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.

The Woven EndoBridge (WEB) device has FDA approval for treatment of wide-necked intracranial bifurcation aneurysms. It has been shown to result in adequate occlusion in bifurcation aneurysms overall, but its usefulness in the individual bifurcation locations has been evaluated separately only in few case series, which were limited by small sample sizes. In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, interviews Dr. Nimer Adeeb (1)and Dr. Adam Dmytriw (2) on their paper "Comparing treatment outcomes of various intracranial bifurcation aneurysms locations using the Woven EndoBridge (WEB) device".

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. JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, interviews Johanna Fifi (Department of Neurosurgery, Icahn School of Medicine at Mount Sinai, New York) and Amrou Sarraj (Department of Neurology, Case Western Reserve University School of Medicine, Cleveland, Ohio).

In the latest podcast, we discuss the joint expedited recommendations from the European Stroke Organisation (ESO) and the European Society for Minimally Invasive Neurological Therapy (ESMINT) on indication for intravenous thrombolysis before mechanical thrombectomy in patients with acute ischemic stroke and anterior circulation large vessel occlusion.

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.

Flow diversion of intracranial aneurysms with the Pipeline Embolization Device (PED) is commonly performed, but the value of long-term angiographic follow-up has not been rigorously evaluated. The study discussed in this podcast examines the prevalence of actionable findings of aneurysm recurrence and development of in-stent stenosis in a cohort of patients that underwent long-term angiographic follow-up at multiple time points. JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews Dr Akash P. Kansagra, from the Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, USA.
