Impact of thrombus length on recanalization and clinical outcome following mechanical thrombectomy in acute ischemic stroke
Conclusions In this study, thrombus length had no relevant impact on recanalization, neurological outcome, or intraprocedural complications following mechanical thrombectomy of middle cerebral artery occlusions. Therefore, mechanical thrombectomy with stent retrievers can be attempted with large clots.

CT angiography-based collateral flow and time to reperfusion are strong predictors of outcome in endovascular treatment of patients with stroke
Conclusions CTA is a valid tool for assessing the ability of CF to predict clinical outcome in patients with AIS treated with mechanical thrombectomy. Limiting time to reperfusion is of definite value in patients with good collaterals and also to some extent in those with poor collaterals.

Stroke prevention by endovascular treatment of carotid and vertebral artery dissections
Conclusions Patients with CAD and VAD differ significantly in presentation, indications for treatment, and treatment methods. Endovascular treatment of CAD and VAD has low procedural morbidity and is associated with a low incidence of future stroke.

Impact of ASPECT scores and infarct distribution on outcomes among patients undergoing thrombectomy for acute ischemic stroke with the ADAPT technique
Conclusions Patients with moderate-sized core infarcts involving various distributions in either hemisphere can potentially achieve similar good outcomes compared with those with no core infarction at presentation. A treatment algorithm for acute ischemic stroke, which employs hardline ASPECTS thresholds or excludes patients with basal ganglia infarcts, might preclude patients who would potentially benefit from mechanical thrombectomy with ADAPT.

Predictors of false-positive stroke thrombectomy transfers
Conclusions Clinical scales appear to overdiagnose LVO and may be responsible for the majority of our stroke code transfers not undergoing thrombectomy. Primary stroke centres therefore have reason to develop the capability to rapidly acquire and interpret a CTA in patients with suspected LVO prior to transfer. Such efforts may reduce the costs associated with unnecessary thrombectomy transfers.

Endovascular interventions for acute stroke: past practice and current research
Introduction The way clinical care and research are currently conceived is entangled in multiple problems. While the problems are universal, nowhere were they more painfully experienced than in the acute care of patients with severe stroke. While we are celebrating that we now possess evidence that patients can benefit from endovascular interventions, we should not miss the opportunity to review the difficult path that led to this point and reflect on how it could be improved. A narrative review of the past and current status of care and research in endovascular treatment of acute stroke may serve to expose the problems an...

A population-based incidence of acute large vessel occlusions and thrombectomy eligible patients indicates significant potential for growth of endovascular stroke therapy in the USA
Conclusions This study estimates an LVO incidence of 24 per 100 000 person-years (95% CI 20 to 28). A current estimated annual thrombectomy rate of three procedures per 100 000 people indicates significant potential increase in the volume of endovascular procedures and the need to develop systems of care.

Endovascular treatment of acute ischemic stroke in nonagenarians compared with younger patients in a multicenter cohort
Conclusions Nonagenarians are at a substantially higher risk of a poor 90-day outcome after EVT than younger patients. However, a small subset of nonagenarians may benefit from EVT, particularly if they have a good pre-stroke functional status. Further research is needed to identify factors associated with favorable outcome in this age cohort.

Mechanical thrombectomy for pediatric acute ischemic stroke: review of the literature
Conclusions This study suggests that mechanical thrombectomy in pediatric patients presenting with high pediatric NIH Stroke Scale scores and proximal large vessel occlusion is associated with high recanalization rates and excellent clinical outcome, although this is a retrospective review and the sample size is too small to make any definitive conclusions. This study provides class IVC evidence that endovascular treatment of pediatric AIS increases the chance of a good clinical outcome.

Factors associated with perforator stroke after selective basilar artery angioplasty or stenting
Conclusions Diabetes, time from last symptom to procedure, and pre-procedure stenosis percentage may be factors affecting the risk of perforator stroke associated with basilar artery angioplasty and/or stenting. These factors should be considered in planning of potential basilar artery angioplasty and/or stenting and prospectively evaluated in future multicenter trials.

Timeline of blood pressure changes after intra-arterial therapy for acute ischemic stroke based on recanalization status
Conclusions SBP falls significantly in patients with AIS with large vessel occlusion who recanalize with IAT. While SBP in non-recanalized patients also drops from baseline, it occurs to a lesser degree and stays higher only for a short period of time before falling to similar levels as in recanalized patients.

Distinction between contrast staining and hemorrhage after endovascular stroke treatment: one CT is not enough
Conclusions There are no density thresholds for PCHDs that allow predicting the absence or presence of hemorrhage with 100% specificity and acceptable sensitivity. A CT scan performed at least 19–24 h after endovascular therapy is the only reliable method to differentiate contrast staining from hemorrhage.

ASPECTS discrepancies between CT and MR imaging: analysis and implications for triage protocols in acute ischemic stroke
Conclusions The study suggests that patients with NIHSS scores at admission of <16 and patients with CT ASPECTS >7 have a higher likelihood of agreement between CT and DWI based on an ASPECTS cut-off value of 6. Additional MRI for triage in patients with NIHSS at admission of >16, and ASPECTS of 6 or 7 may be more likely to change management. Unsurprisingly, patients with low CT ASPECTS had good correlation with MRI ASPECTS.

Remote aspiration thrombectomy in large vessel acute ischemic stroke
We report a three case series of patients with acute ischemic stroke from supraclinoidal internal carotid artery occlusions treated with remote aspiration thrombectomy through a BGC placed at the cervical internal carotid artery, leading to complete reperfusion without the need for intracranial catheterization. Remote thrombectomy in the setting of intracranial internal carotid artery occlusion may constitute a relatively fast and inexpensive initial thrombectomy maneuver. Further investigation is warranted.

Comparison of four different collateral scores in acute ischemic stroke by CT angiography
Conclusions Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume. This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion.

Aneurysms in the target vessels of stroke patients subjected to mechanical thrombectomy: prevalence and impact on treatment
Conclusions The prevalence of aneurysms is relatively high in patients with LVO stroke, particularly in older, female, hypertensive patients, presumably reflecting overlapping risk factors. MTE should not be withheld from patients with LVO stroke with aneurysms, but particularly cautious approaches may be warranted. Further research in larger samples is required to obtain precise data on the prevalence and associated complication rates in MTE procedures. This is necessary to estimate the true risk and to tailor endovascular strategies in these patients.

Severe hemiparesis as a prehospital tool to triage stroke severity: a pilot study to assess diagnostic accuracy and treatment times
Conclusions We have presented a pilot study showing that severe hemiparesis or hemiplegia may be a reasonable prehospital tool in recognizing patients requiring endovascular treatment. Patients being identified earlier may be treated faster and potentially improve outcomes. Further prospective controlled studies are required to assess the impact on outcomes and cost effectiveness using this methodology.
