<h3>BACKGROUND AND PURPOSE:</h3> Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection is associated with hypercoagulability. We sought to evaluate the demographic and clinical characteristics of cerebral venous thrombosis among patients hospitalized for disease 2019 (COVID-19) at 6 tertiary care centers in New York City metropolitan area. <h3>MATERIALS METHODS:</h3> conducted a retrospective multicenter cohort study 13,500 consecutive COVID-19 who were between March 1 May...
Background The Penumbra system is effective for recanalization of the primary arterial occlusion (PAO) in acute stroke. However, clinical outcomes are not as promising. authors hypothesized that formation procedural distal emboli (PDE) during mechanical thrombectomy may lead to poorer patient outcomes. Design/methods A retrospective review patients with ischemic stroke treated was undertaken. Patients' outcome evaluated by comparing discharge National Institute Health scale and modified...
There is emerging evidence that COVID-19 can trigger thrombosis because of a hypercoagulable state, including large-vessel occlusion ischemic strokes. Bihemispheric stroke uncommon and thought to indicate an embolic source. Here, we examine the findings outcomes patients with bihemispheric in setting COVID-19.We performed retrospective cohort study at quaternary academic medical center between March 1, 2020, April 30, 2020. We identified all laboratory-confirmed severe acute respiratory...
Background:The DRAGON score, which includes clinical and computed tomographic (CT) scan parameters, predicts functional outcomes in ischemic stroke patients treated with intravenous tissue plasminogen activator (IV tPA).We assessed the utility of score predicting outcome receiving both IV tPA endovascular therapy.Methods: A retrospective chart review at our institution from February 2009 to October 2015 was conducted.All tomography angiography (CTA) proven large vessel occlusions (LVO) who...
Acute ischemic stroke (AIS) is a rare occurrence during pregnancy and the postpartum period. Existing literature evaluating endovascular mechanical thrombectomy (MT) for this patient population limited.The National Inpatient Sample was queried from 2012 to 2018 identify characterize pregnant patients (up 6 weeks following childbirth) with AIS treated MT. Complications outcomes were compared nonpregnant female MT other managed medically. Complex samples regression models propensity score...
Unruptured intracranial aneurysms measuring <7 mm in diameter have become increasingly prevalent due to advances diagnostic imaging. The most feared complication is aneurysm rupture leading a subarachnoid hemorrhage. Based on the current literature, 3 main treatments for an unruptured are conservative management with follow-up imaging, endovascular coiling, or surgical clipping. However, there remains no consensus best treatment approach. natural history of and risk factors must be...
Spontaneous nontraumatic intracerebral hemorrhage is associated with high morbidity and mortality. Given the risk of rapid neurological deterioration, early identification neuroimaging vital. Predictors outcome, such as spot sign score, can help guide management goals. Management should be aimed at prevention hematoma expansion, treatment increased intracranial pressure, secondary brain injury medical complications.
Cerebral arteriovenous malformations (AVMs) are a complex and heterogeneous pathology which require an understanding of the natural history these lesions, as well potential treatment options in order to manage them safely. While is agreed upon strategy for most ruptured AVMs, management unruptured AVMs continues be debated. More recently, this debate has been fueled by A Randomized Trial Unruptured Arteriovenous Malformations (ARUBA) trial attempts define risk AVMs. However, significant...
OBJECTIVE: Uncommon varied neurological presentations of VZV BACKGROUND: Meningoencephalitis with is rare. It can be seen in immunocompetent and immunocompromised patients.Neurological symptoms the absence rash are rare.Making a diagnosis recent dermatomal distribution challenging. METHODS: 50 year old female experienced urinary bowel retention numbness heel for three days. She had painful vesicular eruption on her right thigh eight weeks earlier. MRI neuraxis was normal.VZV PCR positive...
Objective: We report a case of delayed onset HIT in patient previously exposed to heparin with no adverse effects. Two weeks after his last exposure the developed resulting acute right CCA occlusion and other thrombotic events. Background: Delayed is an immune-mediated disorder where antibodies against heparin/platelet factor 4 complex formed persist for several days despite absence circulating thrombocytopenia hypercoagulable state. Heparin may predispose antibody formation but does not...

OBJECTIVE: We present the case of a patient presenting with ascending weakness initially involving bilateral lower extremities followed by proximal upper extremities. Neuroimaging confirmed anterior cerebral artery (ACA) distribution infarction due to presence azygous ACA anomaly. BACKGROUND: An is rare variant seen in approximately 0.4-1[percnt] population which two A1 segments join form single trunk. As result, there no communicating artery. Infarction within unilateral territory...
OBJECTIVE: We report a case of Progressive Multifocal Leukoencephalopathy (PML) in patient with untreated Chronic Lymphocytic Leukemia (CLL) BACKGROUND: multifocal leukoencephalopathy occurs exclusively patients impaired cell mediated immunity. PML has only been reported CLL after chemotherapy treatment. To our knowledge, this is the first infection who never received immunosuppressive DESIGN/METHODS: A 69 year old right-handed male prior history was admitted to hospital suffering his...
OBJECTIVE: To apply the DRAGON score to acute ischemic stroke patients receiving both IVtPA and endovascular therapy estimate correlation with outcome at discharge. BACKGROUND: As per 2015 AHA/ASA guidelines, for strokes should ideally be followed by within 6 hours of symptom onset. Originally described Strbian et al, is a 10 point scoring system that designates points based on: CT imaging findings, pre-stroke modified Rankin Scale (mRS), Age, Glucose level on admission, Onset-to-treatment...
Objective: We present a case of paradoxical air embolism leading to stroke related laser ablation accessory vein. Background: Less invasive procedures such as are being commonly used for treatment varicose veins. However infection, phlebitis, bruising, hematoma and paresthesias may occur. Laser generates heat intraluminal steam bubbles irreversible endothelial damage thrombosis. Air can be introduced during into systemic circulation after crossing through patent foramen ovale (PFO)...
Objective: To present a case of rapid clinical improvement in 2 hours and reversal sagging brainstem within 24 spontaneous intracranial hypotension associated with subdural collections after CT-guided large-volume epidural blood patch. Background: Spontaneous is characterized by postural headaches, pachymeningeal enhancement, venous sinus engorgement, enlarged pituitary gland. In some cases, can occur. Neurologic deterioration due to may occur if not treated promptly Methods: A 48 year old...
Objective: We report a rare case of recurrent strokes in giant cell arteritis (GCA) refractory to high dose steroid treatment. Background: Stroke is complication arteritis. Treatment guidelines recommend steroids and monitoring sedimentation rate (ESR) C-reactive protein (CRP), which may not be sufficient when stroke complication. Some studies have shown an increase mortality occurs GCA. To date, there insufficient data regarding the management prevention GCA. Design/Methods: A 78 year-old...
