Objective Flexible large lumen aspiration catheters and stent retrievers have recently become available in the USA for revascularization of vessel occlusions presenting within context acute ischemic stroke (AIS). We describe a multicenter experience using combined retrieval technique thrombectomy. Design A retrospective analysis to identify patients receiving manual treatment AIS between August 2012 April 2013 at six high volume centers was conducted. Outcome variables, including...
BACKGROUND: Stent-assisted coiling with 2 stents in a Y configuration is technique for complex wide-neck bifurcation aneurysms. OBJECTIVE: We sought to provide long-term clinical and angiographic outcomes Y-stent coiling, which are not currently established. METHODS: Seven centers provided deidentified, retrospective data on all consecutive patients who underwent stent-assisted an intracranial aneurysm configuration. RESULTS: Forty-five treatment by coiling. Their mean age was 57.9 years....
Introduction The direct aspiration first pass technique (ADAPT) has been introduced as a simple and fast method for achieving good angiographic clinical outcomes using large bore catheters the treatment of acute ischemic stroke (AIS). We present single center's long term experience with ADAPT. Methods Retrospective analysis database was gathered on patients undergoing thrombectomy ADAPT at center. Specific parameters captured included age, gender, National Institutes Health Stroke Scale...
Emergent carotid artery stenting plus mechanical thrombectomy is an effective treatment for acute ischemic stroke patients with tandem occlusion of the anterior circulation. However, there limited data supporting safety this approach in treated prior intravenous thrombolysis (IVT). We aimed to investigate emergent stenting-mechanical patient population IVT—We assessed because atherosclerotic that were from multicenter observational Thrombectomy Tandem Lesions registry. Patients divided into...
The treatment of acute ischemic stroke is traditionally centered on time criteria, although recent evidence suggests that physiologic neuroimaging may be useful. In a multicenter study we evaluated the use CT perfusion, regardless from symptom onset, in patients selected for intra-arterial stroke.Three medical centers retrospectively assessed with National Institute Health Stroke Scale ≥ 8, onset. perfusion maps were qualitatively assessed. Patients defined salvageable penumbra underwent...
The endovascular stent-assisted coiling approach for the treatment of cerebral aneurysms is evolving rapidly with availability new stent devices. It remains unknown how each type affects safety and efficacy stent-coiling procedure.This study compared outcomes using Neuroform (NEU), Enterprise (EP), Low-profile Visualized Intraluminal Support (LVIS) stents. Patient characteristics, details angiographic results Raymond-Roy grade scale (RRGS), procedural complications were analyzed in our...
Abstract BACKGROUND Aneurysm recurrence after coiling has been associated with aneurysm growth, (re)hemorrhage, and a greater need for follow-up. The second-generation HydroCoil Embolic System (HES; MicroVention, Inc) consists of platinum core integrated hydrogel was developed to reduce through enhancing packing density healing within the aneurysm. OBJECTIVE To compare between HES bare coil (BPC) in new-generation Hydrogel Endovascular Treatment Trial (HEAT). METHODS HEAT is randomized,...
Traditional treatment in acute ischemic stroke is based on time criteria when administering intravenous and intra-arterial therapies. However, recent evidence suggests that image-based may be useful for selecting patients interventions. The use of CT perfusion (CTP)-based criteria, regardless from symptom onset, patient selection was assessed.Patients with who presented to the emergency department at Medical University South Carolina a National Institute Health Stroke Scale score ≥ 8, were...
This study retrospectively compared the clinical and angiographic outcomes of treating cerebral aneurysms with Neuroform (NEU), Enterprise (EP), Low-profile Visualized Intraluminal Support (LVIS/LVIS Jr) stents.We conducted a retrospective analysis procedural database. All aneurysm procedures using any three types self-expanding nitinol stents (NEU, EP LVIS/LVIS were included. Intra-procedure complications, post-procedure results (Raymond-Roy grade scale, RRGS) analyzed retrospectively. A...
Background The effect of the five positive randomized controlled trials on thrombectomy practices and procedural volume has yet to be defined. Further, few studies have attempted define modern in terms selection criteria devices used. Methods A 21 question survey Society Neurointerventional Surgery (SNIS) physicians was administered using SurveyMonkey website, addressing current as well changes from before January 1, 2015 months after this date. Results total 78 responses were obtained...
Clot density (Hounsfield units, HU) and perviousness (post-contrast increase in the HU of clot) are thought to be associated with clot composition. We evaluate whether these imaging characteristics were angiographic outcomes aspiration stent retriever thrombectomy COMPASS: a trial versus as first-line approach for large vessel occlusion.Clot measured by two independent operators who blind all final clinical outcomes. The association Thrombolysis In Cerebral Infarction (TICI) scale after...
Socioeconomic status influences health outcomes, including cerebrovascular diseases. Patients from socioeconomically deprived areas may present with more severe conditions due to delayed access care. This study evaluates the association between neighborhood-level deprivation, measured by Area Deprivation Index (ADI), and treatment of ruptured intracranial aneurysms (RIAs) compared unruptured (UIAs) across multiple centers. retrospective cohort analyzed data 4517 patients treated for cerebral...
