a planned definitive method of treatment of intracranial aneurysms. This method is appealing since modern intracranial stents are easily deployed, even in a stent-in-stent fashion, with low risk for vessel injury and short procedure times.…”
