Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence data supporting its use, rescue therapy (balloon angioplasty stent implantation) is often utilized such cases. Studies to large vessel occlusions, while outcomes and complications medium/distal occlusions (MDVOs) have not been...
Purpose To evaluate the safety and efficacy of stent-assisted embolization ruptured wide-necked intracranial aneurysms during acute subarachnoid hemorrhage (SAH). Materials Methods Institutional review board approval for this retrospective study was obtained; need to obtain informed consent waived. Results in 61 consecutive patients (20 men, 41 women; mean age, 55.1 years; range, 26–83 years) with acutely who were treated coil evaluated. The length angiographic follow-up 12.1 months (range,...
<h3>BACKGROUND AND PURPOSE:</h3> Flow diverters with antithrombotic coatings are increasingly used to improve the safety of flow diverter treatments intracranial aneurysms. This study aimed investigate and short-term efficacy new FRED X diverter. <h3>MATERIALS METHODS:</h3> Medical charts procedural imaging data a consecutive series patients aneurysms who were treated at 9 international neurovascular centers retrospectively analyzed. <h3>RESULTS:</h3> One hundred sixty-one (77.6% women; mean...
Intrasaccular devices have broadened treatment options for wide necked aneurysms. This study presents the preliminary experience with Artisse 2.0 device. Innovative NeurovaScular Product SurveIllance REgistry (INSPIRE) is a non-randomized, multicenter, real world clinical arms aneurysms (INSPIRE-A) and acute ischemic stroke (INSPIRE-S). interim analysis included 87 patients enrolled from November 2022 to April 2024 in INSPIRE-A cohort across 16 Europoean centers. Procedures followed standard...
Vessel perforation during thrombectomy is a severe complication and hypothesized to be more frequent medium vessel occlusion (MeVO) thrombectomy. The aim of this study was compare the incidence outcome patients with MeVO large (LVO) report on procedural steps that led perforation.
Background Flow diversion is an innovative and increasingly used technique for the treatment of intracranial aneurysms. New flow diverters (FDs) are being introduced to improve safety efficacy this treatment. The aim study was assess safety, feasibility, new Pipeline Vantage (PV) FD. Methods Patients with aneurysms treated PV at 10 international neurovascular centers were retrospectively analyzed. Patient aneurysm characteristics, procedural parameters, complications, grade occlusion...
<h3>BACKGROUND AND PURPOSE:</h3> The optimal antiplatelet regimen after flow diverter treatment of cerebral aneurysms is still a matter debate. A single therapy might be advantageous in determined clinical scenarios. This study evaluated the efficacy and safety prasugrel versus aspirin clopidogrel dual therapy. <h3>MATERIALS METHODS:</h3> We performed post hoc analysis 4 retrospective multicenter studies including ruptured unruptured treated with diversion using either or Primary end points...
Flow diverters are sometimes used in the setting of acutely ruptured aneurysms. However, thromboembolic and hemorrhagic complications feared evidence regarding safety is limited. Therefore, this multicenter study we evaluated complications, clinical, angiographic outcomes patients treated with a flow diverter for aneurysms.We conducted retrospective observational 44 consecutive who underwent treatment within 15 days after rupture an intracranial aneurysm at six centers. The primary end point...
Background Intrasaccular devices are increasingly used in endovascular therapy of intracranial aneurysms, particular wide-necked and ruptured aneurysms. The Trenza Embolization Device (TED) is an innovative intrasaccular device for medium- to large-sized Currently, literature about the TED scarce. Methods In eight participating European centers, 25 aneurysms (3 ruptured) patients (18 females, mean age 62.4 years) treated with outside currently recruiting prospective, post-market, multicenter...
Background: There are limited therapy options in case of failed reperfusion after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence data supporting its use, rescue angioplasty (RA; with or without stent implantation) is often utilized such cases. Studies to large vessel occlusions, while outcomes and complications RA medium/distal occlusions (MDVOs) have not been reported. This study aims report MDVO stroke patients. Methods:...
Background/purpose Gender bias in academic medicine has been widely described. In Europe, training and career pathways neurointervention (NI) are heterogeneous. We hypothesize that the access route to neuroradiology specialty NI subspecialty may correlate with proportion of women field their progression. Methods An online survey consisting 18 questions was distributed through European professional societies several social platforms. A total 422 responses from 54 different countries were...
<title>Abstract</title> <bold>Purpose:</bold> Treating small-caliber vessel aneurysms with flow diverters presents challenges due to narrow luminal diameters and tortuous vasculature, which make navigation deployment of conventional devices using standard microcatheters more difficult. The Silk Vista Baby (SVB, Balt, Montmorency, France) diverter was developed treat intracranial located in smaller vessels or distal lesions is compatible 0.017″ microcatheters. We present the largest...
Blood blister-like aneurysms (BBAs) are among the most hazardous cerebrovascular to treat; microsurgical treatment of these small, wide-necked, and exceptionally fragile place patients at significant risk morbidity or mortality. We report two cases ruptured BBAs attempted be treated for first time with stent-assisted coil embolization solely review current literature on options. Our underwent in acute stage subarachnoid hemorrhage (SAH). One patient was successfully without procedure-related...
Wide necked bifurcation aneurysms (WNBA) are among the most difficult to treat. Very low dome-to-neck (DTN) and aspect ratios provide an even greater challenge in management of WNBAs. We present safety efficacy profile for endovascular clip system (eCLIPs) device treatment this subset WNBAs with very unfavorable morphologies.In our case series, 24 patients treated at 12 international centers were taken from a larger prospective voluntary post-marketing registry 65 eCLIPs coiling. Those who...
<h3>BACKGROUND AND PURPOSE:</h3> Randomized trials in the late window have demonstrated efficacy and safety of endovascular thrombectomy large-vessel occlusions. Patients with M2-segment MCA occlusions were excluded from these trials. We compared outcomes patients M2-versus-M1 presenting 6–24 hours after symptom onset. <h3>MATERIALS METHODS:</h3> Analyses on pooled data studies enrolling stroke treated 90-day functional independence (mRS ≤ 2), mortality, symptomatic intracranial hemorrhage,...
Intrasaccular flow disruption is an endovascular approach for the treatment of wide-neck aneurysms and, more specifically, bifurcation aneurysms, which are challenging to treat with previously developed technologies. The Woven EndoBridge (WEB) device has demonstrated its efficacy and safety, both unruptured ruptured aneurysms.
Purpose: To evaluate the long‐term results of endovascular sclerotherapy in treating venous extremity malformations and to assess quality life after treatment. Material Methods: Twenty‐four patients were included who had completed treatment with ethanol a minimum one year observation period. Nineteen attended clinical control. treatment, 23 filled questionnaire which 20 multiple‐choice questions exploring four dimensions: psychological, physical social functioning, pain.
