O-020 Treatment of intracranial aneurysms with pipelinetm flex embolization device with shield technologytm : angiographic and safety outcomes at 1 year follow-up
Conclusions The PFLEX study is the first prospective study to evaluate the use of the Pipeline Shield device. The results from the study are comparable to previously published results with the earlier generation devices, and demonstrate that the Pipeline Shield device is safe and effective for treatment of intracranial aneurysms.

O-035 Risk factors for delayed deterioration after cerebral venous thrombosis: a model to identify patients for early aggressive endovascular therapy
Conclusion We found that decreased mental status, seizure activity, papilledema, number of involved sinuses, sodium level, and platelet level to be the most important factors in predicting deterioration after CVT. This group may represent a subset of patients in who early thrombectomy may be considered. Further prospective trials are needed to confirm this hypothesis.

E-080 Endovascular stenting for idiopathic intracranial hypertension: a single-institution experience
Conclusion IIH is an uncommon condition with presenting symptoms that are relatively nonspecific. Though medical therapy is first-line, an important subset of patients who experience IIH secondary to dural sinus stenosis are commonly refractory to medications alone. DSS is becoming a more commonly used therapy for treatment of this subpopulation. This study demonstrates that stenting is an effective procedure that can be performed with good technical success and minimal complications in specialized high volume stroke centers. Further research comparing DSS to ONSF and CSF shunting is required to determine the relative effi...

E-082 Aggressive endovascular management of massive dural venous sinus thrombosis in the setting of acute myelogenous leukemia
Conclusion DVST is an uncommon cause of stroke. The appropriate diagnosis is imperative as the treatment for DVS is vastly different from the treatment of arterial stroke. Patients who suffer from DVST have a good prognosis and often achieve complete recovery. This case demonstrates the utility of more invasive endovascular treatments for extreme cases that fail to improve, or worsen, following a trial of conventional care. When thrombolysis and thrombectomy alone were not successful, stenting of an underlying dural sinus stenosis was ultimately required for successful recanalization. Disclosures: D. Leonard: None. A. Ha...

E-043 Reversible Cerebral Vasoconstriction Syndrome: Non-invasive Imaging Findings and Angiographic Evaluation
We present indirect findings on non-invasive imaging, such as transient cerebral edema, convexal subarachnoid hemorrhage, intraparenchymal hemorrhage and cerebral. Direct signs of single or multivessel arterial vasoconstriction are seen on CTA, MRA and confirmed on DSA. Reversibility of the vasoconstriction is demonstrated after intra-arterial administration of calcium channel blocker. Conditions such as diffuse atherosclerotic arterial narrowing, vasculitis, posterior reversible encephalopathy, cerebral edema secondary to venous congestion and vasospasm secondary to aneurysmal subarachnoid hemorrhage were among the pathol...

P-021 Very Delayed Monocular Blindness Following Flow Diversion Treatment of Ophthalmic Artery Aneurysm
ConclusionMonocular vision loss remains a risk, even months to years following flow diversion of ICA aneurysms.

Monotherapy with stenting in subarachnoid hemorrhage (SAH) after middle cerebral artery dissection
We describe a young patient who presented with acute headache from a subarachnoid hemorrhage that was ultimately determined to be due to a vascular dissection in the middle cerebral artery. The initial angiogram showed vascular irregularities in this area with stenosis. Repeat imaging 4 days after presentation identified a pseudoaneurysm proximal to the stenosis. The patient was successfully treated with a self-expanding nitinol stent and followed up with serial angiography during postoperative recovery in the hospital; additional angiograms were performed approximately 1 and 6 months after treatment. Serial angi...

Patient-reported outcome measures for patients with cerebral aneurysms acquired via social media: data from a large nationwide sample
Conclusions Despite this novel study design, we obtained results comparable to prior studies. These results suggest that many patients with ruptured cerebral aneurysms, regardless of whether they are >2 years after the event and/or free of physical impairment, struggle with a poor quality of life. The latency, scale, and low cost of this study design may accelerate future cerebral aneurysm PROM research.

E-075 neurosarcoidosis presenting as aneurysmal subarachnoid hemorrhage: an interesting case and novel treatment
Neurosarcoidosis, the term used for sarcoidosis involving the central nervous system, represents an uncommon form of sarcoidosis, found in a 5% of patients with systemic sarcoidosis. Clinically evident cerebrovascular involvement in neurosarcoidosis has been reported but appears to be an extremely rare manifestation of neurosarcoidosis. The literature describes these cerebral vasculopathic changes as areas of stenosis and/or vascular irregularity, with clinical manifestations including headache, ischemic stroke, and parenchymal hemorrhage. Neurosarcoidosis has even been described as the etiology for a case of moyamoya synd...

E-007 Unusual Two Cases of Dissecting Cervical Internal Carotid Artery Pseudo-aneurysm with Symptomatic Intracranial Aneurysm
Conclusions In the evaluation of suspected intracranial aneurysm who present with headache with neck pain, a catheter cerebral angiogram not only will clearly define the correct morphology of intracranial aneurysm but also will appropriately identify the presence of life threatening cervical ICA abnormalities. Additionally, presence of an unusual cervical ICA anatomy with DP may warrant further evaluation of intracranial blood vessel of same territory. Using endovascular strategies, both extracranial and intracranial DP could be treated. However, long-term follow-up and outcome is unknown. Further studies are required. Di...
