Abstract | BACKGROUND: METHODS: From January 2003 to August 2006, consecutive patients treated with Neuroform stent for intracranial aneurysms were prospectively enrolled. Information on patient demographics, cerebrovascular risk factors, aneurysm size and location were collected. Technical and clinical complications as well as clinical outcomes were measured. Data were analyzed retrospectively using SPSS software version 11.5. RESULTS: Successful deployment of the stent, in the target artery, was achieved in 65/67 (97%) patients. Stent deployment failed in two cases and the migration of stent developed in one during coiling. Postoperative thromboembolic events developed in three patients. These three patients possessed hyperactive platelets, and were treated with intravenous eptifibatide. Intraoperative rupture of aneurysm developed in one patient, which was secured by subsequent coiling. Majority of the patients had good outcomes GOS (Glasgow Outcome Score) 1 or NIHSS (National Institute of Health Stroke Scale) 0 in 63/67 (94%), GOS 2 or NIHSS 2 in one patient and GOS 3 or NIHSS 4 was observed in three cases. CONCLUSION: Despite a low rate of intraoperative complications, post-procedural thromboembolic events were common in Neuroform stent-treated patients, which might be associated with hyperactive platelets. Further studies are warranted to identify any potential relationship between post- stent hyperactive platelets and thromboembolism.
