Recent case-series of small size implied a pathophysiological association between coronavirus disease 2019 (COVID-19) and severe large-vessel acute ischemic stroke. Given that strokes are typically associated with poor prognosis can be very efficiently treated recanalization techniques, confirmation this putative is urgently warranted in large representative patient cohort to alert stroke clinicians, inform pre- in-hospital pathways. We pooled all consecutive patients hospitalized...
Background and Purpose— Radial artery catheterization is an alternate route of access that has started to gain more widespread use for neuroendovascular procedures, there have been few studies describe its safety efficacy. We present our institution’s experience in performing interventions via a transradial approach, with excellent clinical outcomes patient satisfaction measures. Methods— conducted retrospective analysis identified 223 patients who underwent 233 consecutive radial at...
Robots in surgery aid performing delicate, precise maneuvers that humans, with inherent physical abilities, may be limited to perform. The CorPath 200 system is FDA approved and being implemented the US for interventional cardiology procedures. GRX robotic-assisted platform next-generation successor of 200.To discuss feasibility early experience use neuroendovascular procedures, including transradial diagnostic cerebral angiograms carotid artery stenting.The cases 10 consecutive patients who...
Background Currently, there are no large-scale studies in the neurointerventional literature comparing safety between transradial (TRA) and transfemoral (TFA) approaches for flow diversion procedures. This study aims to assess complication rates a large multicenter registry TRA versus TFA diversion. Methods We retrospectively analyzed cases cerebral aneurysms from 14 institutions 2010 2019. Pooled analysis of proportions was calculated using weighted with 95% CI account results multiple...
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: First pass effect (FPE), achievement of complete recanalization (mTICI 2c/3) with a single pass, is significant predictor favorable outcomes for endovascular treatment (EVT) in large vessel occlusion stroke (LVO). However, data concerning the impact on functional and predictors FPE medium occlusions (MeVO) are scarce. Patients Methods: We conducted an international retrospective study MeVO cases. Multivariable logistic modeling was used to establish independent FPE. Clinical...
Background Wide-necked bifurcation aneurysms (WNBAs) present unique challenges for endovascular treatment. The Woven EndoBridge (WEB) device is an intrasaccular braided device, recently approved by the FDA treatment of WNBAs. While intracranial with WEB has been shown to yield adequate occlusion rate 85% at 1 year, few data have published patients ruptured aneurysms. Objective To a multi-institutional series depicting safety and efficacy using as primary modality in Methods A retrospective...
The transradial approach (TRA) has gained increasing popularity for neuroendovascular procedures. However, the experience with TRA in neuroangiography is still early stages most centers, and safety feasibility of this have not been well established. purpose study to report procedures.We reviewed charts from six institutions USA include consecutive patients who underwent diagnostic or interventional procedures through July 2018 2019. Collected data included baseline characteristics,...
BACKGROUND: The Woven EndoBridge (WEB) device (Terumno Corp. [parent company of Microvention]) was approved by the U.S. Food and Drug Administration as first intrasaccular for intracranial aneurysm treatment in December 2018. Its use has become more common since then, but both trial results postmarket experiences have raised questions about efficacy achieving complete obliteration. Retreatment after WEB embolization not been extensively discussed. OBJECTIVE: To discuss incidence retreatment...
Background For acute proximal intracranial artery occlusions, contact aspiration may be more effective than stent‐retriever for first‐line reperfusion therapy. Due to the lack of data regarding medium vessel occlusion thrombectomy, we evaluated outcomes according technique in a large, multicenter registry. Methods Imaging, procedural, and clinical patients with occlusions (M2, A1, or P1) distal (M3, A2, P2, further) treated at 37 sites 10 countries were analyzed endovascular (stent‐retriever...
OBJECTIVE By providing a more physiological approach to the treatment of intracranial aneurysms, Pipeline embolization device (PED) has revolutionized endovascular aneurysms. Although there are many flow diverters on market, authors report their experience with PED, first diverter be approved by Food and Drug Administration. They aimed assess efficacy safety PED diversion for wide range as well look at factors affecting occlusion. METHODS This is retrospective study prospectively maintained...
Background: Efficient management of acute ischemic stroke is critical to reducing disability and mortality. The hub-and-spoke telestroke model has been developed extend specialized care regions with limited resources, ensuring timely diagnosis treatment. Objective: To evaluate the effectiveness a large-scale network in delivering care, focusing on rates thrombolysis mechanical thrombectomy, treatment timelines, patient outcomes. Methods: We conducted retrospective analysis 9,702 patients...
Abstract BACKGROUND A dramatic improvement in obliteration rates of large, wide-necked aneurysms has been observed after the FDA approved Pipeline Embolization Device (PED) 2011. OBJECTIVE To assess predictors complications, morbidity, and unfavorable outcomes a large cohort patients with treated PED. METHODS retrospective chart review prospectively maintained database for subjects flow diversion from 2010 to 2019. RESULTS total 598 were during period extending 2019 (84.28% females, mean age...
Background In response to the COVID-19 pandemic, many centers altered stroke triage protocols for protection of their providers. However, effect workflow changes on patients receiving mechanical thrombectomy (MT) has not been systematically studied. Methods A prospective international study was launched at initiation pandemic. All included participated in Stroke Thrombectomy and Aneurysm Registry (STAR) Endovascular Neurosurgery Research Group (ENRG). Data collected during peak months surge...
Background The Woven EndoBridge (WEB) device is approved in the USA for treatment of unruptured wide-neck bifurcation aneurysms. However, safety and effectiveness WEB ruptured intracranial aneurysms not clear. We aim to evaluate perioperative patients with Methods This retrospective study, conducted at eight centers USA, included treated setting subarachnoid hemorrhage (SAH). Safety outcomes intraoperative complications such as vessel perforation, thromboembolic events, postoperative...
