High risk factors for stroke such as smoking and blood pressure are not equally represented throughout the patient population. These are just two of the socioeconomic influences on cerebrovascular disease. One way to view this association is through the lens of the Area Deprivation Index (ADI), a measure of neighbourhood-level deprivation, and this was the approach of the study discussed in this episode. The study evaluated the association between the ADI and the treatment of ruptured intracranial aneurysms compared with unruptured intracranial aneurysms across multiple centres. Editor-in-Chief of JNIS, Dr. Felipe C. Albuquerque, interviews Dr. Alexandra Paul¹, author of the paper: Multicenter study of association between socioeconomic status and treatment of ruptured cerebral aneurysms compared to unruptured cerebral aneurysms: insights from 4,517 patients using the area deprivation index

The 2013 ARUBA trial concluded that medical management alone is superior to medical management with interventional therapy for patients with unruptured brain arteriovenous malformations. A study was conducted to analyze AVM treatment and epidemiologic response to the ARUBA trial. Following ARUBA, there has been a stark decrease in interventions for uAVMs. Nationwide rAVM discharge incidence is inversely correlated with uAVM intervention rate. Less uAVM interventions may lead to a substantial increase in AVM rupture incidence. In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque speaks with Dr. Evan Luther(1) and Dr. Robert Starke(2) about their paper "Unruptured arteriovenous malformation intervention rate is inversely correlated with ruptured AVM discharge incidence" - https://jnis.bmj.com/content/12/suppl_1/a163.

Survival for glioblastoma remains very poor despite decades of research, with a 5-year survival of only 5%. Technological improvements that have revolutionized treatment of ischemic stroke and brain aneurysms have great potential in providing more precise and selective delivery of cancer therapeutic agents to brain tumors. In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque speaks with Dr. Stephen Chen (1)and Dr. Peter Kan (2) about their paper "Perfusion-guided endovascular super-selective intra-arterial infusion for treatment of malignant brain tumors". The paper describes a technique using perfusion guidance to enhance the precision of endovascular super-selective intra-arterial (ESIA) infusions of mesenchymal stem cells loaded with Delta-24 in the treatment of glioblastoma. This technique enhances targeted super-selective delivery of therapeutic agents for brain tumors. Paper available online (https://jnis.bmj.com/content/14/6/533) and in June print issue of JNIS.

Sex disparities in acute ischemic stroke outcomes are well reported with IV thrombolysis. Despite several studies, there is still a lack of consensus on whether endovascular thrombectomy (EVT) outcomes differ between men and women. In this podcast, we discuss the Selection for Endovascular Treatment in Acute Ischemic Stroke (SELECT) study, in which women had similar discharge outcomes as men following EVT, in a propensity-matched cohort, but the improvement from discharge to 90 days was significantly worse in women, suggesting the influence of post-discharge factors.

Venous sinus stenting (VSS) is a safe, effective, and increasingly popular treatment option for selected patients with idiopathic intracranial hypertension (IIH). Serious complications associated with VSS are rarely reported.

In this podcast, JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Dr. Kyle Fargen, from the Department of Neurosurgery, Wake Forest University, Winston-Salem, North Carolina, about a case series in which serious complications after VSS were identified retrospectively from multicenter databases. The cases are reviewed and learning points regarding complication avoidance and management are presented in his paper (https://jnis.bmj.com/content/early/2021/04/27/neurintsurg-2021-017361).

In this podcast, we discuss the COMPASS: a trial of aspiration thrombectomy versus stent retriever thrombectomy as first-line approach for large vessel occlusion, comparing patients with and without prior intravenous (IV) alteplase administration. JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Maxim Mokin, from the Department of Neurosurgery and Brain Repair, University of South Florida, Tampa, USA, about the post hoc analysis. which concludes that prior administration of IV alteplase may adversely affect the efficacy of aspiration, whilst it does not seem to influence the stent retriever first approach to MT in patients with anterior circulation ELVO.

M2 occlusions can present with serious neurological deficits, resulting in large infarcts and significant morbidity and mortality. The paper discussed in this podcast concludes that patients with M2 occlusions and higher baseline deficits (NIHSS score ≥9) may benefit from endovascular therapy, thus potentially expanding the category of acute ischemic strokes amenable to intervention.

Listen to the conversation between the Editor-in-Chief of JNIS, Felipe de Albuquerque, and Ansaar Rai (Department of Interventional Neuroradiology, West Virginia University Hospital, USA), who is the co-author of “A population-based incidence of M2 strokes indicates potential expansion of large vessel occlusions amenable to endovascular therapy”.

A low baseline Alberta Stroke Programme Early CT Score (ASPECTS) is strongly associated with low rates of favorable outcome in patients with acute stroke. The study discussed in this podcast evaluated the efficacy and safety of revascularization therapy in patient with ASPECTS ≤5 in anterior circulation infarct, concluding that revascularization therapy contributed to a favorable clinical outcome at 90 days, especially in patients younger than 70 years. The Editor-in-Chief of JNIS Felipe Albuquerque is joined by Vincent Costalat (Department of Neuroradiology, CHRU Gui de Chauliac, Montpellier, France), who co-authored the paper: "Favorable revascularization therapy in patients with ASPECTS ≤ 5 on DWI in anterior circulation stroke".

JNIS Associate Editor Joshua Hirsch is joined by Shazam Hussain (Cerebrovascular Center, Cleveland Clinic, Ohio, USA) and David Fiorella (Department of Neurosurgery, Stony Brook University, New York, USA) to discuss the June 2017's editorial in the Journal of Neurointerventional Surgery. In this commentary, they analyse the conclusions of the study “Public Health Urgency Created by the Success of Mechanical Thrombectomy Studies in Stroke”, published by Circulation, stating that the opinions of Drs Hopkins and Holmes “lead to unwarranted conclusions that have dangerous implications for patient care”. The authors of the JNIS editorial comment on three major points of controversy: (1) a disregard for training, expertise, and experience in the management of a disease that may lead to death or disability when treating physicians do not have them; (2) a misunderstanding of the fundamental underpinnings of stroke physiology and anatomy; (3) a false association between a real problem (undeveloped systems of care) and a spurious assumption (ie, that there are not enough physicians trained to perform intracranial MT). We examine these concerns below. The editorial “In defense of our patients” was written on behalf of the Society of NeuroInterventional Surgery, the Cerebrovascular Section of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons, and the Society of Vascular and Interventional Neurology.

The direct aspiration first pass technique (ADAPT) has been introduced as a simple and fast method for achieving good angiographic and clinical outcomes using large bore aspiration catheters for the treatment of acute ischemic stroke (AIS). A study recently published in JNIS by Dr Turk et al. conclude that ADAPT is an effective method to achieve good clinical and angiographic outcomes, and serves as a useful firstline method for revascularization. In this podcast, The Editor-in-Chief of JNIS Felipe Albuquerque and Aquilla Turk discuss the details of this single center's long term experience with ADAPT. The paper “Long term experience using the ADAPT technique for the treatment of acute ischemic stroke” can be found on the JNIS website (http://jnis.bmj.com/content/9/5/437) and on the May 2017's edition of the journal.

There has been a large increase in the number of non-invasive neurovascular studies performed in the last decade, particularly CT angiograms and MR angiograms. What has this meant for catheter-based angiography? This episode looks at an analysis done on a large claims database in the USA, to observe trends in imaging modalities, as well as the distinctions in use by neurosurgeons and radiologists.

Dr Felipe C. Albuquerque, Editor-in-Chief of JNIS, interviews Dr. Francis Jareczek¹ and Dr. D. Andrew Wilkinson¹, two of the authors of the paper:  National trends in catheter angiography and cerebrovascular imaging in a group of privately insured patients in the US.
