The authors sought to determine whether flow diversion with the Pipeline Embolization Device (PED) can approximate microsurgical decompression in restoring function after cranial neuropathy following carotid artery aneurysms.This multiinstitutional retrospective study involved 45 patients treated with PED across the United States. All patients included presented between November 2009 and October 2013 with cranial neuropathy (cranial nerves [CNs] II, III, IV, and VI) due to intracranial aneurysm. Outcome analysis included clinical and procedural variables at the time of treatment as well as at the latest clinical and radiographic follow-up.Twenty-six aneurysms (57.8%) were located in the cavernous segment, while 6 (13.3%) were in the clinoid segment, and 13 (28.9%) were in the ophthalmic segment of the internal carotid artery. The average aneurysm size was 18.6 mm (range 4-35 mm), and the average number of flow diverters placed per patient was 1.2. Thirty-eight patients had available information regarding duration of cranial neuropathy prior to treatment. Eleven patients (28.9%) were treated within 1 month of symptom onset, while 27 (71.1%) were treated after 1 month of symptoms. The overall rate of cranial neuropathy improvement for all patients was 66.7%. The CN deficits resolved in 19 patients (42.2%), improved in 11 (24.4%), were unchanged in 14 (31.1%), and worsened in 1 (2.2%). Overtime, the rate of cranial neuropathy improvement was 33.3% (15/45), 68.8% (22/32), and 81.0% (17/21) at less than 6, 6, and 12 months, respectively. At last follow-up, 60% of patients in the isolated CN II group had improvement, while in the CN III, IV, or VI group, 85.7% had improved. Moreover, 100% (11/11) of patients experienced improvement if they were treated within 1 month of symptom onset, whereas 44.4% (12/27) experienced improvement if they treated after 1 month of symptom onset; 70.4% (19/27) of those with partial deficits improved compared with 30% (3/10) of those with complete deficits.Cranial neuropathy caused by cerebral aneurysm responds similarly when the aneurysm is treated with the PED compared with open surgery and coil embolization. Lower morbidity and higher occlusion rates obtained with the PED may suggest it as treatment of choice for some of these lesions. Time to treatment is an important consideration regardless of treatment modality.

Recent randomized trials, have demonstrated that endovascular therapy improves outcomes in patients with an acute ischemic stroke from a large vessel occlusion (LVO). Sub-group analysis of the MR CLEAN study found that patients undergoing general anesthesia (GA) for the procedure did worse than those with non-general anesthesia (non-GA). Current guidelines now suggest that we consider non-GA over GA, without large, randomized trials specifically designed to address this issue. We sought to review our experience and outcomes in a program where we routinely use GA in patients undergoing mechanical thrombectomy with similar techniques.Patients with anterior circulation strokes who received intravenous tissue plasminogen activator (IV-tPA) and endovascular stroke therapy were included in the analysis. National Institutes of Health Stroke Scale (NIHSS) on admission and discharge, and modified Rankin scales (mRS) at discharge were recorded and compared to the outcome measurements of MR CLEAN.60 patients were identified; 39 males and 21 females with a mean age of 62 (range of 29 to 88). 47 patients were transferred from outside primary stroke centers, while 13 patients presented directly to our institution. Median NIHSS on admission was 15. The median time of symptom onset to endovascular therapy was 265 minutes, with an interquartile range of 81 minutes. Using the thrombolysis in cerebral infarction (TICI) scale, recanalization of TICI 2b - 3 was achieved in 76.4% of recorded patients (42/55 recorded). At discharge, mortality was 16.7% (10/60), median NIHSS was 5 and 38.3% (23/60) of patients had a mRS score of 0 - 2.General anesthesia does not worsen outcome in patients undergoing mechanical thrombectomy when compared to historical subgroups. Despite a longer time from symptom onset to treatment, our outcomes for patients receiving GA compare favorably to the GA and non-GA groups in MR CLEAN.

Recombinant factor VIIa (rFVIIa) can be used for rapid INR normalization in life-threatening hemorrhage in anticoagulated patients. Dosing is unclear and may carry thromboembolic risks. We reviewed the use of rFVIIa at a comprehensive stroke and cerebrovascular center to evaluate dose effectiveness on INR reduction and thromboembolic complications experienced. The primary endpoint was to review the efficacy of rFVIIa in lowering INR. Secondary endpoints included doses used and adverse effects caused by rFVIIa administration. Forty-one percent of patients presented with a subdural hemorrhage. The mean INR prior to rFVIIa administration was 3.5 (0.9-15) and decreased to 1.13 (0.6-2). The mean dose of rFVIIa given was 73 mcg/kg (24 mcg/kg). Two patients (3%) experienced a thromboembolic event. Recombinant factor VIIa appears to lower INR without significant thromboembolic complications.

BACKGROUND: The Enterprise Vascular Reconstruction Device and Delivery System (Cordis; the Enterprise stent) was approved for use in conjunction with coiling of wide-necked aneurysms in 2007. No published long-term aneurysm occlusion or complication data exist for the Enterprise system. OBJECTIVE: We compiled data on consecutive patients treated with Enterprise stent-assisted coiling of aneurysms from 9 high-volume neurointerventional centers. METHODS: A 9 center registry was created to evaluate large volume data on the delayed safety and efficacy of the Enterprise stent system. Pooled data were compiled for consecutive patients undergoing Enterprise stent-assisted coiling at each institution prior to May 2009. RESULTS: Two-hundred twenty-nine patients with 229 aneurysms, 32 of which were ruptured aneurysms, were included in the study. Mean clinical and angiographic follow-up was 619.6 ± 26.4 days and 655.7 ± 25.2 days, respectively. Mean aneurysm size was 9.2 ± 0.4 mm. Fifty-nine percent of patients demonstrated 100% coil obliteration and 81% had 90% or higher occlusion at last follow-up angiography. A total of 19 patients (8.3%) underwent retreatment of their aneurysms during the follow-up period. Angiographic in-stent stenosis was seen in 3.4% and thromboembolic events occurred in 4.4%. Overall, 90% of patients who underwent Enterprise-assisted coiling had a modified Rankin Scale score of 2 or less at last follow-up. A poor modified Rankin Scale score was strongly associated with rupture status (P < .001). CONCLUSION: Although this study is limited by its retrospective nature, the Enterprise stent system appears to be an effective, safe, and durable treatment for intracranial aneurysms when used in conjunction with coiling.

Object. Ventriculitis related to external ventricular drain (EVD) placement is a significant source of morbidity in neurological intensive care patients. Current rates of EVD-related infections range from 2% to 45% in the literature. The authors sought to determine if a 2-octyl cyanoacrylate adhesive would result in lower infection rate than standard semiocclusive dressings. Methods. The authors tracked ventriculitis rates via CSF cultures among 259 patients whose EVD sites were dressed with sterile semiocclusive dressings and underwent routine sterile dressing exchanges every 48 hours. They analyzed data obtained in an additional 113 patients whose EVD sites were dressed one time with a surgical adhesive, 2-octyl cyanoacrylate. Results. Ventriculitis rate in patients with standard bioocclusive dressings and wound care was 15.1%, whereas that in patients with a 2-octyl cyanoacrylate dressing was 3.54% (p = 0.002). Staphylococcus genus accounted for 79.5% of instances of ventriculitis among patients with bioocclusive dressings and routine wound care, whereas it accounted for 25.0% of the instances of ventriculitis among patients with a liquid polymer sealant dressing. A 90% reduction in Staphylococcus infection completely accounts for the observed effect (p = 0.04). Conclusions. The one-time application of 2-octyl cyanoacrylate to EVD wounds and exit sites provided superior protection against EVD-related ventriculitis compared to conventional EVD-site wound care. Likely this protection results from a barrier to the entry of gram-positive skin flora along the EVD exit tract. The results should be validated in a randomized trial. ©AANS, 2014.

BACKGROUND:: Emergency medical services (EMS) prenotification to hospitals regarding the arrival of patients who have had a stroke is recommended to facilitate the workup once the patient arrives. Most hospitals have the patient enter the emergency department (ED) before obtaining a head computed tomography (CT) scan. At Capital Health, prehospital stroke-alert patients are delivered directly to CT and met by a neurological emergency team. The goal of bypassing the ED is to reduce the time to treatment. OBJECTIVE:: To evaluate (1) door-to-CT and door-to-needle time in patients with an acute stroke who arrive as prehospital stroke alerts and (2) the accuracy of EMS assessment. METHODS:: A prospective database of all prehospital stroke alert patients was kept and data retrospectively reviewed for patients who were seen between July 2012 and July 2013. RESULTS:: Between July 2012 and July 2013, 141 prehospital stroke alerts were called to our emergency department, and the patients were stable enough to bypass the ED and go directly to CT. EMS assessment of stroke was accurate 66% of the time, and the diagnosis was neurological 89% of the time. The average time between patient arrival and acquisition of CT imaging was 11.8 minutes. Twenty-six of the 141 patients (18%) received intravenous tissue plasminogen activator. The median time from arrival to intravenous tissue plasminogen activator bolus was 44 minutes. CONCLUSION:: Trained EMS responders are able to correctly identify patients who are experiencing neurological/neurosurgical emergencies and deliver patients to our comprehensive stroke center in a timely fashion after prenotification. The prehospital stroke alert protocol bypasses the ED, allowing the patient to be met in CT by the neurological ED team, which has proven to decrease door-to-CT and door-to-needle times from our historical means.

The patient is a 60-year-old woman who presented to her primary care physician with new onset of headache. She was neurologically intact without cranial nerve deficit. An outpatient CT angiogram (CTA) revealed no subarachnoid hemorrhage, but showed a right-sided posterior communicating artery aneurysm measuring 11 mm by 10 mm. Digitally subtracted cerebral angiography confirmed these measurements and showed that the aneurysm was amenable to endovascular coil embolization. The patient underwent aneurysm coiling without complication and was discharged to home on postoperative Day 1. The video can be found here: http://youtu.be/MjOc3Zpv2K8 .

TREVO 2 showed the Trevo stent retriever to be more successful for revascularization than Merci for acute stroke intervention in patients treated within 8 hours of symptom onset. These results led to US Food and Drug Administration approval of Trevo.To report the first postmarket experience with Trevo since US Food and Drug Administration approval at a single high-volume comprehensive stroke center in the United States.A retrospective analysis of prospectively collected data was conducted in patients who underwent intervention for ischemic stroke with the Trevo device. Trevo was used alone or in conjunction with other intra-arterial devices. Two groups of patients were identified: those with symptom onset within (group 1) and those with symptom onset beyond (group 2) 8 hours. Recanalization, outcome, symptomatic intracranial hemorrhage, and in-hospital and 90-day mortality were assessed.Fifty-two patients were identified, 27 in group 1 and 25 in group 2. Thrombolysis in Cerebral Infarction grade 2 to 3 revascularization was achieved in 93% of group 1 and 84% of group 2 patients. In-hospital mortality and symptomatic intracranial hemorrhage rates were 3.8% and 12% for groups 1 and 2, respectively. Ninety-day mortality was 15% and 24% for groups 1 and 2, respectively. In groups 1 and 2, 48% and 42% of patients, respectively, had good outcomes (modified Rankin Scale score, 0-2), and 50% in both groups of patients achieved Thrombolysis in Cerebral Infarction grade 3 revascularization. Group 2 had longer revascularization times and required adjuvant devices more frequently.Our postmarket experience shows that in highly selected patients Trevo is safe and effective, even beyond 8 hours, despite longer procedure times and the need for adjuvant devices.
