Background And Aims: Previous observational data indicate that young adults treated with intravenous thrombolysis (IVT) for acute ischemic stroke have more favorable outcomes and less complications when compared to older adults. Given the limited data on this topic, we aimed to provide more evidence on clinical outcomes and safety in such patients, using a large international thrombolysis registry.
Methods: In this prospective multicenter study, we used data from the Thrombolysis in Ischemic Stroke Patients (TRISP) registry from 1998 to 2020.
Background And Objectives: The benefit of mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS) with basilar artery occlusion (BAO) and a baseline National Institute of Health Stroke Scale (NIHSS) score <10 is unclear because this subpopulation has been substantially excluded from large clinical trials. The aim of our study was to determine whether MT ± IV thrombolysis (IVT) improves functional outcomes compared with IVT alone in patients with BAO and a NIHSS score <10.
Methods: We emulated a hypothetical trial including adult patients with BAO, a baseline NIHSS score <10, and prestroke modified Rankin scale (mRS) scores 0-2, comparing MT (±IVT) with IVT alone.
Introduction: Data on safety and efficacy of endovascular thrombectomy (EVT) for acute ischemic stroke in older patients are limited and controversial, and people aged 80 or older were under-represented in randomized trials. Our aim was to assess EVT effect for ischemic stroke patients aged ⩾80 at a nationwide level.
Patients And Methods: The cohort included stroke patients undergoing EVT from the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS).
Background: Acute intracranial occlusion of the internal carotid artery (ICA) can be distinguished into (a) occlusion of the terminal ICA, involving the proximal segments of the middle or anterior cerebral artery (ICA-L/-T) and (b) non-terminal intracranial occlusions of the ICA with patent circle of Willis (ICA-I). While patients with ICA-L/-T occlusion were included in all randomized controlled trials on endovascular therapy (EVT) in anterior large vessel occlusion, data on EVT in ICA-I occlusion is scarce. We thus aimed to evaluate effectiveness and safety of EVT in ICA-I occlusions in comparison to ICA-L/-T occlusions.

- The study evaluated the effectiveness and safety of endovascular thrombectomy (EVT) in acute ischemic stroke patients treated within early (<6 hours) and extended (6-24 hours) time windows after symptom onset.
- It compared outcomes like good functional recovery, intracranial hemorrhage, and mortality rates between the two groups, finding that while early treatment showed slightly better recovery rates, both time frames had similar safety outcomes.
- Overall, the findings suggest that EVT remains a viable option for patients up to 24 hours after stroke symptoms, aligning with real-world clinical practices.
Objective: The SeLECT 2.0 score is a prognostic model of epilepsy after ischemic stroke. We explored whether replacing the severity of stroke at admission with the severity of stroke after treatment at 72 h from onset could improve the predictive accuracy of the score.

- The study aimed to explore treatment strategies for tandem occlusions (TOs) during emergent carotid stenting in Italy, highlighting uncertainties in the best approach despite benefits from mechanical thrombectomy.
- A survey of 66 centers yielded a response rate of 84.8%, revealing that most prefer a retrograde approach with a closed-cell stent and single antiplatelet therapy during deployment.
- The findings indicate that practices for managing TOs are inconsistent across the Italian neurovascular community, emphasizing the need for more evidence to establish a standardized treatment protocol.
Background And Purpose: Mechanical thrombectomy (MT) along with emergent carotid stent placement (eCAS) has been suggested to have a greater benefit in patients with tandem lesions (TL), compared with other strategies of treatment. Nonetheless, there is no agreement on whether the intracranial occlusion should be treated before the cervical ICA lesion, or vice versa. In this retrospective multicenter study, we sought to compare clinical and procedural outcomes of the 2 different treatment approaches in patients with TL.

Instead, little is known about the effectiveness of MT in stroke patients with posterior tandem occlusion (p-TO). We aimed to compare MT within 24 h from last known well time in ischemic stroke patients with p-TO versus a-TO.

Methods: We conducted a cohort study on prospectively collected data from patients with M1 and/or M2 segment of middle cerebral artery occlusion with a thrombolysis in cerebral infarction 0-1 at the end of procedure. Primary outcome was 90-day poor outcome.
Background: Endovascular treatment (EVT) is the standard of care of ischaemic stroke due to occlusion of large vessels. Although EVT can significantly improve short- and long-term outcomes, functional dependence can persist despite the achievement of a successful recanalization. The evidence about the predictors of post-stroke epilepsy (PSE) in patients with stroke treated by EVT is limited.
View Article and Find Full Text PDFBackground: Hemiballism (HB) and hemichorea (HC) are the most frequent secondary movement disorders, usually caused by cerebrovascular diseases. In only a minority of cases, these involuntary movements are not self-limited, and they may severely compromise patients' quality of life, so that symptomatic treatments are required. Typical and atypical neuroleptics as well as tetrabenazine are considered therapies of choice.

- Fabry disease (FD) is a rare genetic disorder linked to strokes, and there's ongoing debate about when to test for it in stroke patients.
- This study, part of the Fabry-Stroke Italian Registry, screened nearly 1,906 stroke patients for FD by checking alpha-galactosidase A activity and conducting genetic tests, identifying a small number of affected individuals.
- The findings suggest that limiting FD screening only to cryptogenic strokes could miss a significant number of cases, highlighting the importance of recognizing clinical signs that may indicate the need for testing.
Central nervous system vasculitis (CNSV) is an uncommon and poorly understood form of vasculitis. Early recognition is important because medical treatment might improve the outcome. However, randomized clinical trials on CNSV treatment do not exist.

- This study looked at how patients with a minor stroke are treated, comparing two methods: one using a drug called IVT and another method called MT, versus just IVT alone.
- They analyzed data from patients treated in Italy to see which method led to better health outcomes after a stroke.
- The results showed that while IVT plus MT had more complications in the short term, both treatment methods had similar long-term recovery outcomes.
Efficacy and safety of mechanical thrombectomy (MT) for stroke with posterior circulation large vessel occlusion (LVO) is still under debate. We aimed to compare the outcomes of stroke patients with posterior circulation LVO treated with intravenous thrombolysis (IVT) (< 4.5 h after symptom onset) plus MT < 6 h after symptom onset with those treated with IVT alone (< 4.

- The study investigates predictors of hemorrhagic transformation (HT) and cerebral edema (CED) in stroke patients undergoing endovascular treatment after experiencing large vessel occlusion (LVO).
- It analyzes data from 1,400 patients to find clinical and procedural factors associated with these complications, identifying variables like diabetes, NIHSS scores, and ASPECTS ratings as significant predictors.
- Results show that HT occurred in 18% of patients and CED in 19.2%, with general anesthesia linked to a lower risk of HT, while factors like longer onset-to-groin times and invasive procedures raised the risk for both complications.
Background: Heart failure (HF) is the second most important cardiac risk factor for stroke after atrial fibrillation (AF). Few data are available on mechanical thrombectomy (MT) in acute ischemic stroke (AIS) patients with HF.
Methods: The source of data is the multicentre Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS).
Background And Purpose: The aim was to identify baseline clinical and radiological/procedural predictors and 24-h radiological predictors for clinical and functional outcomes in stroke patients obtaining complete recanalization in one pass of mechanical thrombectomy (MT) in an optimal baseline and procedural setting.
Methods: A retrospective analysis was conducted of prospectively collected data from 924 stroke patients with anterior large vessel occlusion, Alberta Stroke Program Early Computed Tomography (ASPECT) score ≥6 and pre-stroke modified Rankin Scale score 0, who started MT ≤6 h from symptom onset and obtained first-pass complete recanalization. A first logistic regression model was performed to identify baseline clinical predictors and a second model to identify baseline radiological/procedural predictors.
Article Synopsis
- The study aimed to evaluate the safety and effectiveness of administering intravenous thrombolysis (IVT) between 4.5 to 9 hours after a stroke compared to treatment within 4.5 hours, while also examining the role of advanced neuroimaging for patient selection.
- Out of 15,827 patients, only 663 received IVT between 4.5 to 9 hours post-stroke, with no significant differences found in rates of symptomatic intracranial hemorrhage, poor functional outcomes, or mortality when compared to those treated within 4.5 hours.
- Advanced neuroimaging in patients treated between 4.5 to 9 hours was linked to a 50% reduction in mortality, suggesting that it can
Introduction: The routinely used computed tomography (CT)-based workup in the setting of acute ischemic stroke (AIS) includes non-contrast brain CT, CT angiography (CTA), and CT perfusion. Several CT, CTA, CTP-based radiological biomarkers of hemorrhagic transformation (HT) were reported.
Aim Of The Study: To assess the predictive value of the combined multimodal CT parameters for HT after AIS and proposal of predictive scoring scale.
Background: The benefit, safety, and time intervals of mechanical thrombectomy (MT) in patients with in-hospital stroke (IHS) are unclear. We sought to evaluate the outcomes and treatment times for IHS patients compared with out-of-hospital stroke (OHS) patients receiving MT.
Methods: We analyzed data from the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS) between 2015 and 2019.
Article Synopsis
- International guidelines advise against using intravenous thrombolysis (IVT) in ischemic stroke patients who have recently taken direct oral anticoagulants (DOAC).
- A multicenter study examined the risk of symptomatic intracranial hemorrhage (sICH) in 832 patients who underwent IVT within 48 hours of DOAC use, compared to over 32,000 controls without recent DOAC intake.
- Results highlighted varied outcomes based on prior DOAC therapy, with focus on sICH incidence measured through established stroke scales, and included an analysis of DOAC levels and reversal treatments prior to IVT.
Article Synopsis
- The study investigates the safety and outcomes of intravenous thrombolysis (IVT) in patients aged 90 and older compared to those younger than 90, using data from the TRISP registry.
- It finds that although the risk of symptomatic intracranial hemorrhage is similar between both age groups, patients aged 90 and older face significantly higher odds of death and poor functional outcomes after treatment.
- The conclusions suggest that while IVT may be just as safe in very elderly patients, the increased mortality and poor recovery rates may not be directly linked to the IVT treatment itself.
