The main concern with the use of pipeline embolization device (PED) in treating cerebral aneurysms is risk hemorrhagic and thromboembolic complications.To investigate if P2Y12 reaction unit (PRU) values are associated complications after treatment PED to find an optimal range preprocedural PRU values.Two hundred thirty-one patients 248 treated were retrospectively identified. Patients started on dual-antiplatelet at least 10 days before intervention. checked. Univariate multivariate logistic...
Background and Purpose— Several endovascular treatment options are available for cavernous carotid aneurysms. We compared pipeline embolization device (PED) versus conventional in terms of evolution mass effect, complications, recurrence, retreatment rate. Methods— One hundred fifty-seven patients harboring 167 aneurysms were treated using PED placement, coiling, stent-assisted vessel destruction. Procedural angiographic results, clinical outcomes analyzed compared. Results— There no...
OBJECTIVE With the increasing number of aneurysms treated with endovascular coiling, more recurrences are being encountered. The aim this study was to evaluate efficacy and safety microsurgical clipping in treatment recurrent, previously coiled cerebral identify risk factors that can affect outcomes procedure. METHODS One hundred eleven patients recurrent whose lesions were managed by surgical between January 2002 October 2014 identified. rates aneurysm occlusion, retreatment, complications,...
INTRODUCTION: Blister aneurysms (BAs) of the supraclinoid internal carotid artery (ICA) pose unique treatment challenges due to their broad neck, friable adventitial walls, complex angioarchitecture and heterogeneity. There is a paucity data on long-term outcomes microsurgical bypass with clipping or trapping, endovascular flow diversion (FD). METHODS: Data all BAs treated by either clip-trapping FD between 2005-2024 was retrospectively reviewed. Outcomes complications were assessed in...
The Pipeline Embolization Device is a widely utilized flow diverter in the treatment of intracranial aneurysms.To assess incidence, clinical significance, predictors, and outcomes in-Pipeline stenosis (IPS).Angiographic studies 139 patients treated between 2011 2013 were independently reviewed by 2 authors for presence IPS. Multivariable logistic regression analysis was conducted to determine predictors IPS.A total 21 (15.8%) demonstrated some degree IPS during follow-up period at mean time...
The use of flow-diversion to treat ophthalmic segment aneurysms (OSA) has not been well evaluated.To assess the visual outcomes, obliteration rate, and need for retreatment OSA treated by pipeline embolization device (PED).Patients who underwent treatment with PED from 2009 2014 were selected retrospectively reviewed. Patient's age, sex, mode presentation, aneurysm size recorded. complication rates, (due recurrence or worsening symptoms), occlusion evolution symptoms, headache/retro-orbital...
Transradial access is increasingly used among neurointerventionalists as an alternative to the transfemoral route. Currently available data, building on interventional cardiology experience, primarily focus right radial access. However, there are clinical scenarios when left-sided may be indicated. The purpose of this study was evaluate technical feasibility left transradial cerebral angiography across three institutions.A retrospective chart review performed for patients who underwent...
Flow diversion is typically reserved for large, giant, or morphologically complex aneurysms. Coiling remains a first-line treatment small, simple aneurysms.To compare coiling and flow in uncomplicated intracranial aneurysms (typically amenable to coiling).Forty patients treated with the pipeline embolization device (PED) small (<10 mm), that would have also been were identified. These matched 1:1 fashion 40 comparable coiling. Matching was based on age, gender, aneurysm size, morphology.The...
OBJECTIVE Cerebral vasospasm (cVSP) is a frequent complication of aneurysmal subarachnoid hemorrhage (aSAH), with significant impact on outcome. Beta blockers (BBs) may blunt the sympathetic effect and catecholamine surge associated ruptured cerebral aneurysms prevent cardiac dysfunction. The purpose this study was to investigate association between preadmission BB therapy cVSP, dysfunction, in-hospital mortality following aSAH. METHODS This retrospective cohort patients aSAH who were...
The optimal duration for dual antiplatelet therapy (DAPT) after stent-assisted coiling (SAC) of intracranial aneurysms is unclear. Longer-term may reduce thrombotic complications but increase the risk bleeding complications.
Most intracranial stents contain nickel alloy, and allergy or hypersensitivity is common. Neurological injury following endovascular treatment with a containing stent has been reported in patients purported allergy, but it unclear whether these reactions represent true hypersensitivity. We quantified release from commonly used to investigate such should be avoided allergy.We examined seven stents: Enterprise, LVIS Jr, Neuroform, Wingspan, Zilver, Pipeline Flex Embolization Device, Surpass...
Introduction Endovascular embolization of intracranial meningiomas is commonly used as an adjunct to surgical resection. We sought describe the anatomic locations and vascular supplies identify characteristics predictive successful preoperative endovascular embolization. Methods conducted a retrospective review 139 meningioma cases receiving cerebral angiograms for possible at our institution between December 2000 March 2017. The extent embolization, arterial supply, location, procedural...
OBJECTIVE The authors sought to determine the predictors of late neurological and hospital-acquired medical complications (HACs) in patients with low-grade aneurysmal subarachnoid hemorrhage (aSAH). METHODS conducted a retrospective study 424 aSAH admitted their institution from 2008 2015. Data collected included patient comorbidities, Hunt Hess (HH) grade, ICU length stay (LOS), complications. A logistic regression analysis was performed for hospital-associated RESULTS Out patients, 50...
The advent of mechanical thrombectomy (MT) has become an effective option for the treatment acute ischemic stroke in addition to tissue plasminogen activator (tPA). With recent advances device technology, MT significantly altered hospital course and functional outcomes patients. authors' goal was establish most up-to-date reperfusion with evolution technology.
