High-resolution vessel wall imaging (HR-VWI) is a powerful tool in diagnosing intracranial vasculopathies not detected on routine imaging. We hypothesized that 7T HR-VWI may detect the presence of atherosclerotic plaques patients with atherosclerosis disease initially misdiagnosed as cryptogenic strokes.

The National Institutes of Health Stroke Scale (NIHSS) is the standard for assessing neurological deficits in acute ischemic stroke patients undergoing thrombectomy. However, data on NIHSS scores thrombectomy at national-level studies United States are lacking. Acute admitted between 2018 and 2021 were identified using ICD-10-CM codes from Nationwide In-patient Sample, with categorized into specific strata (0-9, 10-19, 20-29, 30-42). We analyzed effect in-hospital mortality, routine...

Data regarding health-related quality of life in breast cancer patients the Middle East are limited with fatigue and sleep disturbance being most distressing symptoms reported by treated for early cancer.The aim this study was to examine prevalence incidence insomnia among early-stage chemotherapy.This a prospective cohort study. We enrolled stage I-III chemotherapy at American University Beirut Medical Center. At three different time points (prior to, during, following chemotherapy), we...

<h3>BACKGROUND AND PURPOSE:</h3> High-resolution MR imaging allows the identification of culprit symptomatic plaques after administration gadolinium. Current high-resolution methods are limited by 2D multiplanar views and manual sampling ROIs. We analyzed a new 3D method to objectively quantify gadolinium plaque enhancement. <h3>MATERIALS METHODS:</h3> Patients with stroke due intracranial atherosclerotic disease underwent 7T imaging. segmentations its parent vessel were generated. Signal...

Background Current imaging modalities underestimate the severity of intracranial atherosclerotic disease (ICAD). High resolution vessel wall (HR-VWI) MRI is a powerful tool in characterizing plaques. We aim to show that HR-VWI more accurate at detecting and plaques compared digital subtraction angiography (DSA), time-of-flight (TOF) MRA, computed tomography angiogram (CTA). Methods Patients with symptomatic ICAD prospectively underwent 7T HR-VWI. calculated: degree stenosis, plaque burden...

Objective The association between allergy and multiple sclerosis (MS) is still unclear. In our study, we assessed the a self-reported history of allergic conditions with MS clinical MRI disease activity. Methods A subset 1349 patients enrolled in Comprehensive Longitudinal Investigation Multiple Sclerosis at Brigham Women’s Hospital (CLIMB) study completed self-administered questionnaire on environmental, food drug allergies. Patients were distributed among four groups: (1) (2) food, (3)...

Abstract BACKGROUND Hemorrhage is one of the most feared complications following ventriculostomy placement. Current studies have assessed factors associated with increased risk ventriculostomy-related hemorrhage (VRH). However, clinical significance VRH has not been determined. OBJECTIVE To correlate quantitative volumetric measurements new neurological symptoms. METHODS A retrospective review our institutional database patients during last decade was performed. Patients’ demographics and...

Background: Patients with an obstructive subclavian artery (SA) may exhibit symptoms of vertebrobasilar insufficiency known as steal syndrome (SSS). Endovascular treatment stent assisted percutaneous transluminal angioplasty (SAPTA) demonstrates significantly lower percentage intraoperative and postoperative complications in comparison open surgery. There is a 1-5% risk distal intracranial embolization through the ipsilateral vertebral (VA) during SAPTA. Objective: To assess safety...

Abstract Endovascular intervention has become the mainstay of treatment for subclavian artery stenosis in many centers, with high technical success and low complication rates. 1 , 2 However, potential embolization during proximal can lead to catastrophic posterior circulation ischemic complications.3–5 - 5 Although considered a rare complication, presence contralateral hypoplastic vertebral persisting anterograde blood flow on affected side is likely increase risk embolization. 3 The use...

Background: Hospitals with higher procedure volume are more likely to have lower rates of death or disability, most neurovascular surgical and endovascular procedures. The mechanical thrombectomy (MT) performed at hospitals is used as one the criteria for advanced-level designation stroke care. Objective: To determine relationship between MT in-hospital outcomes in acute ischemic patients United States. Methods: We analyzed nationally representative data from Nationwide Inpatient Sample...

To determine the effect of endovascular treatment (EVT) cerebral vasospasm on functional outcomes among poor-grade subarachnoid hemorrhage (SAH) patients.

To determine the relationship between procedure volume for MT and in-hospital outcomes in acute ischemic stroke patients United States.

Introduction The annual incidence of acute ischemic strokes or transient attacks due to chronic carotid occlusion (CCO) is estimated at 5‐10%. While initial trials did not show a clear benefit for surgical treatment symptomatic CCO, emerging data suggests that endovascular (EVT) may offer significant advantages over best medical management (BMM) in selected cases. However, the use EVT bilateral CCO has been previously investigated. Method We present case 67‐year‐old male with history...

Background Vertebrobasilar insufficiency can be caused by various pathologic conditions including atherosclerosis, dissections, steal phenomenon, etc. While endovascular treatment of those is well‐established, stenting vertebral artery (VA) compression stenosis due to cervical facet hypertrophy uncommon. We describe a case VA address the symptomatic mass effect from hypertrophy. Method A 78‐year‐old male with history deep venous thrombosis and paroxysmal atrial fibrillation presented several...

Introduction Epidural blood patch (EBP) remains the therapy of choice in treating refractory headaches due to low cerebrospinal fluid (CSF) pressure. If a CSF leakage source is detected, targeted fluoroscopy‐guided EBP should be considered over non‐targeted (blind) technique. Cervical can challenging treat with given high‐risk site. Methods We present case microcatheter‐guided cervical EBP. A 44‐year‐old male no significant past medical history presented 4 weeks upon sitting and standing up....

Introduction Cangrelor is an intravenous (IV), direct‐acting, and reversible P2Y12 inhibitor with rapid onset offset. Hence, use of in cerebrovascular interventions has recently expanded. We report our experience IV patients intracranial hemorrhage who required antiplatelet medication to avoid stent thrombosis. Methods reviewed the available computed tomographic (CT) images before, during, after completion infusion identify any increase hemorrhage. also ascertained neurological deterioration...

Background and Purpose: Although intra-arterial thrombolysis (IAT) is widely used as adjunct with mechanical thrombectomy in acute ischemic stroke patients, the patients who are likely to benefit not known. We analyzed real world data identify IA thrombectomy. Methods: Acute underwent IAT tissue plasminogen activator (tPA)/urokinase Trevo Retriever multicenter registry were analyzed. Primary endpoint was functional independence at 90 days post defined by a modified Rankin scale (mRS) of 0-2....

Background and Purpose: The role of surgical evacuation using craniotomy or endoscopic procedure in patients with intracerebral hemorrhage (ICH) associated oral anticoagulants is not well described. We investigated the 6-month functional outcomes ICH after hematoma either procedures. Methods: analyzed data consecutive who underwent compared between to those spontaneous ICH. also results treated performed multivariate analyses assess effect on modified Rankin Scale (mRS) at 6 months, which...
