ABSTRACT
BACKGROUND/OBJECTIVE: Cerebral angiography (CA) is increasingly used in clinical practice with advances in neurointerventional therapy. We present our CA experience performed by neurologists at an academic institution. METHOD: CA performed between July 2005 and March 2008 was reviewed. Major neurological outcome was defined as a new neurological deficit lasting >24 hours or worsening of pre-existing neurological deficit by 4 points on the National Institutes of Health Stroke Scale. Major non-neurological outcomes were defined as any death within 24 hours of the procedure, vascular injury requiring surgery, arteriovenous fistula, or pseudo-aneurysm formation and access site hematoma >5 cm, and/or requiring blood transfusion. RESULTS: In total 661 angiograms were performed over 30 months. CA indications were ischemic stroke in 210/661 (31.7%), hemorrhagic stroke in 321/661 (48.6%), trauma for 16/661 (2.4%), presurgical epilepsy workup 95/661 (14.3%), and other conditions 19/661 (2.9%). Mean age of the group was 49 +/- 18 years. Permanent neurological deficit occurred in .2% (1 patient) and reversible neurological deficits occurred in .2% (1/661). Major non-neurological complications occurred in .9% (6/661). All these rates were less than established guidelines. CONCLUSIONS: The safety and efficacy of CA performed by interventional neurologists is acceptable by current guidelines.

BACKGROUND/OBJECTIVE: Symptomatic thromboembolic events are the most common complications associated with aneurysm coiling, and carotid and intracranial stenting. Our objective is to assess the effect of aspirin (ASA) and clopidogrel dose and duration on platelet inhibition using a point of care assay in neurointerventional (NI) suite. METHOD: The dose, duration, and point of care platelet function assay data for clopidogrel and aspirin therapy were prospectively collected between February 2006 and November 2007. Inadequate platelet inhibition for ASA was defined as >or=550 ASA reaction units (ARU), and for clopidogrel was defined as

BACKGROUND AND AIM: Two independent post-approval registries have reported favorable periprocedural and short term outcomes with the use of the Wingspan stent for treatment of intracranial arterial stenosis. Data on long term clinical and imaging outcomes after Wingspan stent placement are limited. METHODS: All patients treated with the Wingspan stent in a single academic center from January 2006 to February 2008 were identified. Data on stenting indication, severity of stenosis, technical success, re-stenosis and clinical outcome were collected. RESULTS: 51 patients were treated with the Wingspan stent system for a symptomatic intracranial atherosclerotic stenosis of 50-99%. The technical success rate was 98%. The mean pre- and post-stent stenoses were 73 (11)% and 21 (7)%. Any stroke or death within 24 h of the procedure occurred in 1/51 (2%). The frequency of any stroke or death within 30 days or ipsilateral stroke beyond 30 days was 5/51 (10.0%) at a mean follow-up time of 14.6 months (range 8-30). The frequency of ≥ 50% re-stenosis on follow-up imaging was 7/29 (24%) at 8.6 (4.4) months (range 3-20); all were detected on the initial imaging within 3-6 months, and only one was symptomatic. CONCLUSION: The use of the Wingspan stent in patients with ≥50% symptomatic intracranial stenosis is associated with good long term clinical outcome. One stroke occurred after the first 30 days, suggesting a significant stabilization of the adverse event rate after the first month.

The authors identified predictors of functional disability and mortality after status epilepticus in a multivariate analysis of 83 episodes in 74 patients. Twenty-one percent (14/85) of episodes were fatal. Increased age (OR = 1.1; 95% CI, 1.0 to 1.1) and acute symptomatic seizures (OR = 6.0; 95% CI, 1.2 to 30.3) were predictors of mortality. Functional outcome at discharge deteriorated in 23% (16/69) of nonfatal episodes. Increased length of hospitalization (OR = 1.04; 95% CI, 1.0 to 1.1) and acute symptomatic seizures (OR = 3.9; 95% CI, 1.0 to 14.7) were predictors of functional disability.
