Embolization of Acutely Ruptured and Unruptured Wide-Necked Cerebral Aneurysms Using the Neuroform2 Stent without Pretreatment with Antiplatelets: A Single Center Experience

Abstract

BACKGROUND AND PURPOSE: The Neuroform2 stent has been increasingly used in the stent-assisted coiling of wide-necked cerebral aneurysms, mostly after pretreatment with antiplatelet drugs. We retrospectively analyzed our results of stent-assisted coiling without pretreatment with antiplatelets.

METHODS: We used 50 Neuroform2 stents in the treatment of 54 aneurysms without pretreatment with antiplatelets. Anticoagulation included intraprocedural heparin, nadroparin for 3 days, clopidogrel for 3 months, and aspirin for 6 months.

RESULTS: Forty-nine stents were successfully deployed, and 52 of 54 aneurysms coiled (51 totally occluded and 1 subtotally). There was only one case of intraprocedural thrombus formation that was easily treated with recombinant tissue plasminogen activator. No serious hemorrhagic complications occurred during the follow-up period, and all 18 patients whose aneurysms have been controlled with angiography were found to have patent stents without stenosis and no aneurysm recanalization. No aneurysm rebleeding has occurred.

CONCLUSION: We believe that stent-assisted coiling with the Neuroform2 stent is very effective and safe without pretreatment with antiplatelets in ruptured as well as in unruptured aneurysms.
