Abstract
Pediatric arterial ischemic stroke is a rare but increasingly acknowledged disorder. Large vessel occlusions in this population have been treated off-label with endovascular thrombectomy. However, there is limited evidence to guide management. Small children, before the age of five when the cerebrovasculature reaches adult size, present additional challenges. We report the case of cardioembolic basilar occlusion in a two-year-old and the technical details of endovascular management, currently lacking in published literature. We employed a 5 French slender sheath, typically used for radial access, as a femoral short sheath. We accessed the dominant vertebral artery with a 5 French intermediate catheter, navigated with a typical 0.027-inch microcatheter and 0.014-inch microwire, and performed direct aspiration thrombectomy of the basilar clot. No closure device was employed. The patient had a near-complete and durable recovery. Small children present additional challenges for the endovascular management of stroke. Pre-procedural imaging can be used to design an aspiration-capable system appropriate for the child's size. Endovascular thrombectomy in children is feasible with some modifications to adult protocols.

Abstract
This extensive review explores the intricacies of the three principal mechanical thrombectomy techniques: the stent retriever technique, contact aspiration technique, and a combined approach, and their application in managing acute ischemic stroke. Each technique operates uniquely on the thrombus, leading to differences in their efficacy. Factors including clot size, clot stiffness, vessel tortuosity, and the angle of interaction between the aspiration catheter and the clot significantly influence these differences. Clinical trials and meta-analyses have shown the overall equivalency of these techniques for the treatments of large vessel occlusion and distal medium vessel occlusions. However, there are nuanced differences that emerge under specific clinical circumstances, highlighting the absence of a one-size-fits-all strategy in acute ischemic stroke management. We emphasize the need for future investigations to elucidate these nuances further, aiming to refine procedural strategies and individualize patient care for optimal outcomes.

Stroke 2023; 54:2512-2521.

Abstract
BACKGROUND Aspiration catheters (ASPs) and stentriever thrombectomy devices have comparable safety and efficacy in anterior circulation ischemic strokes. However, there is lack of high-quality comparative data in acute basilar artery occlusions. Our objective is to compare the outcomes and safety of ASPs and stentriever devices in acute basilar artery occlusions. METHODS This is an analysis of the retrospectively established PC-SEARCH Thrombectomy (Posterior-Circulation Ischemic Stroke Evaluation: Analyzing Radiographic and Intraprocedural Predictors for Mechanical Thrombectomy) registry. Patients were dichotomized based on their first-line thrombectomy device (ASP and stentriever) and associated with their 90-day functional outcomes, intraprocedural metrics, and safety measures. Propensity analysis based on unequal baseline characteristics was performed. Consecutive patients with acute basilar artery occlusions who received mechanical thrombectomy were included from January 2015 to December 2021. Patients received either first-line contact aspiration or stentriever mechanical thrombectomy. Primary clinical and safety outcomes were 90-day functional independence measured by a modified Rankin Scale score of 0 to 3 and symptomatic intracranial hemorrhage, respectively. Secondary outcomes included puncture-recanalization times, first-pass recanalization rates, crossovers to other thrombectomy device, and neurological/hospital complications. RESULTS Five hundred eighteen patients were included in the registry, and a total of 383 patients were included (mean [SD] age, 65.5 [15] years; 228 [59%] men) in this analysis. Of these, 219 patients were first-line ASP while 164 patients received first-line stentriever devices. Median premorbid modified Rankin Scale was zero and median presenting National Institutes of Health Stroke Scale was 17 (interquartile range, 8-26). The proportion of favorable functional outcome was similar between the 2 techniques before (47.3% versus 42.5%; odds ratio, 1.22 [95% CI, 0.78-1.89]; P=0.38) and after propensity matching (odds ratio, 1.46 [95% CI, 0.85-2.49]; P=0.17). In our propensity-matched cohorts, puncture-recanalization times (18 versus 52 minutes; P<0.01) favored first-line ASP; however, first-pass recanalization rates (43.5% versus 44.5%; P=0.90) were similar between groups. First-line ASP was associated with higher rates of crossover (22% versus 6%; P<0.01), whereas stentriever was associated with higher rates of symptomatic intracranial hemorrhage (9.8% versus 3.4%; P=0.04). CONCLUSIONS First-line ASP and stentriever methods demonstrated similar functional outcome and recanalization rates. Stentriever methods were associated with higher rates of symptomatic intracranial hemorrhage, whereas ASPs were associated with higher rates of crossover to alternative technique in patients with acute basilar occlusions.

Abstract
Posterior circulation infarcts comprise approximately 25% of ischemic strokes but are less often treated with recanalization therapy and have longer treatment delays compared with anterior circulation strokes. Among posterior circulation strokes, basilar artery occlusion is associated with the most severe deficits and the worst prognosis. Endovascular thrombectomy is a standard of care for patients with anterior circulation large vessel occlusion, but not until recently were the first randomized controlled trials on endovascular thrombectomy in basilar artery occlusion published. Two of the trials were neutral, whereas two others showed better functional outcome after thrombectomy up to 24 hours of symptom onset compared with best medical treatment, which in most cases had low rates of intravenous thrombolysis. According to observational data, thrombectomy seems to be safe also in isolated posterior cerebral artery occlusions and might be an option for selected patients, even if its outcome benefit is yet to be demonstrated.

Abstract
BACKGROUND Basilar artery occlusion is a rare and severe condition. The effectiveness of endovascular thrombectomy in patients with basilar artery occlusion was unclear until recently, because these patients were excluded from most trials of endovascular thrombectomy for large-vessel occlusion ischaemic stroke. RECENT DEVELOPMENTS The Basilar Artery International Cooperation Study (BASICS) and the Basilar Artery Occlusion Endovascular Intervention versus Standard Medical Treatment (BEST) trials, specifically designed to investigate the benefit of thrombectomy in patients with basilar artery occlusion, did not find significant evidence of a benefit of endovascular thrombectomy in terms of disability outcomes at 3 months after stroke. However, these trials suggested a potential benefit of endovascular thrombectomy in patients presenting with moderate-to-severe symptoms. Subsequently, the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) and the Basilar Artery Occlusion Chinese Endovascular (BAOCHE) trials, which compared endovascular thrombectomy versus medical therapy within 24 h of onset, showed clear benefit of endovascular thrombectomy in reducing disability and mortality, particularly in patients with moderate-to-severe symptoms. The risk of intracranial haemorrhage with endovascular thrombectomy was similar to the risk in anterior circulation stroke. Thrombectomy was beneficial regardless of age, baseline characteristics, the presence of intracranial atherosclerotic disease, and time from symptom onset to randomisation. Therefore, the question of whether endovascular thrombectomy is beneficial in basilar artery occlusion now appears to be settled in patients with moderate-to-severe symptoms, and endovascular thrombectomy should be offered to eligible patients. WHERE NEXT?: Key outstanding issues are the potential benefits of endovascular thrombectomy in patients with mild symptoms, the use of intravenous thrombolysis in an extended time window (ie, after 4·5 h of symptom onset), and the optimal endovascular technique for thrombectomy. Dedicated training programmes and automated software to assist with the assessment of imaging prognostic markers could be useful in the selection of patients who might benefit from endovascular thrombectomy. Large international research networks should be built to address knowledge gaps in this field and allow the conduct of clinical trials with fast and consecutive enrolment and a diverse ethnic representation.

Abstract
BACKGROUND Mechanical thrombectomy (MT) has become the standard of care for stroke patients. The majority of the clinical trials and publications analyzing the outcomes related to the procedures report interventional performance by experienced practitioners. However, few of them individualize their preliminary metrics according to the operator's experience. OBJECTIVE To summarize the literature and report safety and efficacy outcomes following MT procedures and correlate them with the operator's experience. Primary outcomes were successful recanalization, defined as modified thrombolysis in cerebral infarction greater or equal to 2b or 3, duration of the procedure measured in minutes, and serious adverse event. METHODS This systematic review was performed according to the PRISMA guidelines. The PubMed, Embase, and Cochrane databases were utilized. RESULTS There were six studies comprising 9348 patients (mean age 69.8 years; 51.2% males), and 9361 MT procedures were included. Each publication used for this review used a different experience definition to report their data. Higher interventionists' experience demonstrated a positive relationship with the possibility of successful recanalization and an inverse relationship with the duration needed for the operation in almost all of the included studies. As for the complications, none of the authors reported a statistically significant risk reduction of an adverse event, except Olthuis et al. correlating increasing training with lower odds of stroke progression. CONCLUSIONS A higher experience level is associated with better recanalization rates and shorter procedural duration in MT operations. Further studies are warranted to define the minimum required level of experience for operational autonomy.

Abstract
The efficacy of endovascular treatment (EVT) in patients with posterior circulation stroke has not been proven. Two recent randomized controlled trials failed to show improved functional outcomes after EVT for posterior circulation stroke (PC-EVT). However, promising results for two additional randomized controlled trials have also been presented at a recent conference. Studies have shown that patients undergoing PC-EVT had a higher rate of futile recanalization than those undergoing EVT for anterior circulation stroke. These findings call for further identification of prognostic factors beyond recanalization. The significance of baseline clinical severity, infarct volume, collaterals, time metrics, core-penumbra mismatch, and methods to accurately measure these parameters are discussed. Furthermore, their interplay on EVT outcomes and the potential to individualize patient selection for PC-EVT are reviewed. We also discuss technical considerations for improving the treatment efficacy of PC-EVT.
