Clinical Results of the Advanced Neurovascular Access Catheter System Combined With a Stent Retriever in Acute Ischemic Stroke (SOLONDA).

Background: The Advanced Neurovascular Access (ANA) thrombectomy system is a novel stroke thrombectomy device comprising a self-expanding funnel designed to reduce clot fragmentation by locally restricting flow while becoming as wide as the lodging artery. Once deployed, the ANA device allows distal aspiration combined with a stent retriever to mobilize the clot into the funnel where it remains copped during extraction. We investigated the safety and efficacy of ANA catheter system.

Posterior Fossa Venous Drainage.

This paper aims to make simple the evaluation of the main veins related to the brainstem and cerebellum. Posterior fossa venous drainage is best understood in context with its three main collectors: superior: toward the Vein of Galen; posterior: toward the torcular complex; and anterior: toward the superior petrosal sinus. A fourth possible drainage path, often harder to distinguish, is directed toward the inferior petrosal sinus.

Transradial access for diagnostic angiography and interventional neuroradiology procedures: A four-year single-center experience.

Purpose: The objective of this study was to assess the efficacy and safety of transradial access for diagnostic angiography and interventional neuroradiology procedures.

Methods: This was a retrospective analysis of a single-center experience based on 225 patients attended between August 2015 and October 2019, in which transradial access was used for diagnostic angiography and endovascular interventions. Ultrasound-guided access was done at the level of the forearm or anatomical or snuffbox (distal transradial access).

Primary endovascular treatment for acute ischemic stroke in teenage patients: a short case series.

Purpose: To analyze the safety and efficacy of primary endovascular treatment (EVT) for acute ischemic stroke (AIS) in patients younger than 18 years of age.

Methods: Review of 4 patients < 18 years of age with AIS, prospectively enrolled in an electronic database registry for acute ischemic stroke patients who underwent thrombectomy at tertiary centers, from January 2011 to February 2017. Clinical and imaging data were analyzed.

Cost-effectiveness of mechanical thrombectomy using stent retriever after intravenous tissue plasminogen activator compared with intravenous tissue plasminogen activator alone in the treatment of acute ischaemic stroke due to large vessel occlusion in Spain.

Introduction: To assess the cost-effectiveness of stent-retriever mechanical thrombectomy and intravenous tissue plasminogen activator compared with intravenous tissue plasminogen activator alone in patients with acute ischaemic stroke due to large vessel occlusions in Spain.

Materials And Methods: Clinical data were taken from the SWIFT PRIME clinical trial. A lifetime Markov state transition model defined by the modified Rankin Scale score was developed to estimate costs and health outcomes (life years gained and quality adjusted life years).

Treatment of distal anterior cerebral artery aneurysms with the Pipeline Embolization Device.

Aneurysms of the anterior cerebral artery (ACA) located distal to the anterior communicating artery complex (ACOM) remain challenging to treat with surgical clip reconstruction as well as with endovascular coil-embolization strategies. We have treated five complex geometry distal ACA aneurysms with endoluminal reconstruction using the Pipeline Embolization Device (PED). Two aneurysms were of the dysplastic fusiform type.

Association Between Time to Reperfusion and Outcome Is Primarily Driven by the Time From Imaging to Reperfusion.

Background And Purpose: A progressive decline in the odds of favorable outcome as time to reperfusion increases is well known. However, the impact of specific workflow intervals is not clear.

Methods: We studied the mechanical thrombectomy group (n=103) of the prospective, randomized REVASCAT (Randomized Trial of Revascularization With Solitaire FR Device Versus Best Medical Therapy in the Treatment of Acute Stroke due to Anterior Circulation Large Vessel Occlusion Presenting Within Eight Hours of Symptom Onset) trial.

Outcomes of a contemporary cohort of 536 consecutive patients with acute ischemic stroke treated with endovascular therapy.

Background And Purpose: We sought to assess outcomes after endovascular treatment/therapy of acute ischemic stroke, overall and by subgroups, and looked for predictors of outcome.

Methods: We used data from a mandatory, population-based registry that includes external monitoring of completeness, which assesses reperfusion therapies for consecutive patients with acute ischemic stroke since 2011. We described outcomes overall and by subgroups (age ≤ or >80 years; onset-to-groin puncture ≤ or >6 hours; anterior or posterior strokes; previous IV recombinant tissue-type plasminogen activator or isolated endovascular treatment/therapy; revascularization or no revascularization), and determined independent predictors of good outcome (modified Rankin Scale score ≤2) and mortality at 3 months by multivariate modeling.
