The mechanisms and outcomes in coronavirus disease (COVID-19)-associated stroke are unique from those of non-COVID-19 stroke.To describe the efficacy acute revascularization large vessel occlusion (LVO) setting COVID-19 an international cohort.We conducted multicenter retrospective study consecutively admitted patients with concomitant LVO across 50 comprehensive centers. Our control group constituted historical controls presenting receiving a mechanical thrombectomy between January 2018...
Introduction: Mechanical thrombectomy (MT) devices were fundamentally designed for the treatment of cardioembolic (CE) strokes despite that 10-20% large vessel occlusions (LVO) are caused by artery atherosclerosis (LAA), which may not respond comparably. Therefore, differentiation between LAA and non-LAA LVO be critical selecting ideal MT technique. Here, we construct an algorithm use in emergent setting pre-operatively to differentiate using clinical radiographic features. Methods: Using...
The goal of this study was to compare the freehand technique catheter placement using external landmarks with Ghajar Guide for procedure. a ventricular can be lifesaving procedure, and it is commonly performed by all neurosurgeons. Various methods have been described cannulate system, including modified Friedman tunnel in which soft polymeric tube inserted through burr hole. Paramore, et al., noted that two thirds noninfectious complications related incorrect positioning catheter.Forty-nine...
The authors report their results in a series of large or giant carotid ophthalmic segment aneurysms clipped using retrograde suction decompression.A retrospective review clinical data and treatment summaries was performed for 18 patients with artery managed operatively via decompression. Visual outcomes, Glasgow Outcome Scale (GOS) scores, operative complications were determined. Postoperative angiography assessed.During 17-year period, underwent surgery mean aneurysm size 26 mm. Three...
Object. The authors report on important factors that influenced clinical and angiographically demonstrated outcomes in patients treated using coil embolization. Methods. This study included 160 consecutive who underwent endovascular embolization for treatment of intracranial aneurysms. Univariate multivariate logistic regression analyses were performed to assess the immediate posttreatment angiographic result. Cox analysis was used establish related occurrence negative events as well a curve...
Treatment of patients with cerebral large vessel occlusion thrombectomy and tissue plasminogen activator (tPA) leads to incomplete reperfusion. Using rat models embolic transient middle artery (eMCAO tMCAO), we investigated the effect on stroke outcomes small extracellular vesicles (sEVs) derived from endothelial cells (CEC-sEVs) in combination tPA (CEC-sEVs/tPA) as a treatment eMCAO tMCAO rat. The sEVs clots acquired who had undergone mechanical healthy human CEC permeability was also...
To evaluate the effects of preoperative embolization on overall surgical outcomes after meningioma resection and determine whether pre- postembolization tumor enhancement patterns magnetic resonance imaging (MRI) scans can be used to assess efficacy embolization. We developed a prospective database all patients who underwent with or without for extra-axial intracranial meningiomas from 2004 2010. Using specialized computer software, total volume was calculated in MRI quantify percentage...
Previous studies suggest that mechanisms and outcomes in patients with COVID-19-associated stroke differ from those non-COVID-19-associated strokes, but there is limited comparative evidence focusing on these populations. The aim of this study, therefore, was to determine if a significant association exists between COVID-19 status revascularization functional following thrombectomy for large vessel occlusion (LVO), after adjustment potential confounding factors.A cross-sectional,...

OBJECT Treatment of brain arteriovenous malformations (bAVMs) in the elderly remains a challenge for cerebrovascular surgeons. In this study authors reviewed patient characteristics, treatments, angiographic results, and clinical outcomes 28 patients over 65 years age who were treated at Henry Ford Hospital between 1990 2014. METHODS The bAVM database authors' institution was queried records with bAVMs, data regarding demographics, presenting symptoms, angioarchitecture, treatment...
Object The authors reviewed their experience in 7 cases of nonacute intracranial occlusions and near which the patients underwent angioplasty stent implantation for direct cerebral revascularization. Methods Between 2005 2008, 4 men 3 women revascularization intracerebral or occlusions. Five had chronic angiographically documented occlusion 2 locations treated vessels included supraclinoid internal carotid arteries, middle 1 vertebral artery. Prior to intervention, all were symptomatic...
Distal fusiform aneurysms of the superior cerebellar artery (SCA) are rare and present several challenges to clinicians, especially when ruptured. While treatment options available, including surgical clipping endovascular coiling, numerous still remain due presence vital neighboring neurovascular structures. In addition, complications that arise compromise brainstem perforators make these difficult treat. This case report demonstrates successful a ruptured aneurysm SCA with flow-diverting...

Distinct origins of the external carotid artery and internal (ICA) from aortic arch have been rarely described, represent an aberrant development arches during fetal life. This anatomical variation is usually discovered incidentally; infrequently, aneurysm cervical ICA might accompany this rare configuration. We describe one such case in a patient with Noonan syndrome who presented pulsatile neck mass. The diagnostic features management review literature are presented.
ABSTRACT: Background and purpose: Cervical internal carotid artery (ICA) occlusion associated with middle cerebral (MCA) embolic requires prompt revascularization to prevent devastating stroke. With the advent of endovascular techniques for chemical mechanical thrombolysis, clinical outcome patients major arterial occlusions will improve. Finding most expedient pathway site end organ thrombolysis is important. Methods: We present two cases acute stroke secondary thrombotic cervical ICA MCA...
The treatment of a rare, nontraumatic, fusiform aneurysm the anterior temporal artery (ATA) via endovascular techniques is presented, and procedural nuances are highlighted.We performed retrospective chart review collected demographic clinical data on patient presented here; details were extracted from operative notes.Following successful balloon test occlusion (BTO) ATA, complete coil embolization its associated was performed. Postprocedurally, did not suffer any adverse neurological...
