[Endovascular stent implantation in treatment of intracranial wide-necked aneurysms].
OBJECTIVE
To evaluate the effectiveness and feasibility of treatment of intracranial wide-necked aneurysms with a new technique of Neuroform self-expanding stent combined with detachable coil.


METHODS
A retrospective analysis of thirty patients with intracranial wide-necked aneurysms, 14 males and 16 females, aged 48 (18-68), wide-necked aneurysms, underwent occlusion of aneurysms using Neuroform self-expanding stent combined with detachable coil.


RESULTS
21 of the 30 aneurysms were completely occluded (70%) and 9 of the 30 aneurysms were incompletely occluded (30%) after initial coils embolization. Thromboembolic events were found in one case and migration of stent in two cases. Clinical follow-up performed in 29 patients showed that only one patient had permanent mild hemi-paralysis. Twenty-one patients were followed up for 6-12 months, 7 of which needed second treatment and 4 of which showed complete occlusion.


CONCLUSIONS
A flexible device, Neuroform self-expanding stent can be safely maneuvered through tortuous intracranial vessels, enabling the endovascular treatment of complex wide-necked aneurysms. The new technique of Neuroform stent combined with detachable coil increases the early outcome of intracranial wide-necked aneurysm.
