Force and aspiration analysis of the ADAPT technique in acute ischemic stroke treatment
Conclusions The physical and fluid dynamic properties of currently available catheters suggest that the 5MAX ACE is the optimal catheter to use in direct aspiration for stroke therapy.

Transradial access in acute ischemic stroke intervention
Conclusions Failure of TFA in the endovascular treatment of AIS is uncommon but leads to unacceptable delays in reperfusion and poor outcomes. Standardization of benchmarks for access switch could serve as a guide for neurointerventionalists. TRA is a valid approach for the endovascular treatment of AIS.

Pulmonary and circulatory parameter guided anesthesia in patients with ischemic stroke undergoing endovascular recanalization
Conclusions In patients receiving endovascular stroke treatment under general anesthesia, the cumulative dose of norepinephrine was an independent predictor of an unfavorable outcome. Further studies are needed to evaluate the optimal management of blood pressure in these patients, and whether avoidance of catecholamines could partly explain the improved outcomes for patients treated under conscious sedation in retrospective studies.

Unfavorable neurological outcome in diabetic patients with acute ischemic stroke is associated with incomplete recanalization after intravenous thrombolysis
Conclusions Diabetic patients with AIS had unfavorable neurological outcome, potentially linked to incomplete recanalization after IVT.

CTA collateral score predicts infarct volume and clinical outcome after endovascular therapy for acute ischemic stroke: a retrospective chart review
Conclusions Good CS predict smaller infarct volumes and better clinical outcome in patients recanalized with EVT. These data support the use of this technique in selecting patients for EVT. Poor CS should be considered as an exclusion criterion for EVT as patients with poor CS have poor clinical outcomes despite recanalization.

Improved clinical outcome 3 months after endovascular treatment, including thrombectomy, in patients with acute ischemic stroke: a meta-analysis
Conclusions Endovascular treatment in addition to intravenous thrombolysis for acute ischemic stroke leads to an improved clinical outcome after 3 months, compared with patients receiving intravenous thrombolysis alone.

Mechanical thrombectomy with the Trevo ProVue device in ischemic stroke patients: does improved visibility translate into a clinical benefit?
Conclusions Neurothrombectomy with TPV is feasible, effective, and safe. The recanalization rate compares favorably with reported data in the literature. Improved structural radiopacity may facilitate neurothrombectomy or influence the course of action during retrieval.

Initial experience using the 3MAX cerebral reperfusion catheter in the endovascular treatment of acute ischemic stroke of distal arteries
Conclusions Our initial experience suggests that treatment of distal cerebrovascular occlusions with the 3MAX catheter is feasible. We achieved complete recanalization in all cases without unexpected complications while obtaining good clinical results. However, larger studies are necessary to establish its benefits and its safety.

Mechanical thrombectomy versus systemic thrombolysis in MCA stroke: a distance to thrombus-based outcome analysis
Conclusions In patients with an acute MCA occlusion and a DT <16 mm, IVT–MT leads to a significantly better outcome than in patients treated with IVT alone.

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.

Longer procedural times are independently associated with symptomatic intracranial hemorrhage in patients with large vessel occlusion stroke undergoing thrombectomy
Conclusions Our data support an association between the risk of SICH and a longer procedure time, but no association between procedural times and the final infarction volume or long-term functional outcomes was found.

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.

Topographic distribution of cerebral infarct probability in patients with acute ischemic stroke: mapping of intra-arterial treatment effect
Conclusions Probability maps intuitively visualize the topographic distribution of infarct probability due to treatment, which makes it a promising tool for estimating the effect of treatment.

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.

Acute Recanalization of Thrombo-Embolic Ischemic Stroke with pREset (ARTESp): the impact of occlusion time on clinical outcome of directly admitted and transferred patients
Conclusions pREset proved to be safe and effective for the treatment of acute intracranial vessel occlusion. Increased occlusion time impaired clinical outcome in TP. Trial registration number NCT02437409; Results.
