Introduction: Although stentrievers (SRs) are widely used for mechanical thrombectomy (MT), the impact of device dimensions on optimizing reperfusion outcomes in high clot burden cases is unclear. Our study aimed to investigate the effect of SR size on angiographic and clinical outcomes in patients with acute terminal internal cerebral artery (TICA) occlusion.

Methods: We analyzed ROSSETTI registry data to compare technical and clinical outcomes of TICA occlusion patients treated with MT without rescue therapy, according to SR diameter and length: 6 × 41-50 mm, 6 × 20-40 mm, and <6 × 20-50 mm.

Although stentrievers (SRs) have been a mainstay of mechanical thrombectomy (MT), and current guidelines recommend the use of SRs in the treatment of large vessel occlusion stroke (LVO), there is a paucity of studies in the literature comparing SRs directly against each other in terms of mechanical and functional properties. Timely access to endovascular therapy and the ability to restore intracranial flow in a safe, efficient, and efficacious manner have been critical to the success of MT. This study aimed to investigate the impact of contemporary SR characteristics, including model, brand, size, and length, on the first-pass effect (FPE) in patients with acute ischemic stroke.

Rationale: In-stent reocclusion after endovascular therapy has a negative impact on outcomes in acute ischemic stroke (AIS) due to tandem lesions (TL). Optimal antiplatelet therapy approach in these patients to avoid in-stent reocclusion is yet to be elucidated.

Aims: To assess efficacy and safety of intravenous tirofiban versus intravenous aspirin in patients undergoing MT plus carotid stenting in the setting of AIS due to TL.

Background: In-stent thrombosis after mechanical thrombectomy (MT) worsen outcomes in acute ischemic stroke (AIS) due to tandem lesions (TL). Although an optimal antiplatelet therapy is needed, the best approach to avoid in-stent thrombosis is yet to be elucidated.

Hypothesis: Low-dose intravenous tirofiban is superior to intravenous aspirin in avoiding in-stent thrombosis in patients undergoing MT plus carotid stenting in the setting of AIS due to TL.

Introduction: Intra- or peri-procedural aneurysm rupture is one of the most feared adverse effects associated with embolization. Our aim was to report the characteristics of patients suffering intra- or peri-procedural ruptures during embolization of cerebral aneurysms.

Patients And Methods: Between March 1994 and October 2021, 648 consecutive cerebral aneurysms were treated by endovascular procedure at our facility.

Introduction: Mechanical thrombectomy for large vessel occlusion in the anterior circulation has been shown to be beneficial. The question of whether this technique is safe and effective in the distal vasculature remains unanswered. We wanted to compare outcome data from mechanical thrombectomy of M2 branches of the middle cerebral artery (MCA) with those of the M1 segment, and better understand the clinical predictors of these M2 occlusions.

Background: The optimal endovascular treatment (EVT) technique for middle cerebral artery (MCA) M2 segment occlusions remains unknown. We aim to analyze whether reperfusion rate, procedure times, procedure-related complications, and clinical outcome differed between patients with isolated M2 occlusions who underwent stent-retriever (SR) alone versus combined SR and contact aspiration (CA) as a front-line EVT.

Methods: Patients who underwent EVT for isolated MCA-M2 occlusion were recruited from the prospectively ongoing ROSSETTI registry.

Background: Balloon guide catheter (BGC) in stent retriever based thrombectomy (BGC+SR) for patients with large vessel occlusion strokes (LVOS) improves outcomes. It is conceivable that the addition of a large bore distal access catheter (DAC) to BGC+SR leads to higher efficacy. We aimed to investigate whether the combined BGC+DAC+SR approach improves angiographic and clinical outcomes compared with BGC+SR alone for thrombectomy in anterior circulation LVOS.

Background: First-pass effect (FPE) has been established as a key metric for technical success and strongly correlates with better clinical outcomes. Most data supporting improved outcomes with the use of a balloon guide catheter (BGC) predate the advent of last-generation large-bore intracranial aspiration catheters. We aim to evaluate the impact of BGC in FPE and clinical outcomes in a large cohort of patients treated with contemporary technology.

Objectives: Imaging selected patients with proximal anterior circulation stroke who demonstrate limited infarct may benefit from endovascular treatment beyond conventional time limits. Our aim was to evaluate the results of the EVT group series arriving between 6 and 24 hours from the onset of symptoms with (ASPECTS) ≥7 to our hospital (with 24/7 interventional neuroradiology) comparing them with those obtained in our prospectively registered series arriving between 0 and 6 hours.

Materials And Methods: The inclusion criteria were ≥18 years, an interval between stroke and endovascular treatment of 6-24 hours, prestroke score mRS 0-2, no intracranial haemorrhage, (NIHSS) scale 8-22 and infarct evaluated by CT scan ≥7 in ASPECTS scale.

Purpose: The aim is to report the incidence and risk factors of contrast-induced nephropathy after the use of iodine-based contrast for the endovascular treatment of acute ischemic stroke.

Methods: Data from patients who underwent neuroendovascular procedures in a center over a period of 22 months were analysed retrospectively. Contrast-induced nephropathy was determined by an increase in serum creatinine level of >25% of baseline or an absolute increase in serum creatinine level of at least 44 µmol/L (0.

Introduction: Strokes in children are characterised by a high mortality rate while, at the same time, the low number of cases makes it difficult to gain practical experience. As heart disease is the most common risk factor, and as more and more cardiological interventions are being carried out, an increase in the incidence of paediatric stroke is expected. In some cases a transplant is required.

Background: A stent is often necessary for the treatment of stroke. In such cases,it is essential for the patient to have antiplatelet therapy. There are several methods of antiaggregation, such as oral loading doses of aspirin and clopidogrel, intravenous aspirin, or intravenous glycoprotein IIb/IIIa receptor antagonists, such as abciximab.

Background And Purpose: Surgery is known to have fewer adverse events in patients aged >75 years with carotid stenosis, but some are not candidates due to comorbidity. Stenting using protection devices is the most accepted endovascular technique. Our aim is to show the safety and efficacy of carotid stenting without any protection device in these patients.
