The Use Of Neuroform Stents In The Treatment Of Intracranial Wide-necked Carotid Artery Aneurysm Embolization

Objectives To evaluate the effect of Neuroform stents in the occlusion of wide-necked intracranial aneurysms.Method 12 patients identified as a wide-necked intracranial aneurysms were evaluated for stent-assisted coiling. Neuroform microdelivery stent system is led into the parent artery.Through the coaxial catheter a stent is placed across the aneurysm neck and subsequent coiling of the sac.The patients were fully heparinized 48 h post-operation and were administered with aspirin 300mg/d and clopidogrel(Plavix)75mg/d orally for one month.Thereafter aspirin 300mg/d was maintained for 6months.Results 9 patients had complete occlusion after deployment of a stent,2 patients with wide-necked carotid artery aneurysm had incomplete occlusion(95%).1 patient with posterior communicating artery aneurysm had vasospasms after deployment of the stent and occlusion was abandoned and treatment diverted to second treatment.After 6 months,neurovascular angiography of 4 of the patients indicated that the aneurysm had disappeared and the parent arteries were free.Conclusion Neuroform stents may overcome technical limitations in current endovascular therapy by improving the occlusion of wide-necked aneurysms while protecting the parent vessel.
