Neuroform Stent Applications in Ruptured Intracranial Aneurysms with Small Parent Vessels

Abstract

The Neuroform stent is a device specifically designed for use in cerebral vessels and is increasingly being used in the embolization of broad-necked aneurysms, but long-term results are unsatisfactory. Reconstructive treatments using stents improve the occlusion rate and protect parent vessels. Stent-assisted coiling of broad-necked cerebral aneurysms is a technique that has rendered most aneurysms amenable to coiling. Recently, the use of stent-assisted coiling with preservation of the parent vessel lumen has been described in some series. Several studies have shown that with the advances in device technology intracranial stenting is feasible even in the distal part of the ICA. But, endovascular treatment of these aneurysms (small parent vessel less than 2.0 mm) in Neuroform stent-assisted coiling has no clinical applications. These lesions have seemed more difficult to treat than other aneurysms because of subsequent thrombus formation and vessel trauma after stent deployment and navigation. The purpose of this study was to review the safety and durability of our aneurysms treated with stent-assisted coiling of ruptured aneurysms with small parent vessesl.

Stent-Assisted Embolization for Acutely Ruptured Aneurysm

“…The Neuroform Atlas was reportedly effective for acutely ruptured aneurysms. [7][8][9] As the percentage of metal coverage is not high in these stents, they can be used safely even in the acute phase wherein thrombotic complications are a concern due to the inadvisability of strong antiplatelet therapy. 10,11) Moreover, its open-cell design facilitates an easy expansion of the Neuroform Atlas within the aneurysm beyond the parent artery diameter (Fig.…”
